I want to call arcgis web api to get the list of all users and groups in my organization, using a token I have generated during authentication process.
I have tried a couple of options but none of them seems to work:
I don't know if there is something wrong with URL or with parameters. I have been trying for more then 2 week to solve this but nothing seems to work.
I have analysed the Rest API reference ArcGIS REST API but still couldn't find the solution.
