Explore the Harvest API data model

See how the various Harvest endpoints relate to each other, using our handy Entity Relationship Diagram

Try our interactive ERD Or, browse below

Pulling data from the Harvest API is only the first part of your reporting. You also need to understand the relationships between different endpoints - something that APIs typically fail to convey.

At SyncHub, we not only sync your Harvest API endpoints down into a reportable format, we also describe their relationships (e.g. in terms of foreign keys) so that you can quickly get a grasp of your data and how it fits together. This page is intended as technical documentation of these relationships.
