==Setting Up Gateway Modules==

Payment gateway modules allow you to accept payments of many types directly within WHMCS.

+
You can access this feature at '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > System Settings > Payment Gateways''' or, prior to WHMCS 8.0, '''Setup > Payments > Payment Gateways'''.  
  
 +
== Activating a Payment Gateway ==
 +
 +
To activate a new payment gateway:
 +
 +
# Find the payment gateway:
 +
#* In WHMCS 8.6 and later, go to '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > [[Apps and Integrations|Apps & Integrations]]'''.
 +
#* In WHMCS 8.0 to 8.6, go to '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > System Settings > Payment Gateways'''.
 +
#* In WHMCS 7.10 and earlier, go to  '''Setup > Payments > Payment Gateways'''.
 +
# Click '''Activate'''.
 +
# Configure the payment gateway (see below).
  
−
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:
+
==Setting Up Gateway Modules==
  
−
*'''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
+
[[File:Videotutorial.png‎|center|link=https://www.youtube.com/watch?v=L0B6KbPaGKE&hd=1|Watch Video Tutorial]]
−
*'''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==
+
Each gateway has its own specific requirements in order to process transactions, which vary from gateway to gateway. However, all gateways have three core options:
  
−
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.
+
*'''Show on Order Form''' — Whether to display the payment gateway on the order form and client area, subject to product group gateway restrictions. Also controls adding new payment details via the [[Admin Area]] for merchant gateways.
 +
*'''Display Name''' — The gateway's name throughout the system and to clients (for example, an [[Authorize.net]] gateway could use the visible name ''Credit Card'').
 +
*'''Convert To For Processing''' — When using multiple gateways, some gateways may not accept all the currencies you offer on your site. 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 '''and''' USD, you would need to select GBP for '''Convert To'''. This will use the rates in '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > System Settings > [[Currencies]]''' or, prior to WHMCS 8.0, '''Setup > Payments > Currencies''', to do the conversion. You can set this to auto-update daily.
 +
** For more information, see [[Converting Invoices to a New Currency]].
  
−
Please note that for tokenisation gateways, the client will need to pay an invoice manually using their credit card details before their information is transmitted to the merchant provider and a profile is created in their systems. They then send back a token to WHMCS which will be used for managing the card detail update requests via the client area and recurring payments.
+
==Supported Gateway Modules==
  
−
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 clients for the different payment processes.
+
WHMCS includes the following payment gateways by default:
  
−
The type of payment gateway also influences the behaviour of the '''Attempt Capture''' button on the invoice page in the admin area. With Third Party Gateways the button will be deactivated as the client needs to click the payment button on the invoice to send payment. For Merchant Gateways and Tokanisation Gateways the button will be active and staff can click Attempt Capture to instantly capture payment from the client's credit card.
+
* '''Merchant Gateways''' store credit card information securely in the WHMCS database.  
 +
* '''Third-Party Gateways''' direct the client to the provider's website to process payments off-site.  
 +
* '''Tokenisation Gateways''' reduce PCI liabilities when they perform repeat billing by storing the original transaction details or a reference number and not the full credit card number. For more information, see [[Working with Tokenization]].

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.
+
For tokenisation gateways with the '''Remote Update Card''' feature, clients can enter their card details via the WHMCS Client Area. This is done via an interface that the payment gateway hosts directly or by paying an invoice. This creates a profile in the payment gateway's system that returns a token.  
  
−
===Merchant Gateways===
+
WHMCS uses this to manage the card detail update requests via the Client Area and recurring payments. This does not store the full card details on your server, and some token gateways never touch it.

===Tokenisation Gateways===

Tokenisation gateways store a token to use for processing credit card payments through the merchant gateway module. The system won't add the token to WHMCS until someone has submitted a payment through the module. The system will store the credit card details in the database directly until the client makes a payment on an invoice through one of the token type gateway modules. After the payment is complete, the system fetches the token and replaces the credit card details in the database. Storage of the credit card details can also happen when the client updates their credit card details or when they place an order and the system does not process the payment immediately.

Payment gateway modules allow you to accept payments of many types directly within WHMCS.

You can access this feature at Configuration () > System Settings > Payment Gateways or, prior to WHMCS 8.0, Setup > Payments > Payment Gateways.

Activating a Payment Gateway

To activate a new payment gateway:

  1. Find the payment gateway:
    • In WHMCS 8.6 and later, go to Configuration () > Apps & Integrations.
    • In WHMCS 8.0 to 8.6, go to Configuration () > System Settings > Payment Gateways.
    • In WHMCS 7.10 and earlier, go to Setup > Payments > Payment Gateways.
  2. Click Activate.
  3. Configure the payment gateway (see below).

Setting Up Gateway Modules

Watch Video Tutorial

Each gateway has its own specific requirements in order to process transactions, which vary from gateway to gateway. However, all gateways have three core options:

  • Show on Order Form — Whether to display the payment gateway on the order form and client area, subject to product group gateway restrictions. Also controls adding new payment details via the Admin Area for merchant gateways.
  • Display Name — The gateway's name throughout the system and to clients (for example, an Authorize.net gateway could use the visible name Credit Card).
  • Convert To For Processing — When using multiple gateways, some gateways may not accept all the currencies you offer on your site. 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 and USD, you would need to select GBP for Convert To. This will use the rates in Configuration () > System Settings > Currencies or, prior to WHMCS 8.0, Setup > Payments > Currencies, to do the conversion. You can set this to auto-update daily.
    • For more information, see Converting Invoices to a New Currency.

Supported Gateway Modules

WHMCS includes the following payment gateways by default:

  • Merchant Gateways store credit card information securely in the WHMCS database.
  • Third-Party Gateways direct the client to the provider's website to process payments off-site.
  • Tokenisation Gateways reduce PCI liabilities when they perform repeat billing by storing the original transaction details or a reference number and not the full credit card number. For more information, see Working with Tokenization.

Remote Update Card

For tokenisation gateways with the Remote Update Card feature, clients can enter their card details via the WHMCS Client Area. This is done via an interface that the payment gateway hosts directly or by paying an invoice. This creates a profile in the payment gateway's system that returns a token.

WHMCS uses this to manage the card detail update requests via the Client Area and recurring payments. This does not store the full card details on your server, and some token gateways never touch it.

Email Templates

The type of payment gateway that you select influences which invoice notification email template it sends.

Third-party gateways will send the Invoice Created email template, while merchant and tokenisation gateways will send the Credit Card Invoice Created email template. This allows you to customise the payment instructions to clients for the different payment processes.

Attempt Capture

The type of payment gateway also influences the behaviour when you click Attempt Capture on the invoice page in the Admin Area.

  • For third-party gateways, the system will deactivate the button because the client needs to click the payment button on the invoice to send payment.
  • For merchant gateways and tokenisation gateways, the button will be active and staff can click Attempt Capture to instantly capture payment from the client's credit card.

Viewing Balances and Transactions

We added this feature in WHMCS 8.2.

You can view payment gateway balances for Stripe, PayPal Basic, PayPal Payments, and PayPal Card Payments at Billing > Transactions in the WHMCS Admin Area. This lets you check your financial details sooner and stay aware of trends and changes.

  • The displayed balances remain in the cache for a specific amount of time and will then automatically refresh. You can also manually refresh them.
  • When you click on a transaction in this list, additional information will display for that transaction.
  • Balances display by default for admins with the Full Administrator role. To make this information available to other admins, assign the View Gateway Balances permission to the desired role.
If you use Stripe, you can also view balances in the Admin Area Dashboard widget.
For information about displaying balances in custom development, see our Developer Documentation.

Custom Gateways

You can create your own gateway modules for WHMCS if you want to integrate with a gateway that WHMCS doesn't offer by default.

For more information, see our Developer Documentation.

Deactivating Gateway Modules

When you stop using a payment gateway, make certain to deactivate it. Deactivation prevents new payments using this gateway and will automatically reassign any products, services, invoices, transactions, and pay methods to the new payment gateway.

To deactivate a payment gateway, click Deactivate. The system will prompt you to select an alternative payment gateway.

Change any currently-assigned items to this gateway.

Migrating Payment Gateways

For instructions to stop using one payment gateway and switch to another, see Migrating Payment Gateways.

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: 

4007000000027 - Visa Test Card
4012888818888 - Visa Test Card II
4000000000000002 - Visa Test Card III
