I have a private API key that I am using to authenticate API calls to the v1-v2 legacy version of the API.
The API key works when I call the following endpoints:
But, when I call this endpoint: "v2/group/LIST_OR_SEGMENT_ID/members/all" I get a 403 response with a message "The API key specified is invalid."
How can this API work for all attempted endpoints except when trying to get the members of a list or segment?
