Upload sole proprietorship document

Most of the Fluz API is GraphQL — file upload is the exception. When registerBusiness is called with businessStructure: SOLE_PROPRIETORSHIP, upload the supporting document through this REST endpoint first, then pass the returned URL as soleProprietorshipDocumentUrl in RegisterBusinessInput.

Endpoint

Environment	URL
Staging	`POST https://transactional-graph.staging.fluzapp.com/api/v1/file-upload/sole-proprietorship-document`
Live	`POST https://transactional-graph.fluzapp.com/api/v1/file-upload/sole-proprietorship-document`

Request

Send the document as multipart/form-data, authenticated with the same access token you use for the registration flow:

curl -X POST https://transactional-graph.staging.fluzapp.com/api/v1/file-upload/sole-proprietorship-document \
  -H "Authorization: Bearer <ACCESS_TOKEN>" \
  -F "file=@business-license.pdf"

Response

Returns the public URL of the uploaded document — see UploadSoleProprietorshipDocumentResponse:

{
  "url": "https://storage.fluzapp.com/documents/..."
}

Supply this value in soleProprietorshipDocumentUrl when submitting registerBusiness. For the full registration walkthrough, including the KYB lifecycle, see Business registration.
