Fund a Payment

Client identifier (UUID).

Client-generated unique id for this request (UUID recommended), used for end-to-end tracing. Echoed back in the X-Request-Id response header and recorded in Axiym logs — quote it when contacting support. If omitted, Axiym generates one.

Unique client-generated key to safely retry a funds-moving request (e.g. a UUID, but any unique string works). Repeating a request with the same key returns the original result instead of creating a duplicate.
