You can use this SDK provided by BitPay to make requests to their api: Bitpay SDK. There you will find a very good documented guide that explains step by step how to install and use the SDK.
I will leave here the steps only to install the SDK.
BitPay SDK Installation
Install composer.
curl -sS https://getcomposer.org/installer | php
Install BitPay SDK using composer.
php composer.phar require bitpay/sdk:~3.0
Alternatively, you can install the SDK via composer by hand. Add the following to your composer.json file:
php composer.phar update bitpay/sdk
Final Note After following these steps you will be able to generate a key required to make requests. More information here.
