Complete Setup Guide
Follow each step carefully. Screenshots are included at every stage to guide you visually.
Create a Meta Developer Account
Go to developers.facebook.com and log in with your Facebook account. If this is your first time, you'll be asked to register as a developer — just follow the quick prompts.
Create a Meta App
From your Meta Developer dashboard, navigate to My Apps and click the green "Create App" button in the top-right corner.
When prompted to choose an app type, scroll down and select "Other", then choose "Business" as the app type. Give your app a name (e.g. "MyBusiness WA") and enter your contact email.
Add WhatsApp Product to Your App
After creating the app, open it from your apps list. You'll see the app dashboard. Look for the "Customize the Connect with customers through WhatsApp use case" and click on it to get started.
Start Using WhatsApp API
You'll be taken to the WhatsApp Business Platform overview. Click "Start using the API" button to enter the API setup. This is where you'll connect your business account and phone number.
Generate Your Access Token
In the API Setup page, you'll see an "Access Token" section at the top. Click "Generate access token" — this creates a temporary token you can use immediately. For production use, you'll need a permanent token (covered in the next step).
Copy Your Credentials
From the API Setup page, copy these three critical values. You'll need all three to configure Wagenius in the next step.

Configure Wagenius CRM
Now log into your Wagenius dashboard and navigate to your WhatsApp Account Settings. Paste the credentials you copied in the previous step.
After filling in all fields, click the orange "Submit" button to save your configuration.
Set Up Your Webhook
Webhooks allow Meta to send message notifications to Wagenius in real-time. Go back to Meta Developer Dashboard → your app → Configuration tab in the left sidebar.
