Callback - Network Health Check

This callback is a simple network connectivity test that GTR uses to verify your service is reachable and responsive.

The callback is triggered periodically by GTR to ensure your endpoint is healthy and can receive Travel Rule requests.

When GTR performs a network health check, you will receive a callback request with callbackType=0.

Request & Response

You can expect the following request from GTR.

{
  "requestId": "[REQUEST-ID]",
  "invokeVaspCode": "[YOUR_VASP_CODE]",
  "originatorVasp": "[YOUR_VASP_CODE]",
  "beneficiaryVasp": "[YOUR_VASP_CODE]",
  "callbackType": 0,
  "callbackData": {}
}

Upon receiving this, you can simply respond with verifyStatus=100000.

GTR expects to receive response from your service within 2 seconds.

{
  "verifyMessage": "success",
  "verifyStatus": 100000
}
