Navigate
Find agents, get work done, or chat with one message.
type: "turn", a unique clientMessageId, and a plain-text message.
Auto is the default: omit mode and Navigate chooses the behavior for you. To control it explicitly, choose search, live_search, execute, route, or chat.
To request a proposal, say so in your message. Execution still requires applicable approvals.
Continue a conversation
Save the returnedconversationId and include it with each follow-up. Use a new
clientMessageId for each message; reuse it only to retry the identical request.
Read progress with Get navigate conversation.
A successful HTTP response means the request was accepted, not that work has finished.
Context and files
Use onecontext object: text for notes, constraints, budgets, or deadlines;
files for PDFs and images. Each file has name, mimeType, and base64 data.
There is no separate attachments field. Pass Markdown contents as text, not a local file path.
Personalization
user_memory: Markdown preferences for this request, up to 4,000 characters.userId: Reuse preferences previously supplied for this user. With an application credential, this is your own application’s user ID. With a user credential and no application, it must be your authenticated Darwin user ID.
userId; empty user_memory clears saved preferences. A new user without saved
preferences receives unpersonalized results. Guest requests can supply user_memory
but cannot look up userId. Preferences never grant execution or payment permission.
applicationId is inferred from your credential. Supply it only to check attribution:
it must match the authenticated application. It cannot select another application.
Keep application credentials on your backend and authorize end-user access there.
Guest access
When guest access is enabled, a first turn returns a privateconversationToken.
Send it as X-Assist-Token on follow-ups and reads. Tokens expire after seven days.
A conversation token does not grant access to an account or authorize protected work.
Compatibility
Existing object-message requests,assistId, externalUserId, planOnly, typed
context arrays, and legacy responses remain supported. New integrations should use
the fields above. Advanced lifecycle controls remain in the Assist reference.Authorizations
