Chrome extension required

Send personalized WhatsApp messages from your own workflow.

The Arodos WhatsApp WebSuite SDK gives your app a small JavaScript interface for bulk messages, personalized templates, URLs, and files. It works together with the companion Chrome extension, which is the required browser dependency.

How to use it

A simple four-step setup

01

Install extension

Add the required Chrome extension from the install section before using the SDK.

02

Open WhatsApp Web

Sign in to WhatsApp Web in Chrome so your browser session is ready.

03

Initialize the SDK

Import the hosted SDK and initialize it with your access key.

04

Send messages

Pass contacts plus a template, and the SDK personalizes each message automatically.

What it supports

Built for practical messaging flows

The current SDK surface is intentionally compact: enough to cover common bulk messaging cases without making integration heavy.

Bulk text messages

Send one template across many contacts in a single call.

Template variables

Use placeholders like {name} for personalization, plus spin text like [Hi|Hello|Hey] for message variation.

URLs and files

Send links or supported file payloads with the same API style.

Paced processing

Messages are processed sequentially with built-in spacing between sends.

The “Safe” Sending Limits for WhatsApp Web

The limits depend entirely on whether the WhatsApp account is warm or old with a long history of chatting, or cold or new and just registered.

Account type	Daily recommended limit	Monthly target	Pricing
New / Unwarmed Account	10 – 50 messages/day	~200 - 1,000 messages	₹499
Mature / Warmed Account (1 year+ old)	100 – 150 messages/day	~2,000 – 3,000 messages	₹999
Highly Active / High Trust Account	200 – 300 messages/day	~5,000+ messages	₹2,999

Live tester

Test the sending flow from this page

Add up to three contacts with phone numbers and names, then use a template to test text, URL, or file sends without leaving the landing page.

For a real send, install the extension first and keep WhatsApp Web signed in. The sample SDK currently returns demo results until its WhatsApp bridge is connected.
