## Guzzle Documentation Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services. - Simple interface for building query strings, POST requests, asynchronous requests using the same interface. - Uses PSR-7 interfaces for requests, responses, and streams. This allows you to utilize other PSR-7 compatible libraries with Guzzle. - Abstracts away the allowing you to write environment and transport agnostic code; i.e., no hard dependency on cURL, PHP streams, sockets, or non-blocking event loops. • Middleware system allows you to augment and compose
