WhatsApp

Add participants

Add participants to a WhatsApp group. Maximum 8 participants per request. A group holds at most 8 participants in total (a Meta limit), so later requests cannot grow a group past 8. Meta documents groups as invite-only, so people normally join through the group's invite link.

Not available on Coexistence numbers. Requires a Cloud API-only number.

Billing: Request; paid actions are priced in credits (see GET /v1/messaging/prices) · Rate limit: 60/min
