OpenCart is an open source platform for online shops. You can choose from a huge eCommerce selection of 13000+ modules and themes to expand the functionality of your shop. One of those plugins is the wallee OpenCart Plugin. Accept payments seamlessly in your OpenCart store with the wallee payment plugin without redirection. This plugin is compatible with all the available OpenCart 2.x versions. The plugin can be retrieved via the GitHub or in the OpenCart market place.

wallee connects your Plentymarkets store and accepts payments securely.

Setup and Scale

The setup of the plugin is quite easy. You get the plugin directly from the github repository. Once the plugin is installed you can start to accept payments. The best thing is you can easily add additional payment processors or payment methods with just one click due to the standardized payment flow. You do not even have to update the plugin due to its automatic synchronization. Additionally, the checkout flow is seamlessly integrated in your store with no redirection to the payment page.

Invoices, printing and ISR

You can make use of a huge variety of features like e.g. create your customizable invoices and send them directly to your customers. You can print them for example through cloud printing where the documents and invoices will be printed directly on your local printer. In addition to that, you can make use of local payment schemes like Sofort, Swish, Alipay, Credit Cart, ISR payments in Switzerland, where we generate the ISR payment slip and take care of all further processing steps like the dunning of open invoices or automatic reconciliation of payment records including their synchronization back to OpenCart.

Seamless integrated solution

The look and feel offers a fully seamless integrated solution without redirection to the payment page of the processor. You can integrate the payment form directly in the store and it still stay fully PCI compliant. The integrated payment page uses an adjustable iframe that gives your clients the feeling that it is seamlessly integrated - even on mobile devices. Convince yourself by looking at the demo integration you find below.


The setup is easy and can be done in a few steps within some minutes:

  1. Simply upload the plugin and install the plugin in your shop. The plugin will automatically create the needed webhooks and create the payment methods.
  2. After creating a wallee account and set up a space, you need to create an application user that is allowed to access the space you want to link to the OpenCart store. Navigate to your account > application user and create your application user. The user ID and the authentication key will be shown to you.
  3. Setup at least one processor, one payment method and a connector configuration. More Information about the processor concept can be found in the documentation.
  4. Configure the plugin directly in the backend of your OpenCart shop. Once you entered the Space ID and user credentials the plugin will perform the configuration automatically.
  5. Then you need to activate the payment methods you’ve activated in your space.
  6. For the transaction processing you’ll be forwarded to the payment page of wallee. You can design this page with the help of TWIG templates. More information about that can be found in the documentation.
