I'm wondering if there is a way to bring up a GUI (jamfhelper, cocoadialog, etc) to give a device an already created EA. As mentioned, the EA is created, I just need a way for a technician who is setting up the computer to assign it to the right EA so that it drops into scope for some policies to run based on the EA. The EA I created has the following characteristics: Data Type: String, Input Type: Pop-Up Menu . I then have a few items in the dropdown to choose. I'm hoping to be able to assign one of those dropdown items directly from the computer.

You need to be careful about passing credentials into scripts as it's not a safe practice
So I have a suggestion that might work and something we use here during the build process. When the ADE process starts it brings up DepNotify and asks the user for certain information (computer name, user assigned to, location, and persona). What I did was I had the script default write those values to a plist file.
So you can create a GUI to get the data and send it to the plist file. Then you can use a EA that uses a script to read the information from the plist file.
But I do think that giving techs access do to do it themselves might be faster.
Does anyone have this same script or something similar which is using basic authentication changed over to token authentication?
For starters I have, the following ground work to get the token but I'm not sure how to use the token to authenticate to the API so I can run scripts similar to the ones shared on this thread.
#!/bin/bash
username="username_here"
password="password_here"
URL="https://someplace.jamfcloud.com"
# created base64-encoded credentials
encodedCredentials=$( printf "$username:$password" | /usr/bin/iconv -t ISO-8859-1 | /usr/bin/base64 -i - )
# echo encodedCredentials: "$encodedCredentials"
# generate an auth token
authToken=$( /usr/bin/curl "$URL/api/v1/auth/token" \\
--silent \\
--request POST \\
--header "Authorization: Basic $encodedCredentials" )
# echo authToken: "$authToken"
# parse authToken for token, omit expiration
if [[ $(/usr/bin/sw_vers -productVersion | awk -F . '{print $1}') -lt 12 ]]; then
token=$(/usr/bin/awk -F \\" 'NR==2{print $4}' <<< "$authToken" | /usr/bin/xargs)
else
token=$(/usr/bin/plutil -extract token raw -o - - <<< "$authToken")
fi

Ironically, I was looking at that script myself today trying to update my old auth scripts. I got that same error, I suspect there might be another xml file in tmp with that name (since it's just a number). I updated my code to "/tmp/$Jamf_EA_{EA_ID}.xml" in a few spots and it seems to be working now (although I'm getting a HTTP 401 return code trying to get the token). Slow progress is still progress, right?
Edit:
My credentials were setup like this:
encodedCredentials=$(echo "$APIUSER:$APIPASS\\c" | base64)This worked fine when I ran the script locally, but failed when running through my Self Service policy. When I swapped in the `printf` command above, I got the prompt below and clicking that worked.

@PhillyPhoto , did you ever get this to work?
