Create and send a poll in a chat

client.chats.polls.create(stringchatID, PollCreateParams { poll } body, RequestOptionsoptions?): PollEnvelope { chat_id, created_at, message_id, 3 more }
POST/v3/chats/{chatId}/polls

Create an iMessage poll in an existing chat and send it. Polls are iMessage-only.

The chat must already exist — a poll cannot be the first message of a new chat (use POST /v3/chats for that). Options are add-only and immutable: you can add options later via POST /v3/messages/{messageId}/poll/options, but never edit or remove them.

ParametersExpand Collapse
chatID: string
formatuuid
body: PollCreateParams { poll }
poll: Poll

idempotency_key?: string
