Integrate Cost+ with your modified eCommerce shop using the MMLC module

modified eCommerce

Integrate Cost+ as a payment method in your modified eCommerce shop. The NoPayn Payment Gateway module is installed via the Modified Module Loader Client (MMLC) and supports Credit/Debit Cards, Apple Pay, Google Pay, and Vipps/MobilePay.

Prerequisites

  • Active Cost+ merchant account
  • modified eCommerce shop with admin access
  • MMLC installed on your shop

1. Install MMLC (if not already installed)

Download MMLC from module-loader.de. Upload the ModifiedModuleLoaderClient folder to your shop root directory.

Once uploaded, access MMLC at:

https://your-shop.com/ModifiedModuleLoaderClient/

2. Add the NoPayn Module Repository

In MMLC, click the Settings icon (gear icon). Under Module repositories, add the following repository URL:

https://github.com/NoPayn/modified-nopayn.git

Click Save to confirm.

3. Install the Module

In MMLC, search for "NoPayn" or browse the Payment category. Click Install on "NoPayn Payment Gateway", then click Link to deploy the module files into your shop.

The Link step copies the module files into the correct shop directories. Make sure your file permissions allow MMLC to write to the shop folder.

4. Activate Payment Methods

Navigate to Admin → Modules → Payment in your shop admin panel. You'll see the available Cost+ payment methods:

  • Credit / Debit Card
  • Apple Pay
  • Google Pay
  • Vipps/MobilePay

For each method you want to offer:

  1. Click Install
  2. Enter your NoPayn API key (from your NoPayn dashboard → Settings → API Key)
  3. Set the Completed Order Status (e.g. "Processing" or a custom status)
  4. Click Save

You can find your API key in the Merchant Portal under Websites → your website → Integration.

5. Test and Launch

Place a test order in your storefront to verify the integration:

  1. Add a product to the cart and proceed to checkout
  2. Select one of the Cost+ payment methods
  3. You'll be redirected to the NoPayn payment page
  4. After payment, the order status should update automatically in your shop admin

Make sure to test with your test API key before going live. Switch to your production key only after verifying the full payment flow.
