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. C#
BraintreeGateway gateway = new BraintreeGateway(useAccessTokenForMerchant);
var request = new TransactionRequest {
    Amount = 100.00M,
    PaymentMethodNonce = nonceFromTheClient
};
Result<transaction> result = gateway.Transaction.Sale(request);
string transactionId = result.Target.Id;

Creating a customerAnchorIcon

Here's how you would create a customer for a merchant:
  1. C#
BraintreeGateway gateway = new BraintreeGateway(useAccessTokenForMerchant);
var createRequest = new CustomerRequest() {
    FirstName = "Joe",
    LastName = "Brown",
    Email = "joe@example.com",
    Phone = "312.555.1111"
};
Result<customer> result = gateway.Customer.Create(createRequest);
string customerId = result.Target.Id;

Authentication errorsAnchorIcon

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