You define the API endpoint, specify the parameters Captain should extract from the conversation, and describe what the tool does.

This gives Captain more context when it needs it useful when your responses depend on who the customer is.\u003C/li>\u003Cli>Auto-resolve gibberish and no-intent messages: If a conversation has been idle and the last message was gibberish or had no clear intent, Captain can now auto-resolve it instead of leaving it open.\u003C/li>\u003Cli>Improved hand-off behavior: We refined the hand-off prompt so Captain is less likely to escalate when a conversation is being auto-resolved. Separately, Captain now skips the hand-off entirely if the conversation is no longer in a pending state.\u003C/li>\u003Cli>Agent name in widget bubble: When Captain replies and the conversation is unread, the widget now shows the assigned agent's name instead of a generic label.\u003C/li>\u003Cli>Bulk manage Captain documents: You can now select multiple Captain knowledge base documents and delete them in bulk.\u003C/li>\u003C/ul>\u003Cp>\u003Cstrong>Webhooks & API\u003C/strong>\u003C/p>\u003Cp>We made several changes to how webhook payloads are structured, aimed at making integrations more predictable.\u003C/p>\u003Cul>\u003Cli>Raw message content in payloads: Webhook payloads now send the raw message content instead of channel-rendered HTML.

Previously you'd see the failure but not what was being sent.\u003C/li>\u003Cli>Better error messages on API channel creation: When creating an API channel fails, the error message now reflects the actual backend error instead of a generic failure.\u003C/li>\u003Cli>Webhook on agent bot assignment: Assigning an agent bot to a conversation now dispatches a webhook event, so bots respond correctly even when assigned after the conversation has started.\u003C/li>\u003C/ul>\u003Cp>\u003Cstrong>Channels & Integrations\u003C/strong>\u003C/p>\u003Cul>\u003Cli>Configurable Dialogflow language: You can now set a language code for Dialogflow queries, with support for auto-detection.
