Permissions for Test connection of ADF Linked Service

[successhawk]

What is the minimum permission that the Service Principal needs in order to test connectivity? I am currently getting 403 error.

This is the endpoint you must have access to:
https://management.azure.com/subscriptions/$SubscriptionID/resourcegroups/$ResourceGroup/providers/Microsoft.DataFactory/factories/$DataFactoryName/testConnectivity
Unfortunately this is not documented API, so we don't know if any exact permission is needed.
However, I'd check if you have access to the endpoint and send GET request.
