Get started with WhatsApp
Review phone numbers, templates, account limits, and costs before automating WhatsApp messages.
Choose the connection method before changing a number
Review the onboarding route available in your Bual Pro account before changing an existing WhatsApp number's registration.
Meta supports Coexistence for eligible WhatsApp Business app onboarding. With that setup, an existing Business app number can also use Cloud API. Availability depends on the provider's onboarding implementation and Meta's requirements; confirm whether Bual Pro offers that route for your account before proceeding. See Meta's Business app onboarding guide.
Do not delete a Business app account based on the assumption that app and API use can never coexist.
For developer testing, follow Meta's getting-started guide. Use the testing resources offered in that setup before planning a production launch.
Check verification and messaging limits
Complete the verification tasks Meta shows for your business and review your account's current messaging limit in WhatsApp Manager before planning business-initiated messages.
Use the messaging-limit guide to check your portfolio's allowance and scaling options. Refer to Meta's current messaging-limit documentation for the applicable requirements.
Use templates and respect the service window
To initiate a WhatsApp conversation, use an approved template for its intended purpose. The recipient must have provided their number and opted in to receive messages from your business.
You can reply without a template while the 24-hour customer service window is open. The window opens or resets when the user messages your business. Outside it, use an approved template. See the WhatsApp Business Messaging Policy.
Sync approved templates in Bual Pro
After Meta approves a template, open Settings, then Channels, then WhatsApp in Bual Pro and sync the WhatsApp templates again.
You can then send a template from the Inbox.
Check costs and billing
Meta moved to per-message pricing on 1 July 2025. Charges depend on the delivered message's category and recipient market, with applicable free tiers and other conditions. Review Meta's current pricing and rate cards before estimating costs; do not assume a 24-hour conversation carries one fixed charge or that every service message is free.
Check Bual Pro's current pricing for subscription features and any Bual Pro fees. Follow the billing setup shown for your WhatsApp account in Meta Business Suite and review the messaging and billing information available for your account.
Review data handling and display names
For Cloud API data handling, read Meta's Data privacy and security documentation.
Follow Meta's display-name guidance when naming your business number. Use the current account status shown by Meta when checking business recognition and display behavior.
