## 3. Activate Integrated Payment Methods

- For certain payment methods, PayerMax will file the application with the payment channel on your behalf. Transactions can only be processed after the filing is approved. You cannot launch full traffic during the approval period.

- You can log in to the [Merchant Portal (MMC)](https://mmc.payermax.com/#/login) and check the availability status of payment methods under **Contract Management** → **Payment Method Availability Inquiry**.

## 4. Set Server IP Whitelist

If your integration and testing network has security restrictions on access IP whitelists, please contact PayerMax Technical Support to obtain the PayerMax server IP addresses and add them to your whitelist. Otherwise, PayerMax will not be able to initiate calls to your [configured callback address](https://docs.payermax.com/en/202606-version/acquiring/start-integration/golive-confirmation.md#_2-configure-production-environment-integration-information) properly.
