Official WhatsApp Business API
Give your team one place to handle every WhatsApp chat — with assignment, collision detection and AI assist, all on a single business number.
A shared WhatsApp inbox lets multiple agents handle conversations from one business number at the same time — instead of a single phone being passed around or chats trapped on one person's device. Connected to the official WhatsApp Business API, it gives every team member their own login while customers still see one consistent business identity.
Defuser's shared inbox adds assignment, internal notes, collision detection and Talksy AI assist — so your team collaborates on conversations without stepping on each other, and routine questions get answered automatically.
Get your whole team on WhatsApp in three steps.
Invite agents and give each their own seat on a single shared business number — no shared passwords or phones.
Route chats to the right agent, leave private notes, and see who's typing so no one double-replies.
Talksy handles routine messages 24/7 and escalates the rest to a human with full context.
Many agents work one number simultaneously, each with their own login and permissions.
Assign conversations to the right person or team and track ownership end to end.
See when a teammate is already replying so customers never get two answers.
Add private notes and @mentions to a chat without the customer ever seeing them.
Talksy drafts replies and handles routine chats so agents focus on what matters.
Handle WhatsApp, Instagram, Messenger and TikTok in the same shared view.
A shared inbox is the foundation; Defuser builds the rest on top. Add contact profiles and pipeline tracking with the WhatsApp CRM, bring every channel together in the unified inbox, and let automation and Talksy absorb routine volume — so your team scales support without scaling headcount.
Yes. Defuser's shared inbox lets your whole team work the same business number at once, each with their own login — something the free WhatsApp app, which allows only one active session, can't do.
Collision detection shows when a teammate is already viewing or replying to a conversation, and assignment gives each chat a clear owner — so customers never receive duplicate or conflicting answers.
Yes. Agents can add private notes and @mention teammates inside any conversation. These are visible only to your team, never to the customer.
It does. Defuser's inbox is unified, so WhatsApp, Instagram, Messenger and TikTok conversations all appear in the same shared view your team works from.
Yes. Talksy can draft replies, answer routine questions automatically 24/7, and escalate anything complex to a human agent with full context — so your team handles more without burning out.
