Amazon limits the number of requests that we can make on behalf of a user within a time period (i.e the rate of requests made), and if you exceed this threshsold,further requests they will be throttled. To prevent requests from getting throttled, OrderCup has implemented a Bulk Update Request on the Packges tab that allows your to do a Bulk Update a few times a day. The bulk update updates the shipping information for all orders for the selected date that have not already been updated.
To use this feature, use the Bulk Update feature as described in the article below.
