REST API, webhooks, and a free sandbox for RCS Business Messaging — from ₹0.12 a message.
MetaReach's RCS API is a REST interface for sending rich cards, carousels, and suggested replies programmatically from your own app or CRM, with webhook callbacks for delivery and read status. There's a free sandbox to test integration before going live, automatic SMS fallback when a device doesn't support RCS, and pricing from ₹0.12 per message with no charge for API access or documentation.
Put simply, the RCS API is a REST interface that lets your own application send Rich Communication Services messages — rich cards, image carousels, suggested replies, the works — without anyone touching a dashboard. Instead of logging in to send a campaign one batch at a time, you trigger the message from inside a workflow: an order confirmation the second a payment clears, a delivery update the moment a shipment status changes, or a personalised offer fired off by something a user just did on your site.
It sits inside MetaReach's RCS Messaging (see RCS overview) platform and is structured a lot like our SMS API and WhatsApp Business API — so if your team has already wired up either of those, adding RCS on top is a fairly small lift.
Your system sends an HTTP request to MetaReach's endpoint with the recipient's number, the message content, and whatever interactive elements you're including. From there, MetaReach checks whether that number can actually receive RCS — and if it can't, the message falls back to plain SMS automatically, no extra code required on your side. The message goes out over whichever carrier the recipient is on — Jio, Airtel, or Vi — and once it's delivered or read, a webhook fires back to your system so you know exactly where things stand.
Every request is authenticated with an API key issued when you sign up, passed as a header on every call you make:
Here's a basic rich-card send, stripped down to the essentials:
This is illustrative — the full request/response schema, error codes, and rate limits are in the complete API documentation, which you get access to after signing up for the sandbox.
Most teams end up hooking the RCS API into their CRM so messages fire directly off customer records — a rich-card appointment reminder the moment a lead's status changes, say, or a carousel of recommended products pulled from someone's purchase history. Delivery and read receipts sync straight back to the CRM through the webhook, so sales and support see message status without leaving the tool they already live in.
Set a webhook_url in your send request, or once in your account settings,
and MetaReach posts a JSON payload to that URL every time a message is delivered, read,
or fails — complete with a message ID, timestamp, and status code. That means your
system finds out the moment something changes, instead of asking the API repeatedly and
burning through quota for no reason.
| Tier | Volume | Price per Message |
|---|---|---|
| Starter | Up to 5,000/month | ₹0.20 |
| Business | 5,000 – 50,000/month | ₹0.15 |
| Enterprise | 100,000+/month | ₹0.12 |
API access and documentation don't cost anything on top of that, on any tier. If you're still weighing RCS against SMS or WhatsApp for a given use case, the RCS pricing & comparison guide walks through where each one makes sense.
It's a RESTful interface for sending RCS Business Messages — rich cards, carousels, suggested replies — straight from your own application, CRM, or backend, instead of a dashboard. It's built for developers and businesses wiring RCS into an automated workflow.
Yes. There's a free sandbox environment to test API calls, message formatting, and webhook delivery before anything goes live.
MetaReach posts a real-time webhook to a URL you configure whenever a message is delivered, read, or fails, so your system tracks status without repeatedly polling the API.
Pricing starts at ₹0.12 per message on the Enterprise tier (100,000+ messages a month), ₹0.15 on the Business tier (5,000-50,000 a month), and ₹0.20 on the Starter tier (up to 5,000 a month). API access and documentation are free on every tier.
