Quick guide to WhatsApp Business Calling API

WhatsApp Business Calling is a powerful tool for businesses to engage with customers through voice-over-IP (VoIP) calling within the WhatsApp app. This integration combines the convenience of WhatsApp with Twilio's VoIP and API capabilities, allowing businesses to handle both text and voice communications with customers in a single app. With this feature, companies can track all conversations in one place, use WhatsApp's familiarity to make interactions more personal for their customers, and establish trust through branded communications. The service is billed on a per-minute basis, offering global reach at a predictable pay-as-you-go rate. Businesses can leverage WhatsApp Business Calling for various purposes such as sales and consultations, customer support, order confirmations and updates, and lead generation and nurturing, making it an essential tool for customer engagement and growth.
