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.

php

$gateway = new Braintree\Gateway([
  "environment" => "sandbox",
  "merchantId" => Env::get("BRAINTREE_MERCHANT_ID"),
  "publicKey" => Env::get("BRAINTREE_PUBLIC_KEY"),
  "privateKey" => Env::get("BRAINTREE_PRIVATE_KEY",
)]);

// domain is required for Fastlane to work
$clientToken = $gateway->clientToken()->generate([
        'domain' => ['example.com','example2.com']
]);

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

php

<?php

function getGateway() {
  return new Braintree\Gateway([
    "environment" => "sandbox",
    "merchantId" => Env::get("BRAINTREE_MERCHANT_ID"),
    "publicKey" => Env::get("BRAINTREE_PUBLIC_KEY"),
    "privateKey" => Env::get("BRAINTREE_PRIVATE_KEY",
  ]);
}

function createTransaction(Request $request) {
  $data = $request->toArray();
  $gateway = getGateway();

  $result = $gateway->transaction()->sale([
    "amount" => "10.00",
    "paymentMethodNonce" => $data["paymentToken"]["id"],
    "deviceData" => $data["deviceData"],
    "options" => [
      "submitForSettlement" => true,
    ],
  ]);

  return new JsonResponse(["result" => $result]);
}

Using Braintree GraphQL

Graphql

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

Graphql

[
    "input" => [
        "paymentMethodId" => $data["paymentToken"]["id"] ?? null,
        "transaction" => [
            "amount" => "1.00",
            "riskData" => [
                "deviceData" => $data["deviceData"],
            ],
            "shipping" => [
                "shippingAddress" => $data["shippingAddress"] ?? null,
                "shippingMethod" => "GROUND",
            ],
            "customerDetails" => [
                "email" => $data["email"],
            ],
            "vaultPaymentMethodAfterTransacting" => [
                "when" => "ON_SUCCESSFUL_TRANSACTION",
            ],
        ],
        "options" => [
            "billingAddress" =>
                $data["paymentToken"]["paymentSource"]["card"][
                    "billingAddress"
                ] ?? [],
        ],
    ],
]
