Practical tips with Spoki.*\n\n---\n\n**Customer** **communications** have moved to **messaging**: **customers** expect **fast** **replies**, **conversations** in one **thread**, and **support** or **sales** on the **channel** they use every day. The **WhatsApp** **Business** **API** lets **businesses** **scale** these **conversations** with **approved** **templates**, **automation**, and **compliance** with **WhatsApp** **policy**—so **relationships** improve and **teams** work from one **inbox**.\n\nThis guide covers **everything** you need to know about the **WhatsApp** **Business** **API** for **improved** **customer** **communications** and **relationship**: **what** the **API** is, **templates** and **sessions**, **use** **cases**, **compliance**, and how **platforms** like Spoki help you get started.
