05-PII Verify Success (Natural Person / Post-Transaction)
- Post-Transaction Approval - PII Verification for Natural Person originator (KYC).
- GTR will send two consecutive callback requests: TX verification (
callbackType=9) and PII verification with encrypted KYC payload (callbackType=4). verificationDirection: 1indicates Post-Transaction scenario where the originator data is verified.- Your server should decrypt the PII payload, verify the Natural Person fields, and return successful verification results with all
verifyFieldshaving status 1 (matched).
GTR Request Sequence (GTR → VASP)
- Method:
POST - Your Callback Endpoint:
https://[YOUR_CALLBACK_URL] - Authentication:
- mTLS (Mutual Transport Layer Security) - GTR will authenticate using client certificates

callbackType: 9→ TX Verification,callbackType: 4→ PII VerificationverificationDirection: 1indicates Post-Transaction scenario (originator data verification)- Post-Transaction uses field codes in the
100xxxseries (originator Natural Person) - Do NOT use the
tickerfield to search for users - PII payload requires decryption using your private key with Curve25519
- The TXID should already exist in your system for verification
- The same
requestIdis used across both stages - Your server should respond within 30 seconds for each callback

Expected Response Sequence (VASP → GTR)
Your server should respond within 30 seconds for each callback. All responses should return HTTP Status Code 200.
Stage 1 Response: TX Verification Success
When the TXID is found in your system, you should return:
verifyStatus: 100000 (success)
{
"verifyStatus": 100000,
"verifyMessage": "Transaction verification passed"
}
Stage 2 Response: PII Verification Success
When the Natural Person KYC is successfully verified, you should return:
verifyStatus: 100000 (success)- all
verifyFieldshavestatus1 (matched)
{
"data": {
"verifyStatus": 100000,
"verifyMessage": "Post-Transaction Natural Person KYC verification passed",
"verifyFields": [
{
"type": "100026",
"status": 1,
"message": "originator name matched"
},
{
"type": "100025",
"status": 1,
"message": "originator dateOfBirth matched"
},
{
"type": "100045",
"status": 1,
"message": "originator address matched"
}
]
}
}
Test Validation
Success Criteria:
- ✅ Both callback stages handled successfully
- ✅ Each callback responds within 30 seconds
- ✅ HTTP status code 200 returned for all stages
- ✅ TX verification returns
verifyStatus: 100000 - ✅ PII decryption and Natural Person KYC validation successful
- ✅ Post-Transaction KYC field validations return matched results (100026, 100025, 100045 all status: 1)
Common Issues:
- ⚠️ PII Decryption: Must properly decrypt the
securedPayloadusing Curve25519 with your private key - ⚠️ Field Code Series: Post-Transaction uses
100xxxseries (originator), not110xxx(beneficiary) - ⚠️ TXID Must Exist: The TXID should already exist in your system before TX verification
- ⚠️ Ticker Reference: Do NOT use the ticker field to search for users
