Expo Config Plugin

The @gmisoftware/react-native-pay Expo config plugin configures native projects so Apple Pay and Google Pay work without manual edits.

Usage​

Add the plugin to app.json or app.config.js:

{
  "expo": {
    "plugins": [
      [
        "@gmisoftware/react-native-pay",
        {
          "merchantIdentifier": "merchant.com.yourcompany.app",
          "enableGooglePay": true
        }
      ]
    ]
  }
}

Options​

Both options are optional. Listed without options ("plugins": ["@gmisoftware/react-native-pay"]), the plugin changes nothing.

OptionTypeDescription
merchantIdentifierstring or string[]Apple Pay Merchant ID(s). If omitted, Apple Pay entitlements are not added. Each ID should start with merchant.; prebuild warns when one does not.
enableGooglePaybooleantrue adds the Google Pay metadata (com.google.android.gms.wallet.api.enabled) to the Android manifest. false removes it. If omitted, the manifest is left as it is, so an entry added by another plugin (Stripe, for example) stays.

Examples​

iOS only (Apple Pay):

["@gmisoftware/react-native-pay", { "merchantIdentifier": "merchant.com.example.app" }]

Android only (Google Pay):

["@gmisoftware/react-native-pay", { "enableGooglePay": true }]

Both platforms:

["@gmisoftware/react-native-pay", {
  "merchantIdentifier": "merchant.com.example.app",
  "enableGooglePay": true
}]

Multiple Merchant IDs (iOS):

["@gmisoftware/react-native-pay", {
  "merchantIdentifier": ["merchant.com.example.app", "merchant.com.example.other"],
  "enableGooglePay": true
}]

After changing the plugin​

Run:

npx expo prebuild --clean

Then rebuild and run the app.
