Six businesses that needed WhatsApp connected to their existing systems.
Arjun runs a Shopify store. His customers get email order confirmations — but nobody reads email. He wants WhatsApp order updates: confirmation, shipped, delivered. His dev can write code but needs a simple API to call.
One API call per event. Order confirmation on WhatsApp in under 5 seconds.
Priya's healthcare SaaS sends appointment reminders via SMS. Open rates are 20%. She needs WhatsApp delivery — but can't manually send 500 reminders daily. Her system needs to trigger messages automatically when appointments are booked.
Her system calls the API. 500 reminders go out. 95% open rate on WhatsApp.
Vikram's D2C brand sends 10,000 broadcast messages weekly. But he has no idea how many are actually read. His marketing team needs delivery and read receipts in their analytics dashboard — not locked inside a WhatsApp platform.
Webhooks push delivery + read events to his dashboard in real-time.
Ritu's FinTech app processes 2,000 UPI payments daily. Customers call support asking "Did my payment go through?" She wants instant WhatsApp receipts — amount, merchant, balance — triggered the second the payment clears.
Payment processed → API call → WhatsApp receipt in 3 seconds. Zero support calls.
Sanjay's coaching institute has an LMS (learning management system). When a student enrolls, the admin manually sends a WhatsApp welcome message with login credentials. With 200 new students per batch, this takes hours.
Student enrolls in LMS → API sends login details on WhatsApp automatically.
Meera's real estate agency gets 50 leads daily from website forms. She enters them in her CRM, then manually WhatsApps property brochures. By the time she sends the brochure, the lead has already called 3 other agents.
Form submitted → CRM saves lead → API sends brochure on WhatsApp in 10 seconds.
Two Tools. One Dashboard.

Open Settings
Open your Chat Mitra dashboard and go to Settings. You'll see a tab called 'API Key' — click on it.

Get Instant Alerts in Your App
When a customer replies on WhatsApp, or when your message gets delivered or read — Chat Mitra instantly tells your app. Your CRM gets updated, your dashboard shows real-time stats, your team gets notified. All automatic.
Three alert types. Toggle on what you need. Test button for each. Your developer sets it up in minutes.
Create Webhook
In your Chat Mitra dashboard, go to Settings and click the 'Webhooks' tab. Then click 'Create Webhook'.
Webhooks are like instant alerts. When something happens on WhatsApp (customer messages you, message gets delivered), Chat Mitra sends a notification to your app.
Developer Configuration
Paste URL
Paste the URL where your app will receive these alerts. Your developer will give you this link.
This is where Chat Mitra sends notifications. Once set, it can't be changed — if your developer gives you a new URL later, just delete and recreate.
Endpoint
https://your-app.com/webhooks/chatmitraCopy Secret
A secret key appears on screen — copy it right away and send it to your developer. It's shown only once!
This secret key is like a password. Your developer uses it to verify that alerts are actually coming from Chat Mitra, not from someone pretending to be Chat Mitra.
Webhook Secret
whsec_7f3a9b2e1d... Pick Events
Choose which alerts you want. Turn on 'Customer Replied', 'Message Sent', or 'Delivery Status Changed' — or all three.
Pick only what you need. Want to know when customers reply? Turn on 'Customer Replied'. Want delivery reports? Turn on 'Delivery Status'.
Subscribe to Events

Always test before going live. The test button sends a fake notification to your app — so your developer can make sure everything is connected properly.

Frequently Asked Questions
How do I get my Chat Mitra API key?
Log into your Chat Mitra dashboard, go to Settings, and click the API Key tab. Your key is auto-generated when you create a project. Click 'Copy Key' to copy it. Use it as a Bearer token in the Authorization header of your API calls. If your key is compromised, click Regenerate to instantly create a new one and invalidate the old one.
What API endpoint do I use to send WhatsApp messages?
The endpoint is POST https://api.chatmitra.com/v2/client/send_template. You send the template name, language code, recipient phone number (with country code, no + sign), and any dynamic parameters. The response includes a messageId and creditsUsed. Full request and response examples are available in the built-in API Documentation inside your dashboard.
What webhook events does Chat Mitra support?
Chat Mitra supports three webhook events: message.received fires when a customer sends you a message, message.sent fires when a message is sent to a customer, and message.status.updated fires when delivery status changes (sent, delivered, read, failed). You can toggle each event on or off independently and test each with a sample payload.
How do I verify webhook payloads are from Chat Mitra?
When you create a webhook, Chat Mitra generates a signing secret shown once at creation. Every webhook payload includes an HMAC signature. On your server, compute the HMAC of the payload body using your secret and compare it to the signature in the request header. If they match, the payload is authentic.
How much does the API and webhook feature cost?
API access and webhooks are included in the Chat Mitra Pro plan at ₹999 per month. Both Starter and Pro plans charge ₹0.20 per conversation plus Meta API charges. There are no extra fees for API calls or webhook deliveries. You get a 15-day free trial to test everything before paying.
Can I change my webhook URL after creating it?
No. The webhook URL is locked after creation for security reasons. If you need to change the URL, delete the existing webhook and create a new one with the new URL. A new signing secret will be generated. Update your server to use the new secret.
What programming languages are supported?
Chat Mitra provides ready-to-copy code examples in 5 languages: cURL, JavaScript (Node.js), Python, PHP, and Axios. The API is a standard REST endpoint that works with any language or tool that can make HTTP requests. You can also use it with no-code tools like Zapier, Make, or n8n by configuring the HTTP request module.
Is the Chat Mitra API the same as the WhatsApp Cloud API?
Chat Mitra's API wraps the official WhatsApp Cloud API. You don't need a separate Meta developer account or direct Cloud API access. Chat Mitra handles the Meta connection, template approval, phone number verification, and compliance. You use one simple endpoint with your Chat Mitra API key instead of dealing with Meta's token management and graph API directly.
What happens if my webhook endpoint is down?
If your endpoint returns a non-200 status or times out, Chat Mitra marks the delivery as failed. You can check webhook status in the dashboard — it shows Connected or Disconnected. We recommend monitoring your endpoint and implementing retry logic on your server for critical event processing.
Is Chat Mitra cheaper than Wati or Interakt for API access?
Chat Mitra Pro costs ₹999 per month with ₹0.20 per conversation. Wati starts at $59 per month (approximately ₹5,000) with additional per-message markup. Interakt's Growth plan starts at ₹2,499 per month with 12 to 39 percent markup on conversations. AiSensy starts at ₹1,500 per month. Chat Mitra includes API access, webhooks, auto reply, and unlimited team members in the Pro plan.
