You will need to use either a System Account using HTTP Basic...or register an Add-On and leverage OAuth to query the API. Unfortunately, you can not leverage the same clientId/clientSecret to access the Core API by itself. Does this help answer the question?
Hi Ryan, actually I've both system account for data export service and REST API. My problem is I don't know how to collabrate result of data export service and REST API to find the content detail of an user activity. For example, I can get the latest user downloading file activity from data export service by query like this:
In the response result, I can get some information like user, action type, time, related object id. Then I want to get the downloaded file content using REST API such as:
But I don't know how, I've tried using object id, container id, etc .. to do the query, but I can not find the result that I want.
