Export all collections in postman
In Postman, open the wrench icon, then settings, then data, then Download. See images below:
You can export all APIs, Collections, Environments, Globals, and Header Presets to a single data dump zip file.
To open the Data
tab in the app (v8):
Settings > Data Tab > Export Data
Selecting Export Data
will take you to the area where you can download all data from your account.
You will receive an email when the data is available to download, depending on the size of the data set, refreshing the page will cycle through the download status and eventually show the Download
button.
Importing the data zip file back into a Workspace can be done by selecting the Import
button and selecting the file.
You will see a preview of the files that you're about to import, before importing them into the Workspace.
