Currently, only deleted collections can be recovered from the trash, and not folders or requests.
You have a Postman Basic, Professional, or Enterprise plan
Use the changelog to roll back a collection and restore it to any previous point in time.
Note: The feature is not retroactive, meaning that you won’t be able to recover your folder by using the changelog if you upgrade from a free to a paid plan.
You have a Postman Free plan
The changelog is not available on a Postman free plan.
One possible workaround to rebuild your folder faster is to look for the requests from your deleted folders in your history and add requests from your history to a collection.
