post https://api.timekit.io/v2/findtime/filtercollections
You can save a collection of filters if you want to reuse them in a FindTime request. This endpoint takes a JSON structure like the one you would normally pass to the "filters" key in FindTime.
In your FindTime request, use the filtercollection_id
to pass the ID of your new filter collection and those filters will be taken into account when calculating availability.
Filters available
Please see this reference for all filters that you can use
