Requests sent by monitors can be customized. Monitors use the GET HTTP method by default. To change it, go to Monitors → Select a monitor → Configure → Advanced settings → Request parameters. Here you can pick other methods like POST, PATCH and others.
You can also include specific parameters to be included in the request body.
There are two main authentication methods that can be used. The first one uses a header name and header value (for bearer token authentication). The second one is basic HTTP authentication with username and password.
This option is available in API Monitor and HTTP Status Code Monitor.
It takes less than a minutes to setup your first monitoring.
