Twilio's WhatsApp API now supports typing indicators in its public beta, allowing developers to show users visual feedback while awaiting a response, thereby mimicking human conversation patterns and reducing perceived wait times. This feature is particularly useful for AI chatbots, order status lookups, and customer support workflows where backend processing may cause noticeable delays. The typing indicator appears when a response is being prepared and disappears either after 25 seconds or when the actual response is sent. The beta version is not covered by Twilio's SLA and is not compliant with HIPAA or PCI, making it unsuitable for healthcare or payment workflows. As part of a broader trend toward more conversational business messaging, the WhatsApp Business Platform continues to evolve, with recent additions like voice and video calling, emphasizing the importance of planning for richer, multi-modal customer interactions. Developers using Courier alongside Twilio can integrate typing indicators into their workflows to manage message timing efficiently, enhancing user experience by coordinating the indicator with processing delays.
