Notes

  • Institution requests must include X-GatePay-On-Behalf-Of to indicate the initiating account context for the delegated request.
  • For shared signing rules, see /api-reference/version/100/en/common/securityAndSignature.

​
Institution Notes

  • Institutional requests must include X-GatePay-On-Behalf-Of to specify the institutional sub-account to operate on.
