What happens behind each message

  1. 01

    The trigger listens on your number

    Each bot starts from a Trigger block where you pick the WhatsApp Business number it answers on.

  2. 02

    AI Studio writes the answer

    Replies come from the knowledge base you trained, so the bot answers with your policies and product details.

  3. 03

    Human handover passes the chat on

    The conversation goes to the team you choose, with set messages for when no agent is free or it is outside operating hours.

  4. 04

    Your team picks up with context

    With auto-assign on, the chat goes straight to an agent. Otherwise it waits in the Unassigned tab, and every user gets a browser notification.

What the WhatsApp chatbot can do

AI answers, no-code flows and the template tools Meta requires for proactive messages, in one workspace.

Train it on what you already have

Add your website, documents or pasted text. AI Studio uses these sources to write its WhatsApp replies.

  1. Domain or sitemap import

    Enter a domain or sitemap address and ReplyCX imports its URLs, or list specific pages.

  2. Files up to 5 MB

    CSV, XLSX, TXT, PDF, DOC and DOCX.

  3. Text snippets

    Paste up to 2,500 characters straight into the knowledge base.

  1. WhatsApp Flows

    Open structured, multi-screen forms built in Meta's WhatsApp Flow builder inside the chat.

  2. Product catalog

    Customers browse products, pick items and add them to a cart without leaving WhatsApp.

  3. Send Template block

    Send approved rich templates, including carousels, in the middle of a live bot conversation.

Template and campaign tools

  1. 01

    Template manager

    Create templates, submit them for Meta's approval and track whether each one is accepted or rejected.

  2. 02

    Template sync

    Moving from another platform? Import your existing Meta templates with the Sync button.

  3. 03

    Carousel templates

    Swipeable templates with 2 to 10 cards and up to 2 buttons on each card.

  4. 04

    Outbound campaigns

  5. 05

    Marketing Messages Lite API

    Outbound bots support Meta's MM Lite API for marketing messages.

  6. 06

    One inbox across channels

    WhatsApp sits beside web chat, SMS and email, and context carries over when a customer switches channel.

Set up a WhatsApp chatbot in four steps

The bot runs on a WhatsApp Business API number. Connect your own Meta number, or test first with a 360Dialog sandbox number.

  1. 01Verify your Meta Business Manager
  2. 02Add your number to a Meta app
  3. 03Connect the number in ReplyCX
  4. 04Pick it in the bot trigger and deploy

Before you start

  1. A verified Business Manager

    Meta needs your business to be verified by Facebook.

  2. A number not on the WhatsApp app

    The number cannot have an active WhatsApp account linked to it.

  3. A permanent access token

    Generated for a system user in Meta Business settings, with WhatsApp management and messaging permissions.

  4. Templates for proactive messages

    Messages you start, such as reminders, use templates Meta has approved.

What it costs

  1. ReplyCX plan

    Plans start at $79 a month, priced by conversation volume, and every plan starts with a 14-day free trial.

  2. AI answers

    AI Studio and custom knowledge base training are on the Pro and Enterprise plans.

  3. Human handover

    Live chat handoff starts on the Growth plan.

  4. Meta's fees
