Get a guest link

POST /v1/chats/:dialogId/guest-links

Returns your guest link to the chat and creates it if the link does not exist yet. A person outside the Bitrix24 account joins the chat through the link URL, and each member has their own guest link.

Parameters

Parameter Type Required Description
dialogId (path) string yes Dialog ID: chatXXX for a group chat, a numeric user ID for a private chat, me — your personal dialog. List — GET /v1/chats/recent

The request takes no body: body fields and query parameters are rejected with 400 INVALID_PARAMS.

Known specifics

Automatic chat membership. The call can make the key owner a member of a chat that allows auto-join, even if the link operation is subsequently refused. A read-only key is blocked before Bitrix24 is called.

Links count toward the invitation limit. Every new guest link, including regenerated and revoked ones, counts toward the author's limit of 10 guest links per hour, which is checked by invitations by email and by SMS.
