# Author Page Parameters
`GET` `/request`
The Author Page Parameters are applicable when making a request with `type=author_page` to retrieve data from the authors page single author on Amazon - the author is specified using either the author `asin` and `amazon_domain` parameters or the `url` parameter (where the `url` parameter contains a link to an Amazon authors page). The parameters should be appended as querystring parameters to the Product Data API `GET` HTTP request.
Author Page data is retrieved from the [author page](https://www.amazon.com/kindle-dbs/entity/author/B000APVZ7W) for a single author on Amazon.
For example, to request data from the authors page for the author-ASIN `B000APVZ7W` on `amazon.com` the request would be:
