curl with OAuth2 Client Credentials

See more CURL Examples

This example shows how to run a simple CURL command with an OAuth2 access token for authorization. We use CURL to retrieve a SharePoint site ID, and Chilkat automatically fetches the OAuth2 access token using the provided credentials. Xbase++

//  This example will run the following curl command

//  curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \

//    -H "Accept: application/json"

//  The placeholders {{sharepoint_hostname}} and {{site_name}} represent variables that must be defined before execution.
//  When DoYourThing runs the curl command, it automatically substitutes these placeholders with their corresponding values.
