Accept payments with WIX

This guide will help you set up SumUp as your payment provider on your WIX online store. By connecting your WIX dashboard to SumUp, you can accept payments through our secure and easy-to-use payment gateway.


Before you start, make sure you have:

  1. An active SumUp account. If you don't have one yet, you can sign up on our website. As an authorized Payment Institution by the Central Bank of Ireland, SumUp will require certain documents to verify your identity and business ownership. Please make sure your business model is supported by SumUp, according to our allowed businesses article.
  2. A WIX online store.

With this integration, the following Alternative Payment Methods (APMs) are available at checkout: iDeal (Netherlands), Bancontact (Belgium), P24 (Poland), EPS (Austria). Please note, that currently Apple Pay and Google Pay are not available.


Here's how you can connect SumUp to your WIX online store:

First, create your secret API Key:

  1. Access the Developer Portal.
  2. Click on "Login" on the top right corner of the screen.
  3. A new "Account" entry will show in place of "Login", hover over it and select "API Keys".
  4. Name your API key (e.g. "Wix") and click on "Create".
  5. Copy the Secret Key displayed in the pop-up window and save it on your computer. Make sure not to share this key with anyone.

Now, head over to your Wix dashboard and:

  1. Go to "Settings" and click on "Accept payments"
  2. Select "SumUp", paste your Secret API Key in the required field under "Account Information" and click on "Save"

That's it! You can now start accepting payments through SumUp on your WIX online store.
