_{Full disclosure: I work at Braintree. If you have any further questions, feel free to contact [support][support]}

The merchant ID is a required API credential for all Braintree API Calls, along with with the public and private key. You are able to see submerchants in your dashboard without the merchant ID because our system recognizes your login to the Dashboard as valid authentication instead of relying on the API Credentials.

When using our SDKs, you will need to set up your API Credentials appropriately. You can find the API Credentials for your account by following the instructions in our documentation. We now support both class level and instance methods.

Class Level Example

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('use_your_merchant_id');
Braintree_Configuration::publicKey('use_your_public_key');
Braintree_Configuration::privateKey('use_your_private_key');

Instance Method Example

$gateway = new Braintree_Gateway([
    'environment' => 'sandbox',
    'merchantId' => 'use_your_merchant_id',
    'publicKey' => 'use_your_public_key',
    'privateKey' => 'use_your_private_key'
]);
