Braintree for Cordova

This is a Cordova plugin for the Braintree mobile payment processing SDK. It extends the Cordova Purchase Plugin to add Braintree support using the Braintree DropIn interface.

This plugin requires at least cordova-plugin-purchase version 13.

Installing

The plugin identifier is cordova-plugin-purchase-braintree. Here's how to adding it to your app with the cordova CLI:

cordova plugin add cordova-plugin-purchase-braintree

For Android, you have to make sure the minSdkVersion is at least 21 in your app's config.xml file. To do so, add (or update) the preference tag for the android platform as below:

<platform name="android">
    <preference name="android-minSdkVersion" value="21" />
</platform>

For iOS, the minimum deployment target for the Braintree SDK is iOS 12.0, to set this up, add (or update) the preference tag for the ios platform like so:

<platform name="ios">
    <preference name="deployment-target" value="12.0" />
</platform>

Usage

Initialization

When initializing the purchase plugin, add Platform.BRAINTREE at initialization.

CdvPurchase.store.initialize([{
    platform: CdvPurchase.Platform.BRAINTREE,
    options: { ... }
}]);

The options object should contain:

• a clientTokenProvider or a tokenizationKey string.
• optional configuration options for Apple Pay, Google Pay and 3DSecure.

Client Token or Tokenization Key

Check the Braintree documentation to understand the difference.

clientTokenProvider is a function that takes a callback as a parameter, this callback will accept either:

• a string: the Client Token
• a CdvPurchase.IError object ({isError: true, code: ErrorNumber, message: string}).

The CdvPurchase.Iaptic object contains the implementation of a client token provider. So you if you are using https://www.iaptic.com, you can do:

const iaptic = new CdvPurchase.Iaptic({
  url: 'https://validator.iaptic.com', appName: 'MY_APP_NAME', apiKey: 'MY_PUBLIC_KEY',
});

store.initialize([Platform.APPLE_APPSTORE, Platform.GOOGLE_PLAY, {
    platform: Platform.BRAINTREE,
    options: {
        // using iaptic's built-in braintree client token provider
        clientTokenProvider: iaptic.braintreeClientTokenProvider
    }
}]);

tokenizationKey is just a string.

Making a purchase

Use the store.requestPayment() method to initiate a payment with Braintree.

• amountMicros and currency are required.
• If result.isError is set, the returned value is an error.
  • Check result.code, PAYMENT_CANCELLED means the user closed the modal window.
  • Other error codes means something went wrong.

store.requestPayment({
  platform: CdvPurchase.Platform.BRAINTREE,
  email: GetEmailAddress(),
  items: [{
    id: 'item_id',
    title: 'An Item',
    pricing: { // 11 USD
        priceMicros: 11 * 1000000,
        currency: 'USD',
    }
  }],
  description: 'An item delivered before Christmas',
})
.cancelled(() => {
  // request cancelled by user
})
.failed(error => {
  // request failed
})
.initiated(transaction => {
  // transaction initiated
})
.approved(transaction => {
  // transaction initiated
})
.finished(transaction => {
  // transaction finished
});

Once the client gets the initial approval, the "approved" event is triggered. It's the job of the receipt validation service to create and submit a transaction to Braintree.

Once again, iaptic has built-in support for Braintree, so this part is already covered if your app is integrated with Iaptic. If now, implement the server side call using values provided by the receipt validation call.

3DSecure

To enable 3DSecure, you have to add threeDSecure into the platform options.

Example:

{
  platform: Platform.BRAINTREE,
  options: {
    // ...
    threeDSecure: {
      exemptionRequested: true
    }
  }
}

It can also be an empty object if you don't have any specific options to set. The list of accepted options is documented here: ThreeDSecure.Request.

Those options will be merged into all Braintree payment requests. They can be overloaded by adding threeDSecureRequest in the payment request' additional data, for example:

CdvPurchase.store.requestPayment({
    platform: CdvPurchase.Platform.BRAINTREE,
    items: [/* */],
    email: GetEmailAddress(),
}, {
  braintree: {
    threeDSecureRequest: {
      exemptionRequested: false
    }
  }
});

threeDSecureRequest is of the same type: a ThreeDSecure.Request object.

Google Pay

To enable Google Pay, you have to add googlePay into the platform options.

Example:

{
  platform: Platform.BRAINTREE,
  options: {
    // ...
    googlePay: {
      countryCode: 'US',
      googleMerchantName: 'My Merchant Name',
      environment: 'TEST'
    },
  }
}

The list of accepted options is documented here: GooglePay.Request.

Those options will be merged into all Braintree payment requests. As with 3DSecure, those options can be overloaded by adding googlePayRequest into the payment request's additional data, for example.

CdvPurchase.store.requestPayment({
    platform: CdvPurchase.Platform.BRAINTREE,
    items: [/* */],
}, {
  braintree: {
    googlePayRequest: {
      shippingAddressRequired: true,
    },
  }
});

Apple Pay

The cordova-plugin-purchase-braintree-applepay plugin is an extension that enables support for Apple. By installing this plugin, you can add support for Apple Pay to your Cordova app, through Braintree.

Documentation related to Apple Pay can be found in that repository.
