Can I get a test profile?

To get started with SumUp first login (if you don't have a SumUp profile you will first need to register). To activate your SumUp Profile follow the Activate my profile steps.

Once you have an active SumUp Profile, go to https://developer.sumup.com/, navigate to the Test profile setup page by clicking on "Create test account" on the right side of the navigation, and then create your profile by click on the "Setup test profile" button. Your Test profile will be created for the same country as your merchant.

Once your profile is generated copy and store safely the user name (format: 32 [email protected]) and randomly generated unique password.

Note: You will not be able to access your password afterwards make sure to store it safely before dismissing the message

Can I integrate SumUp to my website?

Yes, as a SumUp merchant you have the option to integrate SumUp’s eCommerce service with a webshop plugin or via direct integration.

SumUp’s official plugin supports integrations with WordPress/WooCommerce.

For PrestaShop users we recommend this plugin developed by a SumUp partner.

For WIX users we recommend following their native solution.

The direct integration option uses the SumUp eCommerce Checkout API, intended for developer utilisation. All information can be found in our Online Payments section. Before following our guides, make sure to request a test profile.

How do I set up OAuth credentials?

You can create credentials by logging in on the SumUp Developer page and navigating to the "Create Client Credentials" section. Detailed information on how to authenticate further can be found in our step-by-step guide or in this video.

What is a test profile?

SumUp test profiles mirror regular profiles, including sharing the same rules as them. However, test profiles don’t have a connection to service providers, nor do they process transactions with real funds.
