How to use a Linked Service in Azure Data Factory in a Web Activity

Question

I have setup a Linked Service in Azure Data Factory to use a Copy Activity to access Graph APIs, which require use of the OAuth protocol, which works fine. I now want to extend that to use the same Linked Service with a Web Activity. But in tests, it is returning "Empty Token"; Am I missing a (simple) config. option, or am I misunderstanding something?

Earlier, I used explicit Token fetch, which also works fine, but as my queries will - in Production - take longer than the (default) Token TTL, I did not want to have to implement Token refresh, at least not if the Linked Service will handle it for me.

Hi @John Dawson

You are indeed missing a simple configuration. From my testing, this linked service also works for web activity, you just forgot to choose the authentication type in the web activity.
