Testing Callback

Sandbox supports automatic callbacks. For production callback setup, contact Transafe support.

Callback Rules

Collection auto-callbacks succeed. For payout, if the last digit of request parameter phone is odd (1/3/5/7/9), the callback is success.
For payout, if the last digit of phone is even (0/2/4/6/8), the callback is failure.

Mechanism

After create collection/payout requests, the system usually sends an automatic callback within 1–2 minutes.
If you do not receive callbacks, use a request-bin style tool such as requestbin for debugging. If you still receive nothing, contact Transafe support.
