Connect WhatsApp in one click

No developer console required. Just log in with Meta and your number is configured automatically — like magic.

Your email

Used as your account identifier. Your API key will be tied to this email.

Step 2 of 4 · Meta Developer Console

Find your Phone Number ID

Your Phone Number ID and WhatsApp Business Account (WABA) ID are in the Meta Developer Console — not in WhatsApp itself.

developers.facebook.com → Your App → WhatsApp → API Setup

App Name My Business App

WhatsApp Business Account 2858436544498712 WABA ID ← copy this

This is your WhatsApp Business Account ID — a long number

Phone Number ID 970776842795623 Phone ID ← copy this

NOT the same as your phone number — it's a numeric ID

Phone Number +44 20 7946 0123

📍 Where to find it: Go to developers.facebook.com → select your app → WhatsApp in left sidebar → API Setup. Both IDs are shown at the top.

Phone Number ID

A long numeric ID — looks like 970776842795623. Not your actual phone number.

WhatsApp Business Account (WABA) ID

Also a long numeric ID, found just above Phone Number ID in the console.

Step 3 of 4 · Access Token

Generate your access token

Choose how you'll authenticate. If you're just testing, grab a quick 24-hour token. For production, create a permanent System User token.

1In the Meta Developer Console, go to WhatsApp→API Setup
2Under Step 1: Add phone number, click Generate access token
3A temporary token appears — copy it and paste it below. It expires in 24 hours.

⏱ This token expires after 24 hours. Use it for testing, then upgrade to a permanent token when you're ready for production.

1Go to Meta Business Settings→Users→System Users
2Click Add, give it a name (e.g. WhatAgent Bot), set role to Admin
3Click Generate new token on that system user
4Select your WhatsApp app from the dropdown
5Grant these scopes:
whatsapp_business_messaging whatsapp_business_management
6Copy the generated token — this one never expires.

✅ Recommended for production. System user tokens don't expire and aren't tied to a personal Facebook account.

Access Token

Starts with EAA. Paste the full token, including the prefix.

Step 4 of 4 · Connect to WhatAgent

Connect your number

First, get a WhatAgent API key — then we'll wire everything together in one click.
