The access token received from the authorization server in the OAuth 2.0 flow.
The recipient's user ID for a 1:1 conversation, or a group conversation ID (prefixed with 'g'). Identifies the conversation target. Accepts three formats: (1) a recipient user ID for 1:1 conversations (e.g., '1215441834412953600'), (2) a legacy 1:1 conversation ID with two user IDs separated by a dash (e.g., '1215441834412953600-1603419180975409153'), or (3) a group conversation ID prefixed with 'g' (e.g., 'g1234567890123456789'). The server constructs the canonical conversation ID from the authenticated user and recipient when a single user ID is provided.
