WhatsApp

There are three ways to put your AI agent on WhatsApp. Pick whichever fits your business — the agent behaves identically on all of them.

Official Meta API QR Connect (built-in) QR Connect (WaSender)
Setup Meta Business verification required Scan a QR code with your phone Scan a QR code with your phone
Number type WhatsApp Business API number Any regular WhatsApp number Any regular WhatsApp number
Time to go live Depends on Meta approval Under 2 minutes Under 2 minutes
External account needed? Meta Business account No — fully in-app Yes — a free WaSender account
Best for Established brands Getting started fast, simplest option If you already use WaSender

Option 1 — Official Meta WhatsApp Business

  1. Go to Business Profiles → Connect WhatsApp.
  2. Log in with Meta and complete the embedded signup (business name, number verification).
  3. Done — webhooks are configured automatically.

Option 2 — Built-in QR Connect (no external account)

  1. Go to Business Profiles → Connect WhatsApp → Connect via NextCore Evolution API.
  2. Scan the QR code shown with the WhatsApp you want to automate.
  3. Done — no third-party website, no separate account, no webhook/API key to copy. This is the fastest way to get started.

Option 3 — QR connect via WaSender

  1. Create a session at wasenderapi.com and scan the QR with the WhatsApp you want to automate.
  2. In WaSender's dashboard, open your session's Webhook settings:
  3. Set the Webhook URL shown on your Sales Chat AI Business Profile page (it looks like https://scai.nextcorebd.com/webhook/wasender/<your-id>/).
  4. Enable the messages events (tick messages.received — if you also see messages.upsert, tick both).
  5. Copy the Webhook Secret from WaSender's Credentials tab and paste it into your Business Profile in Sales Chat AI.
  6. Paste your WaSender API key as well, and save.

The full walkthrough with screenshots is in the WaSender connect guide.

What works on WhatsApp

Everything on all three connection types: instant replies, typing indicator and blue-tick seen marks, image and voice-note understanding, sending product photos and audio files, quoted-reply awareness, order taking, returning-customer memory, and auto-pause when you reply manually from your phone.

Note: group chats are ignored by design — the agent only answers direct customer messages.
