I want to bring back the latest Events and Topics, but only the ones that a given user is Authorized to see. For both of these endpoints, the only way to do this is to use an oAuth access token.

I don't actually have a third party service that I want to integrate with, the script simply needs to run on my server. I want to get a token to impersonate the user, so I can get this information back. What's the easiest way to generate one of these tokens?

Hi,

Depending on what you're doing with this data, you might want to take a look at external widgets instead: 

 

This would allow you to embed that kind of data with the proper permissions into your chosen page.
