https://developers.wrike.com/api/v4/contacts/#query-contacts
On Wrike's developer site, it lists a custom field filter, I have never been able to get this to work or identify a path forward.
The goal is to query profiles.email or primaryEmail, to look up a Wrike Contact ID by Email.
I have seen numerous posts saying the only way to filter a contact like this is to GET all contacts and filter after pulling everyone.
The issue is that we have over a quarter of a million contact ids, its way to much data to filter in this fashion.
But at the same time Wrike's API Documentation makes it seem like its possible?
It asks about finding the customFieldId, so how do I look up the customFieldId for profiles.email or primaryEmail? its almost like its not supposed to be there?
