Thank you for your response.
Yes, I’m saving my requests in a collection. As I understand it, a collection does not store data like API keys, or am I missing something?
In the DataFlex database programming language world in which I do most of my work, we have the concept of Workspaces. With workspaces, we can work in only one workspace at a time. In that context, I’m expecting when working with one collection, that data from another collection would not intrude on another collection.
Back to my original question, why does the API key (password) from my MailChimp collection intrude/over-write the key in my legalwareContacts collections? My impulse is to call it a bug, but because I’m just beginning with Postman, I’m open to it just being my inexperience.
