Set zoom per host programmatically

[Theron]

I need a way to set the zoom level for a particular host programmatically (on Windows). I've found the relevant JSON key in the %USERPROFILE%\AppData\Local\Google\Chrome\User Data\Default\Preferences file. An example from my machine looks like:

"partition":{"per_host_zoom_levels":{"14695981039346656037":{"example.com":-1.5778829311823859}}}

My question: The first number in that sample (14695981039346656037) seems to be the same across machines, but I'm guessing it changes with Chrome versions, as other people online who have tried to do this give different numbers. And that "partition" key isn't present at all on a machine that hasn't had a custom zoom set yet. How can I detect or generate the correct number when applying this policy to new machines? Thanks to anyone who can help!

You should not fiddle with the Preferences file. It can change at any time.

The right way to do it is to use extensions, either an existing one, if you find something suitable, or to create one. There is a zoom API.

Could you please point me to the documentation on the zoom API you mentioned? I'm having trouble finding it. Thanks!
