What Harvest Reports (BYOK) is for

Harvest Reports (BYOK) lets an AI assistant read your own Harvest Reports data through the Harvest Reports API with a key you supply (personal access token). Read-only: 10 tools (time_report_clients, time_report_projects, time_report_tasks, time_report_team, expense_report_clients, expense_report_projects, expense_report_categories, expense_report_team, uninvoiced_report, project_budget_report). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.harvestapp.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Harvest Reports. Harvest Reports and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "How many hours did we track per client in Harvest this year?"
  • "Which Harvest projects had the most hours this quarter?"
  • "How much Harvest time went to each task type this year?"
  • "How many hours did each person log in Harvest last month?"
  • "How much did we spend on expenses per Harvest client this year?"
  • "Which Harvest projects have the highest expenses?"

BYOK key

You bring your own Harvest Reports personal access token (https://id.getharvest.com/developers). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.harvestapp.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources
