Included in our Plus plan, access to our Payments API allows you to accept instant bank payments from your online checkout. Wonderful can sit alongside other payment methods (such as debit and credit cards, BNPL services or Paypal), but you'll need experience of working with APIs to complete the installation. Documentation is provided.

1. The first step is to check your business bank is supported  This is required to receive payments. Customer transactions are settled in real time, so the money is in your business account the moment your customer approves the payment.
2. Once you've confirmed we have integrated your bank, it's time to get you on board. To do this, sign up with Wonderful and set up your account.
3. From your One dashboard, select "Integrations" then "API" from the navigation menu on the left.

Installation of the API and a current subscription to our Plus plan is all that is required, which includes 2,000 monthly transactions for just £19.99 (plus VAT). There are no percentage charges and any transactions outside the inclusive bundle are charged at just 1p / transaction.

One API documentation

Our One API is based on restful JSON endpoints, and you can find the documentation at https://api.wonderful.one/

The API will allow you to do all the things you can do from the dashboard or the mobile app, including creating QR codes, quick payment links, and invoices.

If you have a specific requirement for using our API that you would like to discuss further, please email your requirements to [email protected] and we can set up a complimentary call with one of API developers or product managers.
