WhatsApp Business API vs WhatsApp Business App: Which Do You Need?
They sound the same but solve very different problems. Here's a plain-English breakdown of when the free app is enough and when you need the official API.
The short answer
The WhatsApp Business app is a free mobile app for a single business phone, ideal for solopreneurs and very small shops. The WhatsApp Business API (now the WhatsApp Business Platform / Cloud API) is for teams that need to message at scale, give multiple agents access to one number, and automate sending.
If you have a team, send to more than a few hundred people, or want automation and analytics, you need the API — and a platform like Sandeshly to use it without writing code.
Broadcasting: 256 contacts vs thousands
The app's broadcast lists are capped at 256 contacts and only reach people who have saved your number. The API lets you send approved template messages to thousands of opted-in contacts, personalised per recipient, with throttling and retries handled for you.
Team access and the shared inbox
The app runs on one device — two staff can't answer the same number at once. With the API and a shared team inbox, your whole team handles one business number, with assignment, notes, and saved replies.
Automation, templates and analytics
Drip sequences, auto-replies, message templates, and delivery/read analytics don't exist in the free app. They're core to the API — and where most of the time savings come from.
What about the cost?
The app is free; the API has two cost layers — a platform subscription (Sandeshly starts at ₹999/month) and Meta's per-conversation message fees, which depend on category and country. We keep the platform side transparent and in INR.
