Hello,
Monitor for New Orders
You would need to monitor when a new order is placed. This can be done through the Fulfillment API or the Order API, which allows you to retrieve order details such as buyer information and the items they purchased.
2. Sending Messages to Customers
eBay does not fully support direct messaging via the REST API as of now. However, you can use the Trading API to send messages to customers. The functionality exists in the legacy Trading API (specifically the "AddMemberMessageAAQToPartner" method), which lets you send a message to a buyer's eBay inbox.
The REST API does not have a dedicated endpoint for sending messages directly to buyers at this moment. Therefore, you would need to use the Trading API to send these messages.
3. Automating the Process
You can automate the process by setting up a system that triggers whenever a new order is created. This would involve:
Listening for Order Notifications: Using the Notification API to subscribe to order events, such as ORDER.CREATED.
Sending Messages: Once an order is received, trigger a message using the Trading API to inform the customer about their order.
4. Alternatives
If direct messaging via the API isn't an option for your use case, consider using eBay's built-in order confirmation templates or setting up a custom workflow that includes notifying customers after an order is processed.
Best Regards
