01 Overview

The official WhatsApp Business API is governed by rules that catch teams out: every template needs approval, a 24-hour service window restricts outbound messages, and opt-outs must be respected. We handle business verification and template approval, then connect the API to your application so order confirmations, delivery updates and payment reminders are triggered automatically. Replies land in your support inbox or a basic bot, and delivery status is stored against each message so you know what actually reached the customer.
