Hello,

I would break down such process into steps:

A) You'll need to send API request to get Dataframe for celonis users on hourly basis (put it on schedule). More details can be found here:

B) You'll have to authentificate to MS graph in order to:

1) Create excel file if that not exist

2) If excel exist: load it and compare with current users DF. If there's difference - then you can add new row to that excel fie.

More on MS graph authentication can be found here: https://www.celopeers.com/s/question/0D50700001g8miRCAQ/connection-to-sharepoint-site-to-get-a-custom-file-and-then-use-it-in-data-model

I think there's no possibility to trigger python script by updating user details - you can only schedule it very frequently to track these changes every hour or so.
