# API Reference

# Introduction

Sum&Substance's API allows you to send and receive applicants’ data and documents for verification through simple RESTful APIs. API responds with JSON payload (unless otherwise stated). When data payload should be provided, it expects parameters to be passed in valid JSON (except when stated otherwise) with the Content-Type: application/json header being set.

All incompatible changes made to API will be versioned and won't affect existing endpoints. However, we may add additional fields to JSON response without any notice or API versioning. So it's not a good idea to rely on object mappers in your integration code that will fail on unknown properties.

Note that header names are not case-sensitive and may vary depending on your ways of implementation at both your requests and our responses.

We have two environments:

Sandbox: this is only needed when testing out your integration with Sumsub. No real checks are performed when in the sandbox environment.
Production: In order to provide you with access to the production environment, we require that the integration is tested first. We just want to make sure that everything works the way it should.

Both environments are available via api.sumsub.com and are controlled by the switch in the top right-hand corner of the dashboard. API accesses are regulated through the use of the X-App-Token authorization header value.

Previously, we used two different domains (test-api.sumsub.com and api.sumsub.com) - both are still accessible. If you'd like to use the Sandbox environment within api.sumsub.com and it's not available, please contact our technical support team.

# Authentication

All API queries must be made over HTTPS, and plain HTTP will be refused. You must include your X-App headers in all requests.

# App Tokens

This is the most secure method of talking to our API programmatically.

You can generate App Tokens in the dev space in our dashboard.

Full sized App Token and Secret Key values are shown only once at the dashboard in the moment of App Token creation, and their settings cannot be changed later.

# Making a request

All requests must contain the following headers:

X-App-Token - an App Token that you generate in our dashboard
X-App-Access-Sig - signature of the request in the hex format and lowercase (see below)
X-App-Access-Ts - number of seconds since Unix Epoch in UTC

# Signing a request

The value of the X-App-Access-Sig is generated by a sha256 HMAC algorithm using a secret key (provided upon App Token generation) on the bytes obtained by concatenating the following information:

A timestamp (value of the X-App-Access-Ts header) taken as a string
An HTTP method name in upper-case, e.g. GET or POST
URI of the request without a host name, starting with a slash and including all query parameters, e.g. /resources/applicants/123?fields=info
Request body, taken exactly as it will be sent. If there is no request body, e.g., for GET requests, don't include it.

Example of the string to be signed to get an accessToken: 1607551635POST/resources/accessTokens?userId=cfd20712-24a2-4c7d-9ab0-146f3c142335&levelName=basic-kyc-level&ttlInSecs=600

Your timestamp must be within 1 minute of the API server time. Make sure the time on your servers is correct.

# Examples

Here are some examples how you can sign requests

# Access tokens for SDKs

When initializing WebSDK or MobileSDK, an access token authentication must be used.

POST /resources/accessTokens?userId={userId}&levelName={levelName}

# REQUEST ARGUMENTS

Name	Type	Required	Description
ttlInSecs	Integer	No	Lifespan of a token in seconds. Default value is equal to 10 minutes.

levelName	String	Yes	A name of the level configured in the dashboard
externalActionId	String	No	An external action ID which will be bound to the token. More info about applicant actions you can find here.

If your userId or levelName contains reserved characters (e.g., "@", "+") it should be URL encoded otherwise you may get signature mismatch.

# RESPONSE

Name	Type	Description
token	String	A newly generated access token for an applicant.

An access token for applicant has limited access to the API, e.g., it’s only valid for 1 applicant and can't access other applicants.

# Example request

Copy
curl -X GET \
  'https://api.sumsub.com/resources/status/api'

# Errors

On API errors we return standard HTTP Status Codes.

Please note that we have a rate limiter for the following API requests that you may send. If there are too many requests from you, we will return status code 429. Please notify our team if you have to make a vast amount of requests during a particular time frame.

Response body contains a JSON payload with additional information. For example:

Copy
{
  "description": "Error analyzing file, unsupported format or corrupted file",

# Applicants API

# Creating an applicant

An applicant is an entity representing one physical person. It may have several ID documents attached, like an ID card or a passport. Many additional photos of different documents can be attached to the same applicant.

POST /resources/applicants?levelName={levelName}

When creating an applicant, you don't have to send us prefilled applicant data such as names, dob, addresses, etc. You only need to send us images and get the recognized document data by this method. It's the best way to increase your conversion because rejects of mismatches in names and typos will be excluded.

If you have requirements to make data cross-validation and have no possibility to perform it on your side you can use fixedInfo object to fill data like names, date of birth and address.

# REQUEST ARGUMENTS

Name	Type	Required	Description
levelName	String	Yes	Name of user verification steps configuration that you should set up at the dashboard.

phone	String	No	Applicant phone number.
lang	String	No	The language in which the applicant should see the result of verification in ISO 639-1 format.
metadata	Array of objects	No	Additional information that is not displayed to the end user ( Example: `[{"key": "keyFromClient", "value": "valueFromClient"}]` ).
info	Object	No	Basic information about the applicant.

An applicant entity with the associated id (refer to the example). Persist the id field after creating the applicant - it will be needed for further requests that you intend to make.

For the IDENTITY step we recommend the following document types: PASSPORT, ID_CARD, RESIDENCE_PERMIT, DRIVERS

If levelName contains reserved characters (e.g., "@", "+", white spaces as %20) it should be URL encoded otherwise you may get signature mismatch. The same applies to all endpoints below.

# Changing required document set (level)

This method updates required documents list according to the level provided. In case you need to add one more step to the check, for example, only id document and selfie have been requested at first, and after the check has been completed you need to get the proof of address. So you have to add one more step to the current list of required documents.

If you're using our SDKs you can just initialize it with suitable levelName on accessToken and SDK will change level automatically.

POST /resources/applicants/{applicantId}/moveToLevel?name={levelName}

Make sure to check an applicant status before changing the level. You won't be able to do that if reviewStatus of the applicant is pending, queued or onHold.

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID
levelName	String	Yes	Name of new user verification steps configuration from the dashboard.

# RESPONSE

A new requiredIdDocs and levelName will be returned.

# Adding an ID document

A method gets a multipart form: ID doc JSON metadata and, optionally, a document photo. If the ID doc with this type already exists, its data will be merged. Existing data will be overwritten if they also present in the new object. However, a new image will be added nonetheless. If document metadata are not known yet, just send type and a country. E.g. "PASSPORT" and "GBR". These two fields are mandatory.

POST /resources/applicants/{applicantId}/info/idDoc

# REQUEST HEADERS

Name	Type	Value
Content-Type	String	`multipart/form-data`
X-Return-Doc-Warnings	Boolean	`true`/`false`

Using header X-Return-Doc-Warnings allows determining if document data is readable and acceptable before moving applicant to pending status: in response errors or warnings array will present. In case of receiving errors uploaded image will be marked as inactive if something wrong with a document. For double-sided documents (FRONT_SIDE and BACK_SIDE of one idDocType value) both images will be marked as inactive even if you've got an error for only one of them. Array of warnings just makes a notice that there might be something wrong with a document.

Note that applicant won't able to be moved to pending status for a check if one of verification steps is not active (doesn't have active images within itself). To check if verification step is active you can call this method.

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID

# FORM DATA

Name	Type	Required	Description
metadata	Object	Yes	An object representing an ID document
content	Binary	No	A photo of a document

# REQUEST `metadata` BODY PART FIELDS

Name	Type	Required	Description
idDocType	String	Yes	See supported document types here
idDocSubType	String	No	`FRONT_SIDE`, `BACK_SIDE` or null
country	String	Yes	3-letter country code (Wikipedia)
firstName	String	No	First name
middleName	String	No	Middle name
lastName	String	No	Last name

number	String	No	Document number
dob	String	No	Date of birth
placeOfBirth	String	No	Place of birth

If a document is double-sided submit two images and set up idDocSubType properly (FRONT_SIDE and BACK_SIDE)
Make sure to send BACK_SIDE if FRON_SIDE was already sent otherwise verification step won't be completed, and you won't be able to initiate a check.

# Getting applicant data

During the verification we also extract data from the applicant's id docs. To get the full structured view of an applicant you should perform the following request.

GET /resources/applicants/{applicantId}/one

GET /resources/applicants/-;externalUserId={externalUserId}/one

You may want to use the second request when you don't know an applicant id yet. E.g., when WebSDK created an applicant for you and we called your webhook endpoint.

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant id
externalUserId	String	Yes	User id in your system

# RESPONSE

Response Code	Response	Reason
200	Applicant entity
400	Error JSON	Invalid applicant id provided
404	Error JSON	Applicant not found

The existence of each field depends on the documents submitted for verification and the regulations of verification.

It's basically an applicant that you've created (or we've created for you, e.g., via WebSDK) with augmented information in cases where a verification has been completed. The info.idDocs[] array of objects contains information extracted from applicants’ documents.

To make sure that you've fetched data from a relevant document you can get what idDocType and country was approved using this method.

As the described endpoint is actually quite generic (e.g., may return several applicants by an external id, but we omit such details in this document), it returns a list of items. However, if you provide an applicant id that exists, only 1 item will be returned.

You can find descriptions on response objects here.

# Changing provided info (fixedInfo)

If you'd like to alter data that you've provided us to cross-validate it with documents you can issue a PATCH request instead of creating a new applicant, which is highly discouraged. This method patches the fields in the fixedInfo key of the applicant.

PATCH /resources/applicants/{applicantId}/fixedInfo

# REQUEST ARGUMENTS

The body of fixedInfo must contain all those fields that have value. Null fields will be unset. So it's better to get previously filled data first with this method.

Name	Type	Required	Description
#{body}	Object	No	Field in the `fixedInfo` attribute that should be changed
applicantId	String	Yes	Applicant ID

You can take a look at available fixedInfo attributes here.

# Example request

Copy
curl -X PATCH \
  'https://api.sumsub.com/resources/applicants/609d68bf460647000aa2d87e/fixedInfo' \
  -H 'Content-Type: application/json' \

        "lastName" : "Peak",
        "dob" : "1990-01-01"
      }'

# Changing applicant data

If you want to change an applicant's data you can issue a PATCH request instead of creating a new applicant, which is highly discouraged. This method patches the fields in the info key of the applicant.

PATCH /resources/applicants/{applicantId}/info

# REQUEST ARGUMENTS

The body must contain only those fields that you intend to change. Null fields will be ignored. If you want to unset some fields, provide these in the unsetFields query parameter. Check the info attribute above for the list of supported fields.

Name	Type	Required	Description
#{body}	Object	No	Field in the `info` attribute that should be changed
applicantId	String	Yes	Applicant ID
unsetFields	String	No	Comma-separated list of fields to unset

# RESPONSE

A patched info entity. As this endpoint could be quite damaging if misused, please check that it returns expected results on the test environment — it's a client's responsibility to treat their applicants well 😃

# Example request

Copy
curl -X PATCH \

# Getting verification results

When we are talking about verification results we typically mean two labels:

Value	Description
GREEN	Everything is fine
RED	Some violations found

Once verification finished, we will send you a POST request with JSON payload to the URL provided to us while integrating. Oftentimes, there are different URLs for staging and production environments. We may send several types of webhooks, but the one of interest here is the applicantReviewed webhook. This type of webhook is expected to arrive at average after 3-5 minutes, but can take up to 24 hours, in theory.

If for some reason you missed the webhooks, don't worry: we make a note of everything that was attempted to be sent, and can resend failed webhooks at any point in time. If webhook request fails we attempt to resend it four times: after 5 minutes, 1 hour, 5 and 18 hours until request succeeds.

Check createdAt field of webhook payload to make sure that you're getting relevant applicant status.

We recommend that you wait for the webhook no more than a day, and then send a request to our server for information about the status of the applicant.

Also you can monitor webhook statuses and resend them manually on the API Health page of dashboard.

Please note that the rejectLabels are only needed to analyze your statistics. They are generalized, so you should not use them to generate comments for your end user.

Webhook contains a reviewResult field that contains extra information, please see example. An important field is reviewAnswer, which contains a final highly trusted answer. Additionally, in cases of the RED answer, the rejectLabels field contains one or more of the following machine-readable constants:

# Applicant life-cycle

When creating an applicant, its status becomes init.
After uploading all required documents the status becomes pending.

Automatic status change (to pending) only works within our SDKs and when all necessary documents are uploaded.

Within API Integration there is a special mode, when a client must manually signal to us when an applicant is ready to be reviewed.
After the verification process is completed, the status of the applicant will change to completed.

# Getting applicant status (SDK)

It is recommended that you use this method if you are using WebSDK or MobileSDK since SDKs will show rejection reasons and comments within their screens. But if you still need to fetch rejection comments, it's possible using method below.

GET /resources/applicants/{applicantId}/status

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID

# RESPONSE

Name	Type	Optional	Value
createDate	Date	No	Date of creation of the applicant.
reviewDate	Date	No	Date of check ended.
startDate	Date	No	Date of check started.
moderationComment	String	Yes	A human-readable comment that can be shown to the end user.
clientComment	String	Yes	A human-readable comment that should not be shown to the end user.
reviewStatus	String	No	Current status of an applicant.

The reviewStatus can be one of the following:

Value	Description
init	Initial registration has started. A client is still in the process of filling out the applicant profile. Not all required documents are currently uploaded.
pending	An applicant is ready to be processed.
prechecked	The check is in a half way of being finished.
queued	The checks have been started for the applicant.
completed	The check has been completed.
onHold	Applicant waits for a final decision from compliance officer (manual check was initiated) or waits for all beneficiaries to pass KYC in case of company verification.

Please note that reviewAnswer has an impact on an applicant only with reviewStatus : completed.

# Getting applicant status (API)

It is recommended that you use this method if you not only need an applicant’s status, but also information about documents.

GET /resources/applicants/{applicantId}/requiredIdDocsStatus

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID

# RESPONSE

A breakdown for each step. Each step contains an array of images' IDs (could be several, e.g., if two sides were uploaded).

In case of an applicant being rejected with FINAL value of reviewRejectType within webhook payload or at the answer on that endpoint response from requiredIdDocsStatus may not have a lot of sense. If you'd like to fetch moderationComment or clientComment on FINAL rejection better to get it from webhook or applicant data payload.

You can get images with IDs from response by issuing a request described here.

# Requesting an applicant check

You can programmatically ask us to re-check an applicant in cases where you or your user believe that our system made a mistake, or if you're sending us documents via API and would like for us to perform a check. To do it you should explicitly move an applicant to the pending state by performing the following request.

POST /resources/applicants/{applicantId}/status/pending?reason={reason}

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID
reason	String	No	Status change reason

Provide a reason if available. It will help us understand why you want to recheck an applicant. If agreed in advance the reason you will be sending, we can automate the process and e.g., perform some additional checks and notify you about the results by the usual webhook means. If you want to automate complaints to your support, just send a user message along, and we will consider it on a case-by-case basis.

# RESPONSE

In case of HTTP response 200, you may ignore the response body.

# Example request

Copy
curl -X POST \

# Requesting an applicant check with different verification type

If you plan to use this endpoint, please inform the Sum&Substance team, because this requires certain settings on our side.

You can programmatically request applicant check with flow that somehow differs from your usual checks.

POST /resources/applicants/{applicantId}/status/pending?reasonCode={reasonCode}

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID
reasonCode	String	Yes	Code of the new flow

Provide us a reasonCode, so we could set up different flows on our side.

# RESPONSE

In case of HTTP response 200, you may ignore the response body.

# Example request

Copy
curl -X POST \
  'https://api.sumsub.com/resources/applicants/5b73b82f0a975a3b46429758/status/pending?reasonCode=wlCheck'

# Example response

Copy
{
  "ok": 1
}

# Getting document images

Since a user may re-upload images several times and, for example, also change a passport photo to an ID card, it might be tricky for you to understand which ones actually made the applicant pass or fail.

If you are interested in receiving images that were part of the final verification, you should use this method.

GET /resources/inspections/{inspectionId}/resources/{imageId}

# REQUEST ARGUMENTS

Name	Type	Required	Description
inspectionId	String	Yes	Inspection ID (it's a part of an applicant)
imageId	String	Yes	Image ID (see above)

# RESPONSE

Binary content representing a document. The Content-Type response header more precisely describes the response mime-type. The full list of mime-types and file formats you can find here.

# Example request:

Copy
curl -X GET \
  'https://api.sumsub.com/resources/inspections/5bb8cca10a975a624903cf66/resources/551262049'

# Adding an applicant to blacklist

If for some reason you need to add an applicant to the blacklist, you can use this endpoint. It is necessary to add the reason for adding the applicant to the blacklist.

POST /resources/applicants/{applicantId}/blacklist

We advise checking if the applicant is not already in our blacklist first (check for BLACKLIST value within rejectLabels[] array of that applicant). In case you'll try to add a blacklisted applicant to blacklist again we'll throw a 400 http status with 5000 error code.

# REQUEST ARGUMENTS

Name	Type	Required	Description
applicantId	String	Yes	Applicant ID
note	String	Yes	Reason or note for the applicant added to the blacklist (URL encoded)

# RESPONSE

The answer will contain the applicant added to the blacklist.

# Example request

Copy
curl -X POST \
  'https://api.sumsub.com/resources/applicants/5c0e93c30a975a53a79aa54b/blacklist?note=A%20user%20provided%20a%20fake%20document'

Sharing Flow

Sometimes our clients partner with each other and want to simplify and speed up verification for their users when they have passed KYC once via Sum&Substance.

Assume a user A passed KYC in service X, and is now registering at the partner service Y. If X agrees to share information about A with Y, it can be done as follows:

X generates a share token and passes it to Y
Y calls our API with the share token and receives an applicant for user A (with all its data and documents) on their account

POST /resources/accessTokens/-/shareToken?applicantId={applicantId}&forClientId={clientId}

# Example of getting a share token (done by `X`)

Copy
## applicantId and Y's client ID must be provided

Name	Type	Required	Description	Default
applicantId	String	Yes	Applicant ID on service `X`
forClientId	String	Yes	Client ID of service `Y` (ask them for this information). You can find your `clientId` at the dashboard in the applicant profile - field of "Created for" and at response of getting applicant data request - `clientId`

trustReview	Boolean	No	If you trust your partner's check result, then you should use `true`. If it is `false`, then the applicant will be rechecked.	`false`

# RESPONSE

Applicant entity in service Y. Note a new applicant ID will be returned to the response. Bind it in your system as needed.

Please note that share tokens will be invalidated once used.

# Resetting an applicant

In very rare cases, it is required to change the status of the applicant to init. For example, if a user has contacted support with a request to re-pass verification from scratch with new documents.

Please note that we're not allowing reset applicants that were rejected for fraudulent activities. That endpoint will throw a 400 http status if applicant has one of these rejectLabels: FORGERY, SELFIE_MISMATCH, BLACKLIST, INCONSISTENT_PROFILE, FRAUDULENT_PATTERNS.

If you plan to use this endpoint, please inform the Sum&Substance team, as we may be able to suggest another flow for your case.

# Webhooks

A webhook is an HTTP POST request sent to a target you define at Dev space dashboard.

Please note that we do not send any info to endpoints using http, only https.

Not receiving an answer from webhook endpoint for more than 15 seconds will be considered as a timeout, and our service will try to resend that webhook again later.

The test server does not automatically check the applicants. If you need to change the status of the applicant or get webhook on the test server, you can do it by yourself.

Please note that there is a limit on the webhook number: 20 webhook objects max.

We can send webhooks not only via HTTP request, but also as notifications in Slack, Telegram or via email.

# Webhook types

The types of webhooks we send depend on the settings.

Value	Description
applicantReviewed	When verification is completed. Contains the verification result. More information about this type of webhook can be found here.
applicantPending	When a user uploaded all the required documents and the applicant's status changed to pending.
applicantCreated	When an applicant is created.
applicantOnHold	Processing of the applicant is paused for an agreed reason.
applicantPersonalInfoChanged	Applicant's personal info has been changed.
applicantPrechecked	When primary data processing is completed.
applicantDeleted	Applicant has been permanently deleted.
videoIdentStatusChanged	Status of Video Ident type of verification has been changed.

If you're not receiving webhooks from us try to check your endpoints first with SSL Labs or Docker.

# Verifying webhook sender

It's better to not rely on our IP addresses for whitelisting them as webhook sender because they're changing from time to time.

In order to make sure that a webhook is sent by us, we have the possibility to sign it with the HMAC Sha1Hex algorithm.

If you want to utilize this feature, set a Secret Key value for each webhook via dashboard.

To verify that a webhook is sent by us

Get a webhook x-payload-digest header value and payload as it is without any alteration or converting to json.
Convert the HTTP webhook body into bytes.
Perform calculations on your side to create a digest using Secret Key, raw webhook payload in bytes and HMAC Sha1Hex algorithm.
Compare x-payload-digest header value with calculated digest.

In order to check that you compute the digest the same way we do, you can call the following endpoint.

POST /resources/inspectionCallbacks/testDigest?secretKey={secretKey}

# REQUEST ARGUMENTS

Name	Type	Required	Description
#{body}	Object	Yes	Any payload
secretKey	String	Yes	A secret key that might be used for signing

# RESPONSE

Value	Description
digest	Result of the calculation

Please test your webhook before sending its URL to us. At a minimum, it should not give a 500 HTTP response or require any sort of authorization.

# Example request to get digest

Copy
curl -X POST \
  'https://api.sumsub.com/resources/inspectionCallbacks/testDigest?secretKey=SoMe_SeCrEt_KeY' \
