Authentication

X-API-Keystring · headerrequired

Use the ky_... key created under Integrations → API Keys in the KyvoPay dashboard.

Use this endpoint to perform this operation. For safe retries, reuse the same idempotency key for the same business operation.

Request

Note

Private endpoints require the X-API-Key header. Keep credentials on your backend and log the response request_id for diagnostics.

Response

The response uses the standard data, error and request_id envelope.

Implementation notes

  • Validate required input before sending the request.
  • Store returned public identifiers without assuming their format.
  • Treat 4xx validation errors as non-retryable until the request is corrected.
  • Retry timeouts, 429 and temporary 5xx responses with exponential backoff.
  • Keep the idempotency key stable across retries.
