Currently, only deleted collections can be recovered from the trash, not folders or requests.
You have a Postman Basic, Professional, or Enterprise plan
You can use the changelog to revert a collection and restore it to any previous point in time.
Note: The feature is not retroactive, so you won’t be able to recover your folder using the changelog if you upgrade from a free to a paid plan.
You have a Postman Free plan
The changelog isn't accessible on a free Postman plan.
A possible workaround to rebuild your folder more quickly is to search for requests from deleted folders in your history and add those requests to a collection.
