Connect WhatsApp Business
Start with your business phone number. Meta then asks you to approve access, so Vendor Sales Engine can work with your business messages once messaging is safely activated.
1Your business number
Enter the WhatsApp number your business owns. This does not connect your account or read any messages.
No number saved yet.
2Approve the connection with Meta
Meta confirms the business and the number. Eligible businesses may keep their existing WhatsApp Business app through Meta's supported coexistence flow.
Waiting for the required Meta app setup.
Meta Embedded Signup needs an approved Meta app and a secure HTTPS domain, so this local Windows test portal cannot complete production authorization. Never share WhatsApp verification codes, two-step PINs or access tokens with support.
3Connection and follow-up readiness
Follow-up scheduling is separate from live sending, which stays off until Meta phone registration, inbound webhooks, consent rules, template eligibility and messaging readiness are verified.
WhatsApp API usage charges, where they apply, are separate from your Vendor Sales Engine membership. This screen does not enable live messaging.
