WhatsApp Business API

Official WhatsApp messages from your business number - straight from your software

Send receipts, payment reminders, alerts and PDF reports to your customers and staff on WhatsApp, automatically from our finance, billing and collection software - or from your own application through our API.

Official & verified

Uses Meta's official WhatsApp Business Platform (Cloud API). Messages come from your own business number with your business name - no risk of number bans from unofficial tools.

PDF documents

Attach PDF reports with the message - collection lists, cash book, statements, invoices - generated by your software and sent in one step.

Automatic alerts

Collection uploaded, data downloaded, cash book verified, payment received, due reminders - sent automatically when the action happens in the app.

Template messages

We help you create and get approval for message templates in English and Tamil, with your own variables (name, amount, date, line, etc.).

Delivery status

Every message is logged with sent, delivered, read or failed status, and failed messages are retried automatically.

Simple API

One HTTPS call with an API key sends a template message, with an optional PDF. Works from Android, VB.NET, ASP.NET or any language.

How it works

  1. Register - we set up your WhatsApp Business account and phone number with Meta (business verification documents needed).
  2. Templates - we create your message templates and submit them for approval.
  3. Connect - we switch on WhatsApp in your Venus Solutions software, or give you an API key for your own app.
  4. Send - messages go out automatically; you can see the history and status any time.
