Accept payments with WooCommerce

If you already have a WordPress website and would like to complete it with accepting payments, you can do so with the SumUp Payment Gateway for WooCommerce plugin. It will allow you to take payments in your online store with an easy and quick integration without any coding required.

The plugin is a lightweight integration option enabling your customizations and providing your customers the convenience of securely buying products from your website without being redirected to other pages. It accepts all major card schemes like VISA, MasterCard, American Express, Diners, Discover and JCB.

Transactions are processed through the SumUp payment platform allowing you to track your transaction history through the SumUp Dashboard.

If you're just getting started with SumUp review our allowed businesses list prior to signing up.

Requirements

To get started you will need an active SumUp account. As an authorized Payment Institution by the Central Bank of Ireland, SumUp will require certain documents to verify you as the individual and owner of the business you're registering with. Please make sure your business model is supported by SumUp, according to our allowed businesses article.

Installing the plugin

Automatic Installation

The automatic installation is the easiest option, as WordPress handles the file transfer and you don't need to leave your web browser.

1. Install the plugin via the Plugins section in the WordPress Dashboard
2. Click on Add new and search for SumUp Payment Gateway for WooCommerce
3. Then click on the Install Now button
4. Click Activate to active the plugin

Manual Installation

The manual installation method involves downloading our plugin and uploading it to your web server via your favorite FTP application. The WordPress codex contains instructions on how to do this.

Before setting up the plugin you must create your client credentials. They will be used afterwards to configure the plugins setup.

Integration Options

For plugin versions above 2.5 both a simple and advanced integration flow are available. If you are using a plugin version below 2.5, follow the steps in our advanced integration guide.
