Custom Integration Overview

Integrate the SDK

• Install the SDK in your application.
• Perform the first transaction from your own app.

Implement mandatory features

The following features are required in your app:

• Integrate a signature screen.
• If your app will be used by multiple merchants: load merchant data from your backend to route payments correctly.
• Let the merchant send ready-made receipts.
• Let the merchant abort the transaction.

Optional: Extra Features & Backend Integration

The following features are optional:

• Enable the merchant to refund transactions.
• Create custom receipts for your merchant.

Via our API, you can access and control payments directly from the backend:

• Your backend can be notified about transaction events with WebHooks, you can register and query transactions and issue refunds and receipts.

• If you haven't done so, use the Developer Kit to check how using a real card reader with your app looks like.
• Go through a set of test cases and submit your receipts and a video of a transaction for us to review.

With a green light from your account manager, start processing live transactions:

• Do the last steps before going live.
