How to Integrate with WHMCS

There are 2 ways to integrate WHMCS with Xendit:

• From GitHub repository: https://github.com/xendit/xendit-whmcs/releases
• From WHMCS Marketplace: https://marketplace.whmcs.com/product/6411-xendit-payment-gateway

How to Integrate from GitHub Repository

1. Go to GitHub repository, and download the latest version.
2. Extract the zip file and you will see the folder name modules.
3. Copy folder modules to the root WHMCS directory

• Copy modules/gateways/xendit to your <root directory>/modules/gateway
• Copy modules/gateways/callback/xendit.php to your <root directory>/modules/gateways/callback

4. Verify the folder is copied correctly

• Go to modules/gateways and check the folder xendit and file xendit.php are already there
• Go to modules/gateways/callback and check file xendit.php is already there

5. Activate the Xendit module

• Login to the admin dashboard
• Go to System settings > Payment Gateways > All Payment Gateways
• Activate Xendit Payment Gateways

6. Xendit Payment Settings
   On the Payment Gateways page, click in the tab Manage Existing Gateways and fill in the input Public key/Secret key. Get your API keys from here.

• API Secret Key Permission:
  • Money in: WRITE
  • Money out: NONE
• You can choose to enable Test Mode for testing.
  Note: for test mode, use the API keys from your Test mode Xendit account. For live transactions, use your API keys from your Live mode Xendit account.

7. Verify on the checkout page
   Now you can try to add a product to your cart and go to the checkout page to see if the Xendit Payment Gateway is enabled.

Optional: Firewall Whitelisting

If you happen to use firewall, there's an optional step, which is to whitelist Xendit Callback URLs in order to avoid unreceived callback:

• WHMCS: <merchant_site>/modules/gateways/callback/xendit.php

You can input these URLs when creating firewall rules. Example below is the display if you're using Cloudflare:
