Frequently asked questions

What is the difference between WhatsApp Business and WhatsApp Business API?

The WhatsApp Business app handles business conversations through an app. The API can connect to platforms such as SaleSmartly for team workflows and integrations. Members, capacity, features and charges depend on the account and plan; API access does not automatically grant a verification badge.

How can we message customers who have not chatted with us before?

Use a Meta-approved template message, and make sure the customer has opted in to receive messages from your business. Outside the 24-hour conversation window, only template messages can be sent.

Who helps with the API number registration process?

The SaleSmartly support team can guide you through the connection requirements, business account setup and template submission. Use the help center or contact details on this page to discuss your existing number and setup.

Is it free to start?

You can start with the free plan. Check the pricing page for current user, channel and AI allowances. WhatsApp API usage may incur separate Meta charges.
