Getting Started with Pinnacle

Pinnacle is the RCS API for developers. We make it easy to build, test, and scale RCS and SMS messaging - send your first message in minutes, not weeks.

What is RCS?

RCS (Rich Communication Services) upgrades traditional SMS with features like:

• Rich Media: High-resolution images, videos, and audio
• Interactive Elements: Buttons, carousels, and suggested replies
• Branding: Custom sender names and logos
• Read Receipts: Know when messages are delivered and read
• Typing Indicators: Real-time engagement signals

Why Pinnacle?

Getting RCS access typically takes 8-12 weeks with other providers. With Pinnacle, we get your RCS agent approved 2-3x faster by handling compliance on your behalf. Plus:

• Simple API: Send your first message with just a few lines of code
• Sandbox Testing: Test RCS messages before going live
• Flat Pricing: Carrier fees included, no surprises
• Real-time Conversations: View and manage messages in our dashboard

Getting Started

1. Get RCS Access and create your account
2. Grab your API key from the dashboard
3. Send your first message:

import { PinnacleClient } from "rcs-js";

const client = new PinnacleClient({ apiKey: your_api_key });

await client.messages.rcs.send({
  from: "your_agent",
  to: "+1234567890",
  text: "Hello from Pinnacle!",
});
