App with users - how to create API access to that users?

I have an marketplace app and I am looking how to enable my app users to access over API and post offers. How to do that?

Can anyone help me with that? How to start? I am searching but didnt found anything similar…

Thanks!

You should create a workflow API (aka public backend workflow) to handle new posts to be added to your marketplace. Then create a way for users to authenticate as themselves so they can use that API key returned to authenticate into your public API.

Also add , generate seperate api toeken for user to call you backend API workflow.

you can generate a API token specificly for each user by usisng login action in backend api , this will return a token whcih is specific for that user.
