ChannelGrabber enforces a 20 API requests per second policy. As a result, you may see the below error message, or similar "API Limit errors" when shipping multiple orders at the same time.

Too many requests have been made (limit is 1 request(s) per 1.00 second(s)),

If the ChannelGrabber API limit is hit by Shiptheory while downloading orders or updating tracking numbers, Shiptheory will retry the operation in the next 30-90 seconds.
