Callback Event

After a customer successfully completes a payment through any supported provider, the system will send a GET request to your callback URL. This callback includes all the parameters you originally supplied, along with several additional fields containing the payment result details.

Request Parameters

value_coin: The actual amount of USDC received from the provider.

coin: The payout currency (usually polygon_usdc or polygon_usdt).

txid_in: The Polygon transaction ID showing the provider’s deposit into the temporary order wallet.

txid_out: The transaction ID for the instant payout sent from the temporary wallet to your merchant wallet.

address_in: The unencrypted temporary receiving wallet address. This should match the polygon_address_in value that you obtained during the initial create wallet step.

These fields allow you to verify the payment, confirm the currency used, and trace both inbound and outbound blockchain transactions for full transparency.
