In order to use the Amazon Product Advertising API you need to create your personal API keys.
If you have any issues using your previously created keys, you can use our “Amazon API Key Checker” in order to validate your keys. Your input will only be used for sending a request to the Amazon Product Advertising API and will be destroyed afterwards.
Our suggestion: Create a new pair of keys only for this validation and deactivate them afterwards.
