coinbase php api

I have developed a site which will make micro payments to users in bitcoins, to reward them for their activity. I have a Coinbase account, and want to use Coinbase's API to start paying users with Bitcoins. > Has to be PHP > Has to use Coinbase > Has to use the Coinbase API I have installed DRUSH and Composer on my shared Linux server (Godaddy) but I am unable to access with the API. The PHP I have tried is as follows: <? use Coinbase\Wallet\Client; use Coinbase\Wallet\Configuration; $configuration = Configuration::apiKey($apiKey, $apiSecret); $client = Client::create($configuration); ?> It is possible I have installed Composer or DRUSH incorrectly on the server. I just need somebody who has done this before to look at the [login to view URL] file and the php file and tell me why is not working. Happy to pay $100 USD for this if you can provide me with the answer. This is a very simple problem so needs to only take 1 or 2 hrs at the most. I only want to hear from people who have worked with the Coinbase API (PHP) before. Tks for reading
