Get your Harvest Account Id

Harvest requires that you pass your account ID in a header when making requests to the API.

As Harvest doesn't surface this ID in their web interface, we'll get the account ID through the API.

Part 1: Fetch Account ID through the API

1. In API Connector, click Create request
2. Enter the following URL as a custom request: https://id.getharvest.com/api/v2/accounts
3. Under Authentication, choose Harvest. If you haven't already, you will need to click the blue Connect button.
   
4. Choose an output sheet and click Run.
5. You should see your account ID(s) returned into a sheet, under the field name accounts.id

Part 2: Use the Account ID in Requests

This account ID should be entered as the Harvest-Account-Id header in any API request to Harvest.
