SamCart Checkout Bridge
SamCart Integration Module for WHMCS
SamCart Integration Module for WHMCS combines SamCart’s high-converting checkout experience with WHMCS billing, invoice tracking, and service management.
The module lets you map WHMCS products to SamCart checkout URLs, redirect customers from WHMCS invoices to the correct SamCart checkout, verify completed orders through the SamCart API, and record successful payments back inside WHMCS.
Use SamCart Checkout With WHMCS Automation
SamCart is built for conversion-focused checkout pages, while WHMCS is built for billing and service automation. This module connects both systems so you can use SamCart for the front-end payment experience and WHMCS for invoice and service management.
Core Features
- SamCart API Integration: Connect WHMCS using your SamCart API key.
- Product Checkout URL Mapping: Assign a SamCart checkout URL to each WHMCS product.
- Invoice-Based Redirection: Send customers from a WHMCS invoice to the correct SamCart checkout with the invoice ID attached.
- Order Verification: Fetch the SamCart order by order ID to confirm the payment status before updating WHMCS.
- Charged Status Processing: Applies WHMCS payment only when the SamCart cart item status is charged.
- Automatic Invoice Payment: Records the SamCart order ID and payment amount on the matching WHMCS invoice.
- Copyable SamCart Scripts: Provides scripts for SamCart product pages and post-purchase order completion handling.
- One Product Cart Flow: Includes a cart hook to keep the WHMCS checkout focused on one product at a time.
Product Mapping System
The included addon module creates a simple admin interface where you can view WHMCS products and save the related SamCart checkout URL for each one.
When a customer pays a WHMCS invoice, the gateway finds the invoice product, loads the saved SamCart checkout URL, and redirects the customer to the correct SamCart checkout page.

- WHMCS generates an invoice with SamCart as the payment method.
