Export your Postman data as JSON files, create a project in Insomnia, click Import and select the files to import.
This how-to guide requires a Postman export. You can either export environments and collections individually (this can be useful if you want to import them into different Insomnia projects), or all at once from:
In Insomnia, click the + button in the left panel to create a new project in which you’ll import your Postman data. Select your preferred project type, in this example, we’ll use Cloud Sync.
In this example, two collections and an environment are imported. Once the import is done, you’ll see your content in the Collections and Environments sections. In the case of a Cloud Sync project, the imported data is automatically synchronized. You don’t need to do anything else to share it with other members in your organization.
If your collections use variables from a global environments, you’ll need to click Base Environment and select the global environment in each collection.
Will my Postman pre-request and post-response scripts work in Insomnia?
Yes, most Postman scripts can be automatically converted by Insomnia during the import process. For more details, see Migrating scripts from Postman.
Can I import mock servers from Postman to Insomnia?
No, mock servers can’t be imported, they need to be recreated manually in Insomnia.
