The 3E API provides low level access to the 3E Financial System application logic layer for the decoupled 3E User Interface.

Data Insights API allows you to expose OData based REST API from database objects like table(s) and view(s).    

The Billing API provides functionality to upload new LEDES invoices, including uploading attachments. This is equivalent to taking the action with the Tracker user interface,  "Post invoice".  The API also supports downloading an invoice and its attachments after an invoice has been uploaded.   You will also be able to get a list of matters you have access to.
