This is a script for hosted Jamf Pro that returns all the installed apps across your fleet and sorts them by most installed to least. Update the variables $jamfpro_url and $api_pw in the script for your environment. It should return results up to 2000 computers. If you need more, you’ll have to add pagination.

The basic concept is to call the /api/v1/computers-inventory?section=APPLICATIONS endpoint, loop through and add all apps and versions into a hash (dictionary) and then print and sort the results.

It takes your Jamf username and password and converts it to a base64 string that you put in the $api_pw variable and then that generates a bearer token for the additional calls. The invalidateToken function at the very end, revokes the bearer token.

To get the base64 string you just put this into terminal and paste it into the $api_pw

printf "jamfUserName:JamfPassword" | iconv -t ISO-8859-1 | base64 -i -

This script is helpful to get an understanding of all the apps installed in your fleet, including most and least popular Apps. I use this to also help determine what Apps we should prioritize in patch management.

Note: Change out jamfUserName and JamfPassword with a user that has at least read only privileges in jamf. Make sure to keep the “:” inbetween the variables.
