Setting Up Gateway Modules
Payment gateways can be configured in Setup > Payment Gateways. Each gateway has their own specific API requirements in order to process transactions so they will vary from gateway to gateway. However, all gateways have 3 core options:
- Show on Order Form – Checking this box will mean it can be shown on the order form as an option – subject to product group gateway restrictions
- Visible Name – The name that is used for this gateway throughout the system and to clients (eg. gateway can be Authorize.net, visible name might be Credit Card)
- Convert To For Processing – This option is for when using multiple currencies. It is possible that not every gateway you use will accept all the currencies you offer on your site and so for those that don’t, you can choose a currency here for WHMCS to convert to before sending to them. For example if using Google Checkout with a UK account but offering prices in GBP & USD, you would need to select GBP in the Convert To box. This will use the rates set in Config > Currencies to do the conversion which can be set to auto update daily.
Supported Gateway Modules
The following is a list of all the payment gateways that are included in WHMCS by default. Merchant Gateways store credit card information securely in the WHMCS database whilst Third Party Gateways take the client to the provider's website to process payments off-site. Tokenisation Gateways are a happy medium where repeat billing is possible by storing the original transaction details or a reference number, not the full credit card number, thus reducing your PCI liabilities.
The type of payment gateway selected influences which invoice notification email template it sent; Third Party Gateways will send the "Invoice Created" email template, whilst Merchant and Tokanisation Gateways will send the "Credit Card Invoice Created" email template. This allows you to customise the payment instructions to client s for the different payment processes.
Any gateways showing in blue below indicates further information relating to the setup & use of that gateway is available by clicking on the name.
It is also possible to create your own gateway modules for WHMCS should you want to integrate with a gateway that isn't offered by default. Please refer to our Developer Resources section for more details.

Deactivating Gateway Modules
Should you no longer wish to use a particular payment gateway clicking the red (Deactivate) link beside the name will gracefully remove the gateway from the system. This will prevent any further payments being made using this gateway and automatically reassign any products/services/invoices assigned to that payment method to another option. Upon clicking the deactivate link, a popup window will appear prompting for the selection of the alternative payment gateway to which any currently assigned items should be changed to.
Test Credit Card Numbers
Gateways often have test modes where you can use test card numbers. The common test card numbers are below and should generate successful test transactions but they can vary from gateway to gateway. You may use any expiration date in the future.
