Amazon scrapers take your geo input and turn it into "Deliver to" address preference on Amazon. There are two ways you can specify the delivery address for Amazon:
For locations within the native country of the Amazon marketplace, please send a zipcode/postcode. For example, if you want to see "Deliver to New York 10005" on your Amazon.com result, please send "geo": "10005", "domain": "com" parameter. If you're not particular in terms of which place within the country you would like to set the delivery location to, just choose a random zip/post code, but don't just set it to country name.
For locations outside the native country of the Amazon marketplace, please use a 2-letter country code. For example, if you would like to set the delivery location to France on Amazon.com, please send "geo": "FR", "domain": "com".
Any single Accept-Language header value without q-factor. See this page for examples.
Only used with Callback. Specify the URL to which we should POST the job completion notification.
