RequestThrottling issue in Amazon MWS API

Question

I am testing API Sample of Amazon MWS API in C# for submit feeds however after setting AWS Secret key , access key etc. in code i am getting error of RequestThrottled , so t

Answer 1

As per Amazon's API reference the SubmitFeed operation has a maximum request quota of 15 and a restore rate of a request every 2 minutes. This means that you're allowed to make calls to this operation in burst of 15, but after this you're throttled for 2 minutes, until Amazon allows you to make another request. You can find this better explained in their developer guide where they describe better how they make use of the leaky bucket algorithm.

Probably there isn't anything wrong with your feed, but because you made too many requests (probably more than 15) you got throttled. My advice is to build your code in such a way that you take into consideration Amazon throttlening and have a back-off algorithm when you're being throttled (like come back after a "restore rate" period, specific to the type of call you're doing). Also, keep in mind that another limitation MWS has is of 10000 requests per hour across all type of calls.
