Rate Limiting and Concurrency

While there are no rate limits on the number of requests you can make per minute, there are concurrency limits based on your subscription plan:

  • Free Account: Maximum of 1 concurrent request.
  • Basic Plan: Maximum of 8 concurrent requests.

To check your current concurrency limits:

  • Log in to your HarvestAPI account.
  • Navigate to your Subscription Page.
  • Review your plan details to see your concurrency limits.

Exceeding your concurrency limits should usually put your next requests in a queue, though request rejection is also possible (in case of too many requests in the queue). Ensure that your application manages concurrent requests appropriately to stay within your plan’s limits.
