What will be transmitted in the body of the POST request for confirmation?

In the body of a POST request for confirmation, data usually is transmitted that confirms the fact of performing a certain action or consent. For example, it could be a JSON object with a unique transaction identifier, confirmation status, and additional metadata.

Example of a POST request body:

{
  "transactionId": "12345",
  "status": "confirmed",
  "timestamp": "2024-06-01T12:00:00Z"
}

This allows the server to unambiguously identify what exactly is being confirmed and to process the request correctly.
