## Requirements

<AccordionGroup>
  <Accordion title="HTTPS required" icon="lock">
    Wallet payments do not work on insecure HTTP origins. Serve all checkout pages over `https://`.
  </Accordion>

The file is the same for every merchant. See [Apple Pay domain verification](/rinne-js/wallet-elements#apple-pay-domain-verification) for details.
  </Accordion>

  <Accordion title="Content Security Policy" icon="shield">
    If your application uses CSP headers, allow these origins:

    script-src https://js.evervault.com;
    connect-src https://keys.evervault.com https://api.evervault.com https://api.rinne.com.br https://api-sandbox.rinne.com.br;
    frame-src https://ui-components.evervault.com;
    ```
  </Accordion>

  <Accordion title="User requirements" icon="user">
    For a successful checkout, users need:

    * A supported browser and device
    * A configured wallet with at least one eligible card
  </Accordion>
</AccordionGroup>

<Warning>
  Keep API keys server-side and process encrypted payloads from frontend elements on your backend.
</Warning>

## Browser support

| Browser                        | Apple Pay | Google Pay |
| ------------------------------ | --------- | ---------- |
| Safari (iOS 10+, macOS 10.12+) | ✅         | ✅          |
| Chrome                         | ✅         | ✅          |
| Firefox                        | ❌         | ✅          |
| Edge                           | ✅         | ✅          |
