Configure HTTP Transport

the php sdk does not specify a dependency on any http client to ensure better integration with existing systems and frameworks instead, the php http discovery package is used to allow us to detect a compatible http client where required if your application does not already use a psr 18 compatible client, you will need to install one before sending data to klevu's apis we recommend using guzzle , which can be installed with the following command bash composer install guzzlehttp/guzzle all services which interact with klevu's apis accept a http client instance via their constructor note if you are integrating into a modern framework, you should implement this via your dependency injection system even if automatic discovery succeeds to ensure better stability and application performance
