01-PII Verify Success (Natural Person / Pre-Transaction)
- Pre-Transaction Approval - PII Verification for Natural Person beneficiary (KYC).
- GTR will send three consecutive callback requests: address verification (
callbackType=6), PII verification with encrypted KYC payload (callbackType=4), and TXID update notification (callbackType=7). - Your server should decrypt the PII payload, verify the Natural Person fields, and return successful verification results with all
verifyFieldshaving status 1 (matched).

- Method:
POST - Your Callback Endpoint:

callbackType: 6→ Address Verification,callbackType: 4→ PII Verification,callbackType: 7→ TXID UpdateverificationDirection: 2indicates Pre-Transaction scenario (beneficiary data verification)- Do NOT use the
tickerfield to search for users - PII payload requires decryption using your private key with Curve25519
- The same
requestIdis used across all three 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: Address Verification Success
When the address is found in your system, you should return:
verifyStatus: 100000 (success)
{
"verifyStatus": 100000,
"verifyMessage": "Address 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": "Natural Person KYC verification passed",
"verifyFields": [
{
"type": "110026",
"status": 1,
"message": "name matched"
},
{
"type": "110025",
"status": 1,
"message": "dateOfBirth matched"
},
{
"type": "110045",
"status": 1,
"message": "address matched"
}
]
}
}
Stage 3 Response: TXID Update Acknowledgment
When the TXID update is received, you should return:
verifyStatus: 100000 (success)
{
"verifyStatus": 100000,
"verifyMessage": "TX ID update received successfully"
}
Test Validation
Success Criteria:
- ✅ All three callback stages handled successfully
- ✅ Each callback responds within 30 seconds
- ✅ HTTP status code 200 returned for all stages
- ✅ Address verification returns
verifyStatus: 100000 - ✅ PII decryption and Natural Person KYC validation successful
- ✅ KYC field validations return matched results (110026, 110025, 110045 all status: 1)
- ✅ TXID update properly recorded in your system
Common Issues:
- ⚠️ PII Decryption: Must properly decrypt the
securedPayloadusing Curve25519 with your private key - ⚠️ KYC Validation: Validate Natural Person fields (name, dateOfBirth, address) according to IVMS 101 standards
- ⚠️ Stage Sequence: Handle callbacks in the correct order; maintain request state across multiple callbacks
- ⚠️ Ticker Reference: Do NOT use the ticker field to search for users
