I'm trying to figure out how to get an application insights access token but the link I've found seems to be broken:
https://dev.applicationinsights.io/documentation/Authorization/API-key-and-App-ID
Is there a better link to look at? I need the access token in order to send up a query for ADO to generate some charts on my dashboard to use for better querying of data.
I'm not sure what to do.
You can still create query API keys. However, they are deprecated and should not be used anymore for new scenarios.
Instead, you should move to AAD-based authentication.
From the Azure Portal on your AppInsights resource:
