Obtaining order information and purchase invoices directly from an AMAZON API as a buyer

Amazon does not provide a public API for buyers to directly access their order and purchase invoice information. The Amazon APIs that are available for accessing order information are typically designed for sellers to manage their sales on the platform. If you need to automate the retrieval of this information for business purposes, you might consider using web scraping techniques, although this approach can be complex and may violate Amazon's terms of service.
