Please be aware that there has been a recent change of implementation regarding Amazon’s Product Advertising API limit.
According to Amazon Product Advertising API document, the allowed initial usage limit per day is 8640 requests and the limit for each account will be based on the revenue performance of your Product API during the last 30 days. They also mentioned that if your account hasn’t generated any referring sales using Product Advertising API in the last 30 days, your account will lose access to Product Advertising API.
Our Amazon Import feature sends requests using Amazon Product API and once you’ve reached the limit, you will receive this error notice.
AWS Access Key ID:... Você está enviando solicitações muito rapidamente. Tente novamente enviar suas solicitações em um ritmo mais lento.
Sugerimos o uso moderado do recurso da Amazon e a ativação do cache de resultados de pesquisa (ThirstyAffiliates > Configurações > Importação da Amazon) para reduzir o número de solicitações usadas no limite da API do produto.
In case you lose access to Amazon Product API, you’ll regain access once your account begins to drive referring sales again.
