Chargely SDK for PHP

The official Chargely SDK for PHP greatly simplifies technical implementation of Chargely features. The SDK is open source and hosted on GitHub.


  • Is built for PHP 5.4+ and is compliant with PSR-4 autoloaders.
  • Is easy to install through Composer.
  • Simple API. You don’t need to worry about certain implementation details. With SSO, for example, you don’t need to worry about certain JWT fields or which hashing algorithm to use; these are all handled for you.
  • Better support. We’ll be much better positioned to provide technical assistance for your implementation.
  • Better security & stability. We’re constantly updating the library with security updates and bug fixes.
