How to create an integration column?

I am trying integrate our app with by using custom trigger and CREATE AN ITEM WITH MAPPING. Can I know how will I be able to create an integration column along with this flow of creating an item?
Also, will I be able to update an item using the recipes only, without making use of API?

Hey @prsparrow - I believe you would be able to update the item using the recipes only.

As for the integration column - let me check in with the team on this and get back to you.
