The number of API calls per hour is restricted to 1000. If your API request is received after the limit has been reached, freshservice will give you an error response. The "retry-after" value in the response header will tell you how long you need to wait before you send another API request.
For more details refer to our API v1 documentation: https://api.freshservice.com/
Freshservice accounts created on or after 01-Sep-2020 will use minute-level rate limiting. The limits vary based on the freshservice plan. Certain API operations also have sub-limits within the overall limit. This limit is applied on an account-wide basis irrespective of factors such as the number of agents or IP addresses used to make the calls.
Accounts created before 01-Sep-2020 will eventually be migrated to minute-level rate limiting. The previous limits would continue to apply until the migration is completed.
