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. Visual FoxPro

* This example will run the following curl command

* curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \
*   -H "Authorization: Bearer ACCESS_TOKEN" \
*   -H "Accept: application/json"

loSb = CreateObject('Chilkat.StringBuilder')
loSb.AppendLn('curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \')
loSb.AppendLn('  -H "Authorization: Bearer ACCESS_TOKEN" \')
loSb.AppendLn('  -H "Accept: application/json"')

* Build the JSON that provides information for getting the OAuth2 access token using the OAuth2 client credentials flow.
loJsonOAuth2 = CreateObject('Chilkat.JsonObject')

loJsonOAuth2.UpdateString("oauth2.client_id","CLIENT_ID")
loJsonOAuth2.UpdateString("oauth2.client_secret","CLIENT_SECRET")
loJsonOAuth2.UpdateString("oauth2.scope","https://graph.microsoft.com/.default")
loJsonOAuth2.UpdateString("oauth2.token_endpoint","https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token")

loHttpCurl = CreateObject('Chilkat.HttpCurl')

* Provide the information for getting the OAuth2 access token from the token endpoint
* Note: The Authorization header specified in the curl command will be ignored and replaced using the OAuth2 access token obtained at runtime from the token endpoint.
loHttpCurl.SetAuth(loJsonOAuth2)

* 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.
* Below are the values assigned to these variables:
loHttpCurl.SetVar("sharepoint_hostname","example.sharepoint.com")
loHttpCurl.SetVar("site_name","test")

* Run the curl command.
