System requirements

The server must fulfil the following requirements to run the SDK:

  • PHP 7.1 || 7.2 || 7.3 || 7.4 || 8.0
  • ext-json
  • ext-curl –> Can be replaced when implementing custom http-Adapter (ref. Custom HTTP adapter).

In addition the server must be reachable from the internet for the webhook events to work. If you are using basic auth protection make sure to whitelist the IPs of our webhook servers.
