Business Messaging

Business messaging for WhatsApp and SMS

2Chat is a business messaging platform that connects your WhatsApp and SMS numbers to one shared inbox, one REST API and one set of webhooks. Your team replies from the inbox, and your systems send and receive through the API.

How it works

How business messaging works in 2Chat

Every message goes through the same layers: a connected channel, the shared inbox and the API. What changes per channel is how you connect it and the rules it follows.

  1. 01

    Connect your messaging channels

    Link WhatsApp numbers by QR code or through the WhatsApp Business API, and add SMS-enabled virtual numbers.

  2. 02

    Answer from one shared inbox

    Incoming messages from every connected number land in the 2Chat Live Chat, where agents reply and see the full history.

  3. 03

    Send in bulk or on a schedule

    Send personalized campaigns from a CSV list, schedule messages for later, and let no-code flows reply automatically.

  4. 04

    Connect your systems through the API

    Send and read messages with one API key, and receive events from every channel through webhooks.
