Upload a financial file

POST

/v1/files/financial-document

Use this endpoint to upload financial documents of a user, requested by Bitpanda as proof of funds or proof of wealth.
Each document is attached to the case provided by Bitpanda (appian_case_id). When a case requires multiple documents, upload them one per request, using document_number to indicate the position of the document (starting at 1) and documents_count to indicate the total number of documents for the case.

Unlike Upload a file, no file id is returned, as financial documents are not referenced in other endpoints.

The following purposes are permitted:

proof_of_funds - evidence of the origin of the funds used by the user

proof_of_wealth - evidence of how the user's overall wealth has been accumulated

The document name must be maximum 125 characters long. The file should have a maximum of 20 megabytes.

The following MIME types are permitted for both purposes: application/pdf, image/jpeg, image/png.
