Required

Official Business Account (OBA) Required

To use WhatsApp Groups API, your business phone number must have Official Business Account (OBA) status — a blue checkmark granted by Meta to authentic, notable brands. OBA requires Meta business verification, at least 30 days on the platform, an approved display name, and two-step verification.

Pricing

Transparent, Pay-as-You-Go Pricing

WhatsApp Groups use per-message pricing — you only pay for what gets delivered.

Marketing messages

Charged per delivered message, per recipient. If you send a template to a group of 5 and all 5 receive it, you pay for 5 messages.

Utility & service messages

Free when sent inside a customer service window — when any participant has messaged you first within 24 hours.

No extra fees

The Groups API is included with your AssistantLabs plan. WhatsApp message rates are passed through at cost.

Ask us on WhatsApp
Who can use WhatsApp Groups?
Any business with an Official Business Account (OBA) on the WhatsApp Business Platform. OBA requires Meta business verification, 30+ days on the platform, an approved display name, and two-step verification.
How do participants join a group?
You send them an invite link via a WhatsApp template message. Participants tap the link and choose whether to join. You cannot add people to a group automatically.
What message types are supported?
Text messages, images and media, and approved WhatsApp message templates. Voice/video calls, disappearing messages, view-once media, and interactive buttons are not supported.
How does pricing work?
You pay per message delivered to each group participant. If a participant messages you first, a customer service window opens and utility/service messages are free for 24 hours. Marketing templates are always charged.
What happens when I delete a group?
All members lose access immediately and no further messages can be sent to that group.
Is WhatsApp Groups available in all countries?
Yes — available in all countries where WhatsApp Cloud API is supported.
Can participants reply in the group?
Yes. Any participant can reply in the group chat and other members will see it. Replies also come into your AssistantLabs inbox so your team or AI agent can respond.
Can I send the same message to multiple groups at once?
Yes. Through AssistantLabs you can broadcast a template message to multiple groups in one action — no need to send them one by one.
Can I create groups automatically from my CRM or contact list?
Yes. AssistantLabs lets you trigger group creation and invite sending automatically based on CRM data, purchase events, or any workflow you set up.
What happens if someone leaves a group?
They lose access and stop receiving messages. You can send them a new invite if you want to re-add them.
