Data Studio - 社区连接器 - 如何添加用户令牌？

Question

I want to connect to a REST API. This works great with google sheets and scripts. But now i don't know how i can insert the token required. It needs to be in the header of the GetRequest so i tryed this code. But when i launch trough manifest file i get an error:

There was an error caused by this connector.

My script

As you can see i try to pass the token within the getData(). Somy knows the solution?

Answer 1

The official Authentication guide explains how you can get the username and token from the user, store them in script properties, and then use them in your code. You will need to create the setCredentials() , isAuthValid() , and resetAuth() functions as well.
