I have created SharePoint Designer Workflow. In that, I want to create workflow Task and assign the task to different users. I have One top level site that contains the Users list. I have to get all the users from the Top level site and create a task and assign that task to that particular user.

So for this, I have tried to get the users data from the Call HTTP service of the SharePoint Designer workflow. I can the data of current site loop through all the data, but when I make service call to the Top level site from the SubSite then it gives me the "Access denied. You do not have permission to perform this action or access this resource". How to solve this particular issue. I have tried this with the Admin account.
