Fastlane

Server-side

Step 1: Generate client token

To get started, generate a client token. If you use Braintree's GraphQL API on your server, refer to the GraphQL Documentation.
Using Braintree SDK

Important

You must include your root domain in the client token request. Omitting the root domain will cause Fastlane to malfunction and will prevent it from working entirely.

node.js

import braintree from 'braintree';

let gateway;
let clientToken;

gateway = new braintree.BraintreeGateway({
    environment: braintree.Environment.Sandbox,
    merchantId: BRAINTREE_MERCHANT_ID,
    privateKey: BRAINTREE_PRIVATE_KEY,
    publicKey: BRAINTREE_PUBLIC_KEY,
});

gateway.clientToken.generate({
    domains: ['example.com','example2.com'],
}, (error, response) => {
    if (error) {
        // handle the error
        return;
    }
    // pass the clientToken to your front-end
    clientToken = response.clientToken;
});

Using Braintree GraphQL

Graphql

mutation ($input: CreateClientTokenInput) {
    createClientToken(input: $input) {
        clientToken
    }
}

Graphql

{
    "input": {
        "clientToken": {
            "domains": [
                "example.com"
            ]
        }
    }
}

Restrictions on Domain Names:
- No Subdomains: Do not specify subdomains (for example, "sub.example.com").
- No Wildcards: Do not use wildcard characters (for example, "*.example.com").
- No Protocols: Do not include HTTP or HTTPS protocols in the domain name (for example, "https://example.com/")
Error Handling: If you specify subdomains, wildcards, or protocols, the system will generate an error.

Step 2: Update Fastlane with Consumer's shipping address

After generating a Fastlane token, if you're processing a payment, make sure to include the customer's shipping address in the request.This ensures the address is saved to their Fastlane profile for future use.

Field name	Description	Link
shipping	The shipping address collected for a customer's order.	Link

node.js

gateway.transaction.sale({
    amount: "10.00",
    paymentMethodNonce: nonceFromTheClient,
    deviceData: deviceDataFromTheClient,
    customer: {
        firstName: "Drew",
        lastName: "Smith",
        email: "drew@example.com",
    },
    billing: {
        firstName: "Paul",
        lastName: "Smith",
        company: "Braintree",
        streetAddress: "1 E Main St",
        extendedAddress: "Suite 403",
        locality: "Chicago",
        region: "IL", //must be sent in 2-letter format
        postalCode: "60622", // you can also use the countryCodeAlpha3 or countryCodeNumeric formats
        countryCodeAlpha2: "US",
    },
    shipping: {
        firstName: "Jen",
        lastName: "Smith",
        company: "Braintree",
        streetAddress: "1 E 1st St",
        extendedAddress: "5th Floor",
        locality: "Bartlett",
        region: "IL", //must be sent in 2-letter format
        postalCode: "60103", // you can also use the countryCodeAlpha3 or countryCodeNumeric formats
        countryCodeAlpha2: "US",
        phoneNumber: "14155551212",
        shippingMethod: "ground",
    },
}, (error, result) => {
    if (error) {
        console.error(error);
        return;
    }

    if (result.success) {
        console.log("Transaction ID: " + result.transaction.id);
    } else {
        console.error(result.message);
    }
});

Using Braintree GraphQL

Graphql

mutation ($input: ChargeCreditCardInput!) {
  chargeCreditCard(input: $input) {
    transaction {
      id
      legacyId
      createdAt
      amount {
        value
        currencyCode
      }
      status
    }
  }
}

Graphql

{
  input: {
    paymentMethodId: paymentToken.id,
    transaction: {
      amount: '1.00',
      riskData: { deviceData },
      shipping: {
        shippingAddress,
        shippingMethod: 'GROUND',
      },
      customerDetails: { email },
      vaultPaymentMethodAfterTransacting: {
        when: 'ON_SUCCESSFUL_TRANSACTION',
      },
    },
    options: {
      billingAddress: paymentToken.paymentSource.card.billingAddress,
    },
  },
