Is it possible to reference/filter by project custom fields from a task-level API search request?
Since it doesn't seem to be possible to pull data directly from a report, I am trying to use the API to get all the tasks that fit certain conditions, and one of those conditions is that a custom field, called Date Booked, is not null. However, when I put "project:DE:Date Booked_Mod=notnull" into the URL, I get this error message:
{"error":{"message":"Invalid Parameter: Search Parameter value \"project:DE:Date Booked\"","title":null,"msgKey":"exception.attask","attributes":[""],"code":0}}Is what I'm doing possible, and if so, what am I doing wrong? Either way, please let me know.
Thank you.
