Authentication

X-API-Keystring · headerrequired

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

Use this endpoint to create a subaccount. 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

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.
