Overview

This page documents the POST /transfer/open/institution/v1/pay/charge endpoint. The full schema, parameters, and examples are rendered from the linked OpenAPI definition above.

​
Notes

  • Authentication uses the standard GatePay signed headers.
  • This dedicated institution endpoint requires X-GatePay-On-Behalf-Of, which identifies the initiating account for this charge and can be either an institution account ID or a sub-account ID.
  • In the request body, accountId means the payer account ID (the debited account).
  • In the current version, this endpoint returns the final execution result synchronously and no longer requires status polling through the detail endpoint.
  • For shared signing rules, see /api-reference/version/100/en/common/securityAndSignature.
