Notifications

Important Notes

1. Notification URLs can be configured during merchant onboarding or via the notifyUrl parameter in transaction requests.
2. The notifyUrl parameter takes precedence. If neither is provided, notifications will not be sent.
3. Payment results must be determined by webhook notifications. Do not rely solely on the status field in synchronous responses!

Signature Verification Steps

1. Exclude parameters marked as No in the Signature column. See Parameters Excluded from Signature.
2. Sort remaining non-empty parameters by key in ASCII order, concatenate values, and append your merchant secret key.
3. Generate SHA-256 hash of the resulting string.
4. After successful verification, return only the transactionId value.

Note

• Future webhook parameters will participate in signature verification by default
• Always exclude parameters marked as No dynamically rather than hardcoding a list of Yes parameters to prevent signature failures when new fields are added
