First, you'll want to select your preferred integration method, decide on the payment methods you want to support, and pick any other APIs or capabilities you think you'll find useful.

By default, you can test all your card payment flows. However, if you require any alternative payment methods (e.g., PayPal, Sofort, iDEAL) you can contact our Integration team at to enable them on your test account.

Once you've run some initial tests to make sure everything's running smoothly, you can then apply for a live account to start processing payments with us. Please contact our Sales team at We'll need you to complete an online application form, which will then be reviewed by our in-house Onboarding team.

We may ask you to provide further documentation, including corporate structure documentation, legal entity details, bank account information, and principal owners.

Once approved, you’ll execute a contract and we'll provide you with your production credentials.

We then recommend that you perform a test transaction, or run a pilot in production, before processing real customer transactions. This gives you the opportunity to ensure that everything is set up correctly and will work as expected.

After that, you're ready to start accepting live payments from your customers!

Find out more about the events for which you can create webhooks.

Payments and refunds

You can find the Acquirer Reference Number (ARN) for a payment in the Payments section of the Hub. Just click on the relevant payment action to open up the summary, and you'll find the ARN under the Action details heading.

Alternatively, you can find the ARN in the response of the get payment actions endpoint, as well as in the payment_captured and payment_refunded webhook notifications.

Typically, this means that the customer's card issuing bank (or the acquirer) has declined the transaction. For example, if the CVV is incorrect or the card cannot be used for online transactions. The cardholder should contact their issuing bank to understand what has happened.

You can find out about the other response codes here.

  • Store the expiry date in your database, then carry out a date verification before processing the charge.
