Integrate the Transaction Verification API and Balance Inquiry API under [Common APIs].
5.
Check [Payment of Video Case] to understand the practical use cases of each API.
2
Integration Testing

Use the examples in [Transaction APIs] to test the corresponding payment scenarios.
2.
For callback testing, contact customer support to assist with mock callback validation.
3
Production Preparation

Provide the all list of production IP addresses for us to whitelist.
2.
Add our callback IP addresses to your whitelist.
3.
Ensure secure distribution of API keys; contact us if you need to update the key.
4.
Enable 2FA binding for your Dashboard admin account.
5.
Notify us when going live in production so we can help monitor data and verify the integration.

4. Fee Description#

Our platform charges transaction fees instantly for each order (fees are applied per completed transaction), rounded up to two decimal places.
Example: For an order amount of 99 with a 0.6% fee, the total fee charged will be 0.60 instead of 0.59.
