The problem I've had with Postman is the sharing between team members. Everyone needs to add new requests, edit (locally) but sometimes sav the edits back to the collection.

Someone has to modify the auth script and have it update for everyone.

I thought this is what the tool is designed for, but it's been a nightmare. Team members have to wipe their environment and start again regularly. I want to think that we've completely mucked up using it but I'm not sure it's us and not the tool.
