# Operation Descriptor Generator API The Operation Descriptor Generator API (v1.0) from Khipu allows merchants to create a unique operation identifier along with an encrypted descriptor for initiating new bank transfer operations. Using a single endpoint (POST /v1/descriptor/payment), you submit the origin bank ID and detailed transaction parameters—like transfer amount, currency, payer information, and recipient account details. On a successful call, the API returns a JSON object containing an operation.id (a UUID) and an operation.description field: a Base64‑encoded encrypted descriptor designed for use in secure bank transfer flows. Authentication is handled via the x-api-key header.
