API v2 to v3 migration guide

Start here

The following guide is designed to help you migrate from Onfido API v2 to API v3.

Our API reference website now defaults to new comprehensive documentation on API v3 which you can review.

You can also go to our API reference to find out about our supported client libraries in API v3.

Skip to a comprehensive table of endpoint mappings from v2 to v3.

If you have any difficulties migrating, please email our Client Support team.

Authentication

Authentication is exactly the same in API v3. You'll still use the same API tokens and base URLs, and the sandbox and live environments are configured in the same way.

Read more about token authentication in our API reference.

Summary of differences

The following sections detail differences in API v3 compared to v2, which you should consider when migrating.

Applicant creation

In the request body when creating an applicant, the following fields no longer exist:

gender

telephone

mobile

country (now solely within address)

mothers_maiden_name

previous_last_name

nationality

country_of_birth

town_of_birth

addresses (has become address - read more in the following section of this guide)

An example of a valid API v3 request body for creating an applicant is:

    {
      "first_name": "Jane",
      "last_name": "Doe",
      "dob": "1990-01-31",
      "address": {
          "building_number": "100",
          "street": "Main Street",
          "town": "London",
          "postcode": "SW4 6EH",
          "country": "GBR"
        }
    }

You can review the new form of the applicant object.

Applicant addresses

addresses has become address, and is now a single address rather than an array of addresses. The country field within address is the only place you need to provide information about an applicant's country of residence.

In API v3, only a single address can be provided, not a list of past addresses.

"Applicant provides data" replaces standard checks

API v3 has no concept of "standard" and "express" checks.

If you previously used express checks in v2, you no longer need to pass a type in check creation requests.

If you previously used standard checks to gather applicant information with the applicant form, simply set applicant_provides_data to true.

Asynchronous checks are the default

In API v3, async has changed to asynchronous and is set to true by default. If set to false, report results in the check request response will only be returned when all reports are complete. You can configure webhooks to notify you when the report is complete.

Documents

Documents are no longer nested under the /applicants resource. They're now managed under /documents.

Document uploads

The new endpoint is POST /documents/ and you should provide an applicant ID in the request body to associate a document with an applicant.

Facial Similarity score

The score value is now returned in the properties object under the new face_match sub-breakdown. You can read more in our API documentation.

Identity reports

identity_enhanced reports replace all Identity reports in API v3. They do not support previous addresses.

Report type groups

Report type groups do not exist in API v3. Instead, we've simplified how to create a check. Read more in the section later in this guide on check creation.

Webhook event objects

The completed_at timestamp in webhook event objects has been replaced by completed_at_iso8601 (it now conforms to ISO 8601). For example:

HTTP/1.1 201 Created
Content-Type: application/json

{
  "payload": {
    "resource_type": "report",
    "action": "report.completed",
    "object": {
      "id": "<REPORT_ID>",
      "status": "complete",
      "completed_at_iso8601": "2019-10-28T15:00:39Z",
      "href": "https://api.onfido.com/v3/reports/<REPORT_ID>"
    }
  }
}

Checks in API v3

Checks are no longer nested under the /applicants resource. They're now managed under /checks.

Check creation

Check creation is designed to be much simpler in API v3.

• the new endpoint is POST /checks/
• we've removed the concept of variants and options (see the section 'Report names, options and package variants' later in this guide)
• you now simply pass report names to the report_names array of strings
• an applicant ID is now required in the request body

Example check creation (Document and Facial Similarity Photo reports):

Before (v2):

POST /v2/applicants/<APPLICANT_ID>/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "type": "express",
  "reports": [
    {
      "name": "document"
    },
    {
      "name": "facial_similarity",
      "variant": "standard"
    }
  ]
}

Now (v3):

POST /v3/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "applicant_id": "<APPLICANT_ID>",
  "report_names": [
    "document",
    "facial_similarity_photo"
  ]
}

Example check creation (Identity Enhanced report):

Before (v2):

POST /v2/applicants/<APPLICANT_ID>/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "type": "express",
  "reports": [
    {
      "name": "identity",
      "variant": "kyc"
    }
  ]
}

Now (v3):

POST /v3/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "applicant_id": "<APPLICANT_ID>",
  "report_names": [
    "identity_enhanced"
  ]
}

Example check creation (Watchlist Enhanced report):

Before (v2):

POST /v2/applicants/<APPLICANT_ID>/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "type": "express",
  "reports": [
    {
      "name": "watchlist",
      "variant": "kyc"
    }
  ]
}

Now (v3):

POST /v3/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "applicant_id": "<APPLICANT_ID>",
  "report_names": [
    "watchlist_enhanced"
  ]
}

Example check creation (Right to Work report):

Before (v2):

POST /v2/applicants/<APPLICANT_ID>/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "type": "express",
  "reports": [
    {
      "name": "right_to_work"
    }
  ]
}

Now (v3):

POST /v3/checks HTTP/1.1
Host: api.onfido.com
Authorization: Token token=<YOUR_API_TOKEN>
Content-Type: application/json

{
  "applicant_id": "<APPLICANT_ID>",
  "report_names": [
    "right_to_work"
  ]
}

Report names in API v3

The concept of package variants and options for reports does not exist in API v3. The same functionality is achieved using more descriptive report names.

Report names: v2 -> v3 mapping

You'll find a very similar table in our API reference documentation.

Endpoints: v2 → v3 mapping

The following table lists endpoint mappings from v2 to v3 in full. Any unlisted endpoints are unchanged:

• RTG = Report type group
