API Documentation

/documents (upload)

Upload supporting documentation for a KYC verification.

Suggest Edits

👍

This doc has been updated for Priority specifications.

During the KYC process, documentation may be needed to verify an end user and pass them successfully through KYC or KYB. The verification status will transition to documents_required.

Use the tags (if you're using Classic KYC) or the reasons (if you're using Advanced KYC) to determine the type of doc to be uploaded. These are returned by /check_kyc (Classic) or /get_verifications/verification_uuid (Advanced).

There are two options for structuring your uploads. You can either upload a single document at a time, or use a structure that allows for multiple documents in a single upload.

If using the Single Document request format, you will need to make two calls per document: one for the front, and one for the back.

📘

Good To Know

  • Priority estimates an approximately 24-hour turnaround time to review uploaded docs.
  • Only driver's licenses and state ID's require a front and back image. Otherwise, only the front is required.

Requests

Authorization / Authentication

Apps using Access Token Authorization

Use a valid access token in a Authorization: Bearer request header.

See Authenticating with an Access Token for more details.

Apps using ECDSA Authentication

Both authsignature and usersignature headers are required for this request. The usersignature header should be generated with a keypair registered to the user (either registered from the /register endpoint or the /register_wallet endpoint).

See the section on ECDSA Authentication for more detail about ECDSA signature generation.

Requirements

  • NOTE: Content-Type is different from all other endpoints. Set to multipart/form-data
  • NOTE: Document URL's are not supported. This endpoint requires you send a locally stored document
  • Maximum request size is 20 mb

📘

Handling the multipart/form-data boundary value

NodeJS
Do not manually set Content-Type, as this will not include a 'boundary.' Let your request package automatically detect the content type so that it can automatically generate a boundary.

Python
multipart/form-data is the default Content-Type for the python requests module; when using that module, don't set the header's Content-Type, but instead let the requests module use its default, and it will properly determine the multipart/form-data boundary value for you.

Single Document

Make two calls per document, one for the front and one for the back.

  • Only driver's licenses

Multiple Documents

Upload multiple documents in a single request. Can be used to upload a single document, front and back both, in a single request.

  • files: the files you wish to upload. These must be in binary format, URLs are not supported
  • data: the header information and the file_metadata
  • file_metadata: the document metadata for each file you are uploading

🚧

Labels must match!

The labels you use in the "files" section must match the ones used in the "file_metadata" section.
