Connect a WhatsApp Business number

Use Meta Embedded Signup

Open Settings, WhatsApp accounts, then choose Connect with Meta. Sign in to Meta, select the correct business portfolio, WhatsApp Business Account and phone number, and approve the requested permissions. Chattill then registers the selected number inside your current tenant.

Number and Meta prerequisites

• You can sign in to the Meta account that manages the business.
• The business can create or select a WhatsApp Business Account.
• You can receive the verification method required for the phone number.
• The display name and business information comply with Meta policies.
• You understand whether the number must be migrated from another WhatsApp setup.

Test the connection

1. Send “Hello” to the business from a separate customer phone.
2. Confirm the inbound message appears in Chattill under the correct connected account.
3. Reply from Inbox while the customer-service window is open.
4. Confirm sent, delivered and read status updates when Meta provides them.
5. If you use more than one number, verify which account is marked as default.

Customer-service window and templates

WhatsApp allows free-form replies during the customer-service window opened by a customer message. Business-initiated outreach outside that window generally requires an approved WhatsApp template. Template eligibility, categories, quality and fees are controlled by Meta.
