Creates an instant funding request. The request will be processed and the funds will be made available to the account in the form of a Memopost non trade activity. Upon settlement the Memoposted will be corrected to a CSD activity.
Idempotency: When the Idempotency-Key header is supplied, this endpoint is idempotent. Multiple requests with the same key and identical request body will create only one transfer. A subsequent request returns the previously created transfer with the same response (no duplicate is created). If the same key is used with a different request body, the API returns 422 Unprocessable Entity.
Recommended for production: Always supply Idempotency-Key when creating transfers. This allows safe retries on timeouts, network errors, or 5xx responses without risking duplicate transfers. Use a client-generated unique value (e.g. UUID).
Headers
Unique key for idempotent create. When supplied, duplicate requests (same key and body) return the original transfer instead of creating a new one. Use a client-generated value (e.g. UUID) per logical transfer. Strongly recommended for production to prevent duplicate transfers on retries.
Request body
Response
Instant transfer request created.
