Merchant API

Merchant API

Once you have an access_token, you are ready to perform actions on behalf of that merchant.

The only difference between the API to perform actions on behalf of a merchant and for a merchant performing their own actions is that the gateway object used to make API calls must be instantiated with an access token instead of a client ID and secret.

Creating a transactionAnchorIcon

This is how to create a transaction using an access token:
  1. Callback
  2. Promise
const gateway = new braintree.BraintreeGateway({
    accessToken: useAccessTokenForMerchant
});

gateway.transaction.sale({
    amount: "10.00",
    paymentMethodNonce: nonceFromTheClient,
}, (err, result) => {
    const transactionId = result.transaction.id;
});

Creating a customerAnchorIcon

Here's how you would create a customer for a merchant:
  1. Callback
  2. Promise
const gateway = new braintree.BraintreeGateway({
    accessToken: useAccessTokenForMerchant
});

gateway.customer.create({
    firstName: "Joe",
    lastName: "Brown",
    email: "joe@example.com",
    phone: "312-555-1234"
}, (err, response) => {
    const customerId = response.customer.id;
});

Authentication errorsAnchorIcon

The merchant has the right to revoke an authorization grant at any time. If this occurs, you will receive a exceptions.AuthenticationError when attempting to take any action on the merchant’s behalf.
