Hi Cheryl,
It is not possible to get all the database in one API call. You can get data from a specific table by using the https://api.clarizen.com/V2.0/services/data/Query endpoint. Example:
POST https://api.clarizen.com/V2.0/services/data/Query
This would get the first 1000 projects matching the filter (DueDate<'2021-01-01' AND StartDate>'2020-01-01') and return their Name and Work.
Documentation: https://api.clarizen.com/V2.0/services/data/Query
I hope this helps.
Roland
