Hello @kai-3850,
The key difference between GetMyMessages and GetMemberMessages lies in the types of messages they retrieve and the details they provide:
GetMyMessages: This API call is designed to retrieve a variety of messages sent to a user's My Messages mailbox on eBay. These messages can include notifications from eBay, messages from other eBay users, and system messages. It's useful for managing a broad spectrum of communications in a seller's eBay mailbox.
GetMemberMessages: This call specifically retrieves messages that buyers have posted about your active item listings. It focuses on communications related to specific transactions or item inquiries, making it particularly useful for managing buyer-seller interactions regarding listed items.
As for why users send messages, they typically do so to inquire about products, resolve issues, or communicate transaction-related details. The reason some messages can be obtained by GetMemberMessages but not by GetMyMessages could be due to the specific nature of the messages. GetMemberMessages fetches messages related to item listings directly, which might not be captured by GetMyMessages if they don't fall into the general categories of messages it retrieves.
Best Regards,
eBay Developer Support
