Inquiry on Optimizing API Calls for Buyer Details

Hello,

I am posting on the SP API Seller Forum with a question regarding the Amazon SP API invocation methods. Currently, when extracting order information, we are controlling the process using exponential backoff and asynchronous calls. However, when retrieving detailed information for a single buyer, we are calling three separate endpoints—buyerinfo, address, and orderItems—which is causing significant delays. We have thoroughly reviewed the documentation, but we are wondering if there is a faster method to perform these calls.

Thank you for your assistance.
