Amazon Product API - Error! TooManyRequests on AMS ScratchPad

Question

I was approved for the Amazon Product API, and am doing a couple test calls in ScratchPad, and it continually comes back with the error:

Error! TooManyRequests The request was denied due to request throttling. Please verify the number of requests made per second to the Amazon Product Advertising API.

I've never once received a good response. I have chatted into their support for over a week, and no one there is any help, and just says 'it looks fine, I don't know why you're getting that response'

• I've only made about 10 calls total, via ScratchPad. Maybe only about 3/day.
• I have more than 3 qualifying sales in the last 30 days.
• Keys are more than 72 hours old. Even made a second pair of keys, waited 3 days, and they still don't work.
• Applied for API usage and keys about 2 weeks ago, so hasn't been disabled due to 30 days of no sales attributed to API.

Here is what I'm inputting into ScratchPad:

Answer 1

The issue isn't fixed yet with the scratchpad. It is well known that there is no solution for that problem at the moment. There are 2 good manuals out there for other Amazon affiliate usages: Workaround 1 and Workaround 2.

I think you should switch like in the Workarounds described. The API can't handle that by now.

I know that isn't the answer you want to here, but it could help others facing the same issue. I will keep the answer updated, if a final solution is coming up.
