/documents

Upload supporting documentation for KYC

During the KYC onboarding process, it may be necessary to upload supporting documentation. This endpoint will support the upload of images of that documentation.

Requests

The request body at this endpoint is the header_msg JSON object.

header.user_handle should have the registered handle to be verified.

Both authsignature and usersignature headers are required for this request.

Content-Type

  • multipart/form-data

❗️

Content-Type differs from most of the other endpoints.

This endpoint is one of very few which does not have a Content-Type of application/json.

📘

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.

Uploading a single document

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.

Single document format:
Driver's license example - requires 2 uploads and 2 separate calls (front and back):
/documents request for front:

},
...
  "mime_type": "image/jpeg",
  "document_type": "id_drivers_license",
  "description": "front of driver's license"

/documents request for back:

🚧

WARNING

  • document URL's are not supported. The /documents endpoint requires that you send a locally stored document
  • Maximum request size is 20mb.

Uploading multiple documents in a single request

Multiple documents can be uploaded in a single request by using a different request format. This format can also be used to upload a single document if desired.
"files" will be the files you wish to upload. These must be in binary format, URLs are not supported.
"data" will contain the header information and the "file_metadata".
"file_metadata" is the document metadata for each file you are uploading.

🚧

Labels must match!

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