Create and send a poll in a chat

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.

Path ParametersExpand Collapse
chatId: string
formatuuid
Body ParametersJSONExpand Collapse
poll: object { options, idempotency_key }

Optional key to deduplicate the poll creation.
