WhatsApp messaging API for businesses
MessageAPI connects your WhatsApp number to Tally, Busy, Google Sheets and your own software — so bills, reminders, campaigns and alerts go out from a dashboard or a simple HTTP API.
Features
One account for your dashboard, your integrations and your API.
Send text, files, or text with a file using plain GET or POST requests — from your own code, a browser, a spreadsheet or most ERP systems.
Send bills, vouchers, invoices, ledgers and reports straight to your customer's WhatsApp.
Sync Google Sheet data to set up messaging campaigns and triggers — even to numbers that aren't saved on your phone.
Free, unlimited Tally to WhatsApp TDL. Send bills, vouchers and reports, and automate payment reminders.
Extract contacts from your groups in a click, and send or schedule messages into any group.
Schedule WhatsApp messages and create task reminders for your employees or customers.
Keep track of employee chats and replies so important conversations don't get lost.
Print-to-WhatsApp for Windows: send bills from any desktop, ERP or POS instead of paper.

Both Android and iPhone. Link WhatsApp from your phone with a QR code or a pairing code, and open WhatsApp on the phone at least once every 14 days so the link stays active.

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.
