Paddle Sample Checkout Module

Paddle Sample Checkout Module

Developed By Paddle

Compatible with WHMCS v7.7

Paddle Payment Gateway Module

The WHMCS service allows integrations with third party payment gateways via the use of custom modules. This module facilitates integrating Paddle ( with WHMCS via a custom module.

Current Workflow

Below is a description of the WHMCS purchase flow utilising this Paddle module:

  • At the moment, the WHMCS admin dashboard is used to add products/subscriptions
  • Once this is complete, customer are ready to visit the site, and are directed to the WHMCS basket to add their products
  • After products are selected and all demographic details are filled in in the WHMCS interface, there is a call to action to "Checkout"
  • Using this module, this call to action in WHMCS invokes the Paddle Custom Checkout API (
  • This creates a custom, tailored checkout process for the customer, passing in the amount's, email, country, postcode, etc. Paddle then collects the payment, and the Paddle interface can be configured to show the customer a success page on order completion, as well as send webhook alerts to WHMCS endpoints to reconcile invoices

In V1 of this module, the checkout is implemented, and post-purchase callback function is based on the WHMCS invoice ID. The module can facilitate either one time product purchases or recurring subscriptions, and Paddle is responsible for managing the recurring billing.

Paddle, as a Merchant of Record, then also handles receipt's, international sales tax, multiple payment methods, localised pricing and languages and buyer support amongst other things.

Usage and support

This code is provided as an example plugin to implement the Paddle checkout on a WHMCS instance. End users may use or modify the code as required as they see fit, as each WHMCS and Paddle implementation can be quite different.

This plugin is not provided by nor supported by Paddle, and Paddle does not provide technical support or maintenance for this plugin or any derivations of it.

This no longer works, at least fully.
Paddle states that all "pay links" need to be loaded via the js api, you cannot simple redirect the user to checkout after generating the pay link.
This means that you cannot use this module as it is. You can still use it to generate the pay link and accept the callback, but the generated pay link needs to be loaded via js using the "override" argument on "".

Great! module. Thank you so much.

Mr. Bhagwan Sahane @Logicmaker I have no idea without checking why you give one start ?! It's not good that you are promoting your own module by giving him one start. He is giving a working module for free but you are making huge money with yours. You should respect people's efforts.

He clearly mentions that this is not an official paddle module. but the owner is so helpful he helped me to set up on my site. <3 ^_^

Hello All,

Some one just added a sample gist on
which seems is not serious about providing solutions for their customers.

We @Logicmaker, already providing complete and working module for all latest versions of WHMCS.

For anyone that is interested, this module has been confirmed to work properly. It is provided "as is", so certainly could require edits to the PHP files depending on the WHMCS instance, or based on the billing model that is being used.

My attempt to provide a "free example" to help interested developers has unfortunately elicited reviews like this one, who will most likely provide a similar module to this one at a high price. For any PHP developers that are happy taking this module, reading the WHMCS and Paddle documentation and tweaking it to their own needs, this should be sufficient.
