Group limitations

With groups, you send and read messages and receive webhooks when a group changes. Group administration (creating groups, managing members, changing settings) is not offered.

Sending messages to a group requires the Business plan or higher

Receiving group messages, listing and looking up groups through the API (GET /v1/numbers/{ref}/groups) and receiving the 10 lifecycle webhooks work on any plan. Only sending to a group_id (message or typing indicator) requires the groups:messages feature, available from the Business plan up. On the Free and Lone Wolf plans the send is refused with 402 feature_not_available. See Send to a group, Typing indicator in groups and Quota and usage.

Public identifier

grp_{hex32} (32 hexadecimal characters). The WhatsApp identifier (120363...@g.us) never appears in the API or in webhooks: only the Turbo Notify format.

Quota and rate limit

A message to a group counts as 1 recipient in the daily recipients limit, no matter the size of the group. It does not count against the contact quota.

Recovery

If you lose the name of a group (for example, if a webhook was not delivered), wait for the next message received in the group: the message.received webhook carries to.name (the group name). You can also call GET /v1/numbers/{ref}/groups/{id} at any time.
