# PayPal

## Developing / testing sandbox

### Buyer account

This is the account you'll use to make the (fake) payment. Go to [https://developer.paypal.com/developer/accounts/create](https://developer.paypal.com/developer/accounts/create), login with your personnal PayPal account then create a test account.

### Merchant account

1. Create an app here: [https://developer.paypal.com/developer/applications/create](https://developer.paypal.com/developer/applications/create)
2. Use the generated merchant credentials to set the following variables in API's `.env`:

```
PAYPAL_ENVIRONMENT=sandbox
PAYPAL_APP_ID=APP-________
PAYPAL_CLIENT_ID=________________________
PAYPAL_CLIENT_SECRET=________________________
```

1. Create buyer's credentials on [https://developer.paypal.com/developer/accounts/create](https://developer.paypal.com/developer/accounts/create)

And you're ready to go. Use the credentials generated in step 3. to authenticate when ordering.

## Known issues

* The button may require multiple clicks to trigger on dev or staging. It should not affect production (see [https://github.com/paypal/paypal-checkout/issues/471](https://github.com/paypal/paypal-checkout/issues/471))
