Postman always defaults to "Auto" response type. I'm working with an API that always returns Content-Type:text/plain even though it should be JSON. Is there some way to force Postman to always display responses as pretty-printed JSON for a whole collection?
Usually Postman auto detects the response format using Content type header, specified in header for every API request.
You can also specify to display auto select JSON in
Settings -> General -> Language Detection to JSON
