WhatsApp preparation
Open Channels and choose the WhatsApp connection action. Use a business account and number you are authorized to manage. Follow the official sign-in and permission steps, select the eligible account and complete number verification when requested. Existing Business app coexistence depends on account and number eligibility; a connected status alone does not prove every feature is available.
Website Chat setup
In Channels, open Website Chat setup. Add the exact HTTPS website addresses you control to the allowed website list and copy the provided widget installation code into that website. Use the displayed public installation values; never place a private server credential in a page. Test from the allowed address, complete the visitor security check and send a synthetic message.
Check the complete journey
Confirm the message appears in Customer Workspace and test human handover. Check supported media and usage allowances before enabling automatic replies. WhatsApp reply windows and template requirements still apply; provider messaging charges are separate. If authorization fails, check account access and eligibility before repeating setup.
