Hello,

There is no error while consuming API

My issue is how to fetch the access token.

you need to create a server action for access token by consuming api for access token  and then pass into the api. this will revert your thing which you want. 

i am trying to tell you in this way. 

While testing, I Passed the client ID, client secret, and Other Parameters , In response, i didn't Get access token, I already tried with Server action, but Still Its not Showing   

Can you please Show this in Service Studio REST API 

i see. then try to check your client id and other parameter if its working on post man then it should work for it definitely. just check once.

Response is 200 ok 

oh. please try to read this blog.

https://success.outsystems.com/documentation/11/developing_an_application/secure_the_application/end_users/end_users_authentication/configure_azure_ad_authentication/

 i guess this will help you or PM me the client id and secret id so that i will try at my systems. or try to attach OML

I just want to fetch the user list from Azure AD to our OutSystems application. For that as well, we have to use this????

You don't have to do anything but that forge component offers an action called "GetApplicationToken". We use this action for the almost the same exact purpose, to call the Microsoft Graph to get a group user member list .

Used API: https://graph.microsoft.com/v1.0/groups?$filter={Filter}
