Add Payments to an Existing App
Example prompts
Generic requests: "Add payment to this app", "Add checkout".
Or alternatively, if the merchant is familiar with the SDK: "Add Simply Connect to this app.", "Add GooglePay flow", "Add the Fields module".
The builder works with the app you already have, adding a complete Nuvei checkout without disrupting your existing screens, branding, or functionality.
- The builder starts by asking a few questions about your app.
- If you didn't specify a module in the prompt, it will give you a list of all the available modules in the SDK (Simply Connect, Fields, Apple Pay / Google Pay) and explain each one.
- Collects a few details before it starts implementing:
- how to proceed with the backend (see Spin Up a Test Backend and Connect to an Existing Backend)
- which currency you will charge in
- which environment - integration (sandbox, for testing) or production
- a test buyer email. Nuvei rejects a payment with no buyer email, so the generated app carries one. You're always asked; you can keep the example.
- The builder adds the payment functionality to your code and asks whether it should match your app's existing design.
- Runs the app in an emulator.
