partner
POST /v1/partner/customers/{externalId}/holder-verifications/{caseId}/documents
Upload one holder document for your customer (PDF, JPEG or PNG, 10 MB at most).
Authentication
Send an API key as a bearer token. The key must carry the partner.domains permission; a key without it is refused with 403, not 404.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X POST https://api.zinndigital.com/v1/partner/customers/{externalId}/holder-verifications/{caseId}/documents \
-H "Authorization: Bearer zdk_live_…"Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
