Before you integrate either the Native SDK or the Payment API Switch, you need to create a SumUp account in the SumUp Dashboard. Alternatively, you can request a test account by contacting firstname.lastname@example.org.
Once you have an account, you need to get an affiliate key by opening the Developers page for your registered account in the SumUp Dashboard and registering an Application Identifier that is equivalent to your package name or bundle ID in the format
Once you have set the affiliate key and Application ID, you have to add these to your app.
The affiliate key and Application ID coming from your app must match those obtained in the Developers page.
You are now ready to start integrating the SumUp payment capabilities in your app, provided you have also received a SumUp card terminal: Air, Air Lite, PIN+ terminal, Chip & Signature reader, or SumUp Air Register.
