Sync WhatsApp groups into your CRM

Overview

WhatsApp groups are the dark matter of WhatsApp Business. Most CRMs ignore them or shove every group message into a generic "unknown contact" pile. Wazzap models each group as a first-class conversation, keyed by the group ID, with the group avatar and name pulled straight from WhatsApp.

Every inbound and outbound message your number sends inside any group it belongs to appears in the CRM's Conversations tab. Agents see who said what (with the participant's number), can reply for the whole group, mention contacts, and trigger workflows the same way a 1-to-1 chat would.

How it works

1. Your Wazzap-connected number joins (or already belongs to) a WhatsApp group.
2. Wazzap detects the group automatically and surfaces it in your CRM as a new conversation.
3. Inbound group messages stream into the conversation as they arrive.
4. To send a message into the group, reply from the same composer and Wazzap routes it back.

Receiving group messages

No setup. Once your number is in the group, messages start landing in the CRM. Each message carries metadata you can use:

• Sender phone. The actual WhatsApp number of the person who wrote.
• Sender name. The display name they use in WhatsApp.
• Group ID. Used to address replies. Looks like 120363025xxxxxxxx@g.us.
• Group name + avatar. Pulled straight from WhatsApp.

Sending into groups

To send a message into a group from your CRM, target the group's ID instead of an individual phone number:

to: 120363025XXXXXXXX@g.us
body: Hey team, the weekly recap is live 👇

Through the HighLevel integration, replying from the conversation tab handles the addressing for you. Through the REST API, you supply the @g.us address as the recipient in your usual POST /messages call.

Where to find the group ID

The easiest way: open the group inside your CRM, look at the conversation header. Wazzap surfaces the ID there.

For programmatic discovery, hit:

curl https://api.wazzap.mx/v4/groups \
  -H "Authorization: Bearer $WAZZAP_KEY"

You get back a list of every group your number is in, each with its ID, name and participant count.

Beta limits

• Read receipts for individual participants don't sync. WhatsApp doesn't expose them per-user inside groups.
• Admin-only events (member added, removed, group renamed) sync as system messages, not as triggers.
• Polls inbound arrive as text descriptions, not as interactive widgets.
• Mentions with @ sync as plain text in inbound, but outbound mentions work natively.
• The group must have your number as a member. Wazzap can't read groups you aren't in.

Troubleshooting

Group messages don't appear in my CRM

Confirm your Wazzap number is actually a member of the group (open WhatsApp on your phone and verify). If it is, hard-refresh the CRM and look in the Conversations tab. The first message that arrives after the number joins is what triggers the conversation creation.

My outbound reply goes to the wrong place

Double-check the recipient ID ends with @g.us. A normal phone number ends with @s.whatsapp.net internally. The two address spaces are different, and a typo will silently send to a 1-to-1 thread instead of the group.

I'm rate-limited inside a busy group

Pace your outbound. WhatsApp throttles bots that flood groups even more aggressively than it throttles 1-to-1 spam. Add a 3 to 5 second delay between consecutive sends, or use the delay message command for scheduled drips.
