Insomnia is an open-source desktop application for creating APIs. You can export requests, environments, and other data from Insomnia, then import them into Postman.
In Postman, select Import > Migrate to Postman > Other API Clients.
Select files or folder then select the files or folder you want to import.
Select Start Migration. Postman checks if the selected files are valid Insomnia files.
If the files are valid, you can select Start Migration. A window appears showing the migration’s progress. When the migration is complete, select Dismiss.
You can also drag files and folders into the import window.
