Harvest

Last updated on Jul 03, 2025

Harvest is a cloud-based time tracking and invoice generation software designed for businesses of all sizes. Harvest is easy to integrate with the other software for your team to track time effortlessly. Businesses can use Harvest for time tracking, expense tracking, project management, billable hours tracking, task assignment, invoicing, scheduling, and more.

Harvest authenticates API requests from Hevo to access your account data with HTTP Basic authentication.


Source Considerations

  • Pagination: Each API response for each Harvest object fetches one page with up to 100 records.

  • Rate Limit: Harvest imposes a limit of 100 API calls per 15 minutes. If the limit is exceeded, Hevo defers the ingestion till the limits reset.


Limitations

  • Hevo does not capture information for records deleted in the Source objects.

  • Hevo does not provide you with the option to select the historical sync duration for loading historical data. All the historical data in your Harvest account is loaded.

  • Hevo does not load data from a column into the Destination table if its size exceeds 16 MB, and skips the Event if it exceeds 40 MB. If the Event contains a column larger than 16 MB, Hevo attempts to load the Event after dropping that column’s data. However, if the Event size still exceeds 40 MB, then the Event is also dropped. As a result, you may see discrepancies between your Source and Destination data. To avoid such a scenario, ensure that each Event contains less than 40 MB of data.
