How do I answer buyer questions?

Use `get_questions` to list them, then `answer_question` with the question ID and your response text.

Why is my reputation yellow or red?

Use `get_metrics` to check your specific performance indicators. Late shipments, cancellations, and negative claims usually lower your reputation level.

Can I see past conversations with buyers?

Yes, use `get_messages` with the Order ID to retrieve the message history for that specific sale.

Can AI auto-respond to buyer questions?

Yes! You can set up workflows that fetch new questions with `get_questions` and automatically respond using `answer_question`. Just be mindful that each response is final and visible to all buyers browsing the listing.
