07-PII Verify Success (Legal Person / Post-Transaction)
- Post-Transaction Approval - PII Verification for Legal Person originator (KYB).
- GTR will send two consecutive callback requests: TX verification (
callbackType=9) and PII verification with encrypted KYB payload (callbackType=4). verificationDirection: 1indicates Post-Transaction scenario where the originator data is verified.- Your server should decrypt the PII payload, verify the Legal Person fields, and return a successful verification. At minimum, the originator legal person name field (
101001) must be reported inverifyFieldswithstatus1 (matched). - When responding, the returned IVMS payload should carry three sections —
Originator,Beneficiary, andBeneficiaryVASP(the counterparty's VASP block). Keep the incomingOriginator,Beneficiary, andBeneficiaryVASPblocks as received.

callbackType: 9→ TX Verification,callbackType: 4→ PII VerificationverificationDirection: 1indicates Post-Transaction scenario (originator data verification)- Post-Transaction uses field codes in the
101xxxseries (originator Legal 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 Legal Person KYB is successfully verified, you should return:
verifyStatus: 100000 (success) —verifyStatusandverifyMessageare top-level fields,verifyFieldsis nested insidedata.verifyFieldsshould include at least the originator legal person name field (101001) withstatus1 (matched). Additional fields such ascountryOfRegistration(101022) orgeographicAddress(101003) are accepted but not required.
{
"verifyStatus": 100000,
"verifyMessage": "Post-Transaction Legal Person KYB verification passed",
"data": {
"verifyFields": [
{
"type": "101001",
"status": 1,
"message": "originator legalPersonName matched"
},
{
"type": "101022",
"status": 1,
"message": "originator countryOfRegistration matched"
},
{
"type": "101003",
"status": 1,
"message": "originator geographicAddress matched"
}
]
}
}
Note: The data field is required (must be present and non-null). GTR will also accept verifyStatus values 100002 (pending/async) or 200003 (PII verify fail).
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 Legal Person KYB validation successful
- ✅ Post-Transaction KYB field validation returns matched result — at minimum the originator legal person name field (
101001) withstatus: 1
Common Issues:
- ⚠️ PII Decryption: Must properly decrypt the
securedPayloadusing Curve25519 with your private key - ⚠️ Field Code Series: Post-Transaction uses
101xxxseries (originator Legal Person), not111xxx(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
- ⚠️ Three IVMS Sections Required in Response: The response payload should carry
Originator,Beneficiary, andBeneficiaryVASP(the counterparty's VASP block) — keep them as received. Even though the field-level verification target is only theOriginator(Legal Person), theBeneficiaryperson block must still ship out end-to-end so both regulators can trace the full counterparty picture.
