WhatsApp Cloud API

Connect Whatsapp Number

This guide explains the general process for connecting your WhatsApp Cloud API number with Wemblo.

Step 1: Open WhatsApp settings in Wemblo

Log in to Wemblo and go to:

Settings → WhatsApp Channel

The exact menu name may depend on your account permissions.

Step 2: Add your WhatsApp account details

Enter the required values:

  • WhatsApp Business Account ID
  • Phone Number ID
  • Registered phone number
  • Business ID, if required
  • Access token

Save the settings after entering the details.

Step 3: Copy the webhook callback URL

Wemblo will provide a webhook callback URL.

Copy this URL because you will need to add it inside your Meta Developer app.

Step 4: Create a verify token

Create a secure verify token or copy the token generated by Wemblo.

The verify token in Meta and Wemblo must be exactly the same.

Step 5: Configure webhook in Meta

In your Meta Developer app:

  1. Open WhatsApp product settings.
  2. Go to webhook configuration.
  3. Paste the Wemblo callback URL.
  4. Enter the verify token.
  5. Verify and save.
  6. Subscribe to required WhatsApp events.

Step 6: Test inbound message

Send a WhatsApp message from another number to your connected business number.

Check if the message appears in Wemblo team inbox.

Step 7: Test outbound reply

Reply from Wemblo.

Confirm that the customer receives the message on WhatsApp.

Step 8: Test template message

If you want to start a conversation or send a follow-up outside the active customer service window, test an approved template message.
