Hello there

Our project aims to create a marketplace app for Zendesk chat.

Our objective is to automatically give a response to users based on their inquiries whenever they post messages using the web chat widget.

首先,我们试图accomplish this by manually setting up a webhook.
Conversations Integrations (Webhook subscriptions - Conversation Message) can be found in Zendesk Admin > Apps & Integrations> Integrations > Conversations.
With this approach,we have accomplished our objective.

Then, we began to develop an app (which runs continuously in the background and has NO UI). But we were unable to locate a suitable event.
