This is great! I had been using Retool (free), which is a low code no code solution that allows creation of forms that can connect to apis/databases very easily, but they had also supported workflows to call APIs in a very very similar way. I like the idea of having this directly contained in my postman collection instead.

Can you provide a link for where to purchase that helmet/light?

Great tutorial. However, it's a bit out of date. Many blocks are deprecated. Possible to update? Thanks.

This is freaking awesome! I'm trying to use it to automate some authentication steps. I think it would be awesome if there was a manual step for it to wait for the user's input, such as a text, or a press of a button.

Say for example I'm handling a One Time Password setting in which I send the authentication to a server, the server replies back with a code in my phone and I need to write it into the app. I'd be awesome if I could just write in inside Postman's flow.

Hey, this feature is crazy. BUT. where can I find documentation on it? or examples? I'm guessing its so new that no examples are doesnt exist yet. but still, I cannot get some features how they work.
Please please advice.
Thanks

Nice! Are there more videos showing how to use Flows? A straight-forward example for me would be how to loop over requests in a paginated API to get ALL answers instead of just the first n. Firthermore, how would I loop over a JSON array from a result, pick data, form a new request with that data and send that request and export data from that to, let's say, a CSV file? Is something like that doable with Flows?
