Before You Start

Make sure you have the following ready before connecting your WhatsApp Business number to Zappilo:

  • A WhatsApp Business number that you can access for verification.
  • Administrator access to your Zappilo workspace.
  • Your official business name, logo, and business description.
  • Access to the Meta Business account that owns the WhatsApp number, when applicable.

Connect Your WhatsApp Business Number

1. Open the WhatsApp setup area

Sign in to Zappilo, open your workspace settings, and choose the WhatsApp channel setup option. You must have workspace administrator permission to complete the connection.

2. Start the connection flow

Select the option to add a WhatsApp Business account. Follow the on-screen Meta connection flow and sign in with an account that can manage the required business assets.

3. Select or register the business number

Choose the WhatsApp Business account and phone number you want to use. If you are registering a new number, provide the requested business information and select the available verification method.

4. Complete verification

Enter the verification code delivered to the selected phone number. Keep the setup window open until Zappilo confirms that the account and number are connected.

5. Review the channel configuration

Confirm the display name, business profile, organization assignment, and team routing settings. Save the configuration before leaving the page.

6. Send a test message

Use the connected channel to send a test message to a permitted recipient, then reply to confirm that incoming and outgoing messages appear in the unified Zappilo chat page.

Recommended Practices

  • Use an official business number controlled by your organization.
  • Confirm the correct Meta business assets before completing the connection.
  • Review team routing and AI settings before opening the channel to customers.
  • Keep business profile information consistent with your website and Meta business details.

How Messages Flow in Zappilo

After the channel is connected, incoming WhatsApp messages appear in the shared chat workspace. Zappilo can associate the conversation with a contact, apply routing rules, use configured AI behavior, and run eligible automation while preserving the conversation for your team.

Troubleshooting

If the connection cannot be completed, verify that your user can manage the Meta business account, that the selected number is eligible for the connection flow, and that any previous provider migration has been completed. Review the error shown by Meta or Zappilo before retrying.

FAQs

Frequently Asked Questions

Can I connect multiple WhatsApp numbers?

Your ability to connect multiple numbers depends on your Zappilo plan and WhatsApp account configuration. Each connected number is managed as its own channel.

Will my previous WhatsApp message history be imported?

Previous message history is not automatically imported. New conversations are available in Zappilo after the channel connection is active.

What if the number is connected to another provider?

Complete the provider migration or disconnect the number through the supported Meta process before connecting it to Zappilo.

Why did verification fail?

Confirm that you can receive the verification code, that your Meta user has the required permissions, and that the selected business account owns the phone number.
