WhatsApp messaging API for Indian businesses
Reach your customers with bills, payment reminders, OTPs, invoices and campaigns.
MessageAPI links your WhatsApp number to Tally, Busy, Google Sheets and your own software — so bills, reminders, campaigns and alerts go out from a dashboard or one simple HTTP call.

How it works
Here is what the MessageAPI dashboard looks like from the first QR scan to the delivery report.
Create your account — every new account gets a 3-day free trial. Add a device, give it a name and link WhatsApp by scanning a QR code or typing an 8-character pairing code.
Write your message, attach a bill or PDF, and pick recipients — type numbers, or use the numbers in a Google Sheet, even ones not saved on your phone.
Send now or schedule it — from the dashboard, from Tally or Busy, from Google Sheets, from Mobill Printer, or with one HTTP call to the API.
Every message sent from the API and the dashboard is recorded in your delivery report, so you can see what went out and when.

Yes. You can send text, files, or text with a file using simple GET or POST requests to https://messagesapi.co.in/chat/… with your user ID and device name. Your credentials and the full API reference are in your dashboard after you log in.
Yes. Send files from the dashboard, from Tally with the free TDL, from any Windows program with Mobill Printer, or through the API by passing a public file URL.
In any business, a large database of leads builds up over time, usually kept in Google Sheets or Excel. You can now send WhatsApp messages to any mobile number in a Google Sheet — not only the numbers in your phone book. A bigger database means more responses to your campaigns, and ultimately more sales for your business.
Use a Google Sheet as a calling database for your calling team and have them send WhatsApp messages to leads based on the response received. Create a new campaign and send it to selected or all mobile numbers in a sheet. Auto-send a WhatsApp message when a customer submits a Google Form. Create a task reminder list for employees or customers and schedule WhatsApp reminders from the sheet.
Today every WhatsApp account has multiple groups for networking, exchanging information and even as an MIS tool in business. Managing chats across these groups can be a big task, and important chats can get overlooked as new chats pile on top of older ones. WhatsApp Group Manager (WGM) solves this. Groups are also a source of free database for promoting your own business, but copying member data manually is time-consuming — with WGM it takes a click.
If you are an existing customer and want to use the new features, you need to buy a new plan. The wallet balance remaining in your existing plan will be adjusted by extending your plan validity.
Yes. Existing users can request a trial of the new services with their existing plan — follow the instructions on your homepage after logging in. All new users get a free 3-day trial by default.
All new features are available to existing users on the unlimited WhatsApp wallet plan only. Users on credit plans will not be able to use the new features.
You need a valid wallet plan to allocate new feature-based plans to your users. You cannot buy or transfer new plans with only credits in your account, but you can get your wallet recharged by surrendering your credits. For details, please call 9319916790.
