Overview
What is the WhatsApp Business API?
The WhatsApp Business API is the version of WhatsApp built for companies that need to message customers at scale. Unlike the free WhatsApp Business app, which a person uses by hand on a phone, the API is connected to software. Your systems send messages automatically, and incoming replies flow back to your team or to a chatbot.
Short answer: The WhatsApp Business API connects your own software to WhatsApp so you can send order updates, reminders, OTPs and campaigns automatically, and handle customer replies with agents or chatbots.
Who needs it
Any business that sends more messages than one person can type: online stores sending order updates, clinics confirming appointments, schools sharing notices, lenders sending payment reminders, and support teams that answer many customers at once.
What SMSNiti adds
We take care of the technical and approval work: registering your number, setting up your business profile, writing and submitting templates, and connecting the API to your tools. After launch you have a team to call when something needs fixing.
