# Verify your domains for Apple Pay and Google Pay

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Card security and SCA](https://agentwranglers.se/playbook/payments/card-security-and-sca.md).

- ID: PAY-77
- Level: Recommended
- Chapter: [Card security and SCA](https://agentwranglers.se/playbook/payments/card-security-and-sca.md)
- Rule: Register every domain and subdomain that shows a wallet button with the provider. Serve Apple's domain association file there with status 200 and no redirect.
- Check: For each domain in the list, a request for `/.well-known/apple-developer-merchantid-domain-association` returns 200 with no redirect. The provider's dashboard or API lists the same domains as verified. A browser test on Safari staging shows the Apple Pay button.
- Applies when: The project takes payments.
- How: Apple Pay on the web shows its button only on domains registered for your merchant ID. Apple checks the file at `/.well-known/apple-developer-merchantid-domain-association` on each domain. Each subdomain counts on its own, so `shop.example.com` needs its own entry. Most providers register the domain through their dashboard or API and give you the file to serve. The wallet sheet is the provider's own payment page. So it keeps you on SAQ A, as [Choose a checkout that keeps you on SAQ A](https://agentwranglers.se/playbook/payments/card-security-and-sca/pci-saq-a-integration.md) says. Serve it over HTTPS with a valid certificate. Leave the file name without an extension, and never redirect it, since Apple's check then fails. Google Pay on the web needs the site approved for production in the Google Pay and Wallet Console, unless your provider registers it for you. Add a new domain to the list before launch, not after customers miss the button. Add the file path to the allow list of [standard addresses](https://agentwranglers.se/playbook/website/standard-addresses.md) if your server blocks unknown paths.

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### JavaScript example

```js
const WALLET_DOMAINS = ['example.com', 'shop.example.com']
const ASSOCIATION_PATH = '/.well-known/apple-developer-merchantid-domain-association'

for (const domain of WALLET_DOMAINS) {
  const response = await fetch(`https://${domain}${ASSOCIATION_PATH}`, { redirect: 'manual' })
  if (response.status !== 200) throw new Error(`${domain}: association file answered ${response.status}`)
}
```

### Python example

```python
import requests

WALLET_DOMAINS = ["example.com", "shop.example.com"]
ASSOCIATION_PATH = "/.well-known/apple-developer-merchantid-domain-association"

for domain in WALLET_DOMAINS:
    response = requests.get(f"https://{domain}{ASSOCIATION_PATH}", allow_redirects=False, timeout=10)
    assert response.status_code == 200, f"{domain}: association file answered {response.status_code}"
```
