The number of API calls per hour is based on your plan and employee count. By default the following rates will apply:

Rate limit per minute
Blossom and Garden
number of  Subscribed Employees
2 times the number of Subscribed Employees

For example, let's say you are part of the Blossom plan and subscribed to the 200 employee bucket, you are rate limit is 200 = 200 calls/hour. 

If you are looking to increase your API limit, please drop an email to with a complete description of your use-case and we'll help you sort this out.
