Use this POST request to send the user's identifiers (for example, images of document - front/back, selfie image, liveness video) for validation.

This API supports uploads for the following merits:

File Requirements

Image Files

Image files (such as document photos and selfies) must have at minimum resolution of 600x600 pixels with a maximum file size of 50MB. The following is a list of supported image file formats:

*.jpg
*.jpeg
*.png
*.pdf — exclusive to custom documents & Bank Account Statements

Video Files

MP4
WebM
QuickTime (*.mov)
3GP (*.3gpp)
X-Matroska (_.mkv,_.mk3d, _.mka, _.mks )

Document Handling

📘
One-Sided Document Handling
The API can handle both one- and two-sided documents.

If a user only sends the front of a one-sided document, MetaMap will immediately start the verification process

If a user only sends the front of a document that may have one or two sides, MetaMap will wait 10 minutes for the image of the document back before starting the verification process with only the front.

You can use the Skip Verification Upload Wait Time API for documents that may have one or two sides to skip the 10 minute wait time.

For a list of countries whose documents have one side, two sides, or one or two sides, go here.

Request Body Requirements

The body parameters should be in type form.
The JSON inputs must match the flow configuration order on your MetaMap Dashboard for both documents and biometric requirements or you will not be able to send this request.
- The merits that use the Send User Identifiers API use the following order of precedence in every metamap:
  1. Document Verification
  2. Biometric Verification
  3. Custom Document
  4. Bank Account Data
- The first document of the first merit must have a group number starting at 0. Additional documents must be assigned separate incremental group numbers in order of appearance in the metamap.
