# Deploy Your First AI Agent to WhatsApp and Telegram with Photon Spectrum

> Photon's open-source Spectrum SDK lets devs deploy AI agents to iMessage, WhatsApp, Telegram and more with a single TypeScript codebase.

One of the most persistent friction points in building AI agents is distribution. You build something useful, then face the question: where do your users actually want to interact with it? The answer is almost never "a custom interface they have to download and learn." It's WhatsApp, Telegram, iMessage — the apps already open on their phones.

**Photon Spectrum** (MIT license, released April 22, 2026) solves this cleanly. It's an open-source TypeScript framework that routes agent logic to iMessage, WhatsApp, Telegram, Slack, Discord, Instagram, and phone — without users changing apps. Write your agent once; Spectrum handles the delivery.

This guide walks you through deploying a basic AI agent to WhatsApp and Telegram using Photon Spectrum.

## What Photon Spectrum Does

Spectrum sits between your agent logic and the messaging platforms. You define your agent's behavior in a single TypeScript codebase, add a providers array specifying which channels you want to reach, and Spectrum handles the platform-specific formatting, latency management, and delivery.

The architecture is edge-first, with sub-1-second delivery on Photon's network (compared to ~500ms–1.5s for typical CPaaS providers). Built-in audit logs, message histories, and human-in-the-loop controls are included — so you're not just routing messages, you're operating an observable agent system.

Key capabilities:
- **Adaptive content rendering** — message structure and interaction patterns adapt to each platform's native constraints
- **One-line channel addition** — adding a new platform is a single entry in the providers array
- **Scale-transparent** — same architecture handles early experimentation and high-volume production
- **MIT licensed** — no vendor lock-in, full source available

## Prerequisites

- Node.js 18+ and npm
- A [Photon account](https://app.photon.codes) (free tier available)
- WhatsApp Business API access (or a Telegram bot token for easier testing)
- TypeScript project setup (or use the Spectrum starter template)

## Step 1: Install Spectrum

```bash
npm install spectrum-ts
```

That's the entire install. No complex dependency chains.

## Step 2: Set Up Your Providers

Create a `spectrum.config.ts` in your project root:

```typescript
import { SpectrumConfig } from 'spectrum-ts';

export const config: SpectrumConfig = {
  apiKey: process.env.PHOTON_API_KEY,
  providers: [
    {
      type: 'whatsapp',
      phoneNumberId: process.env.WHATSAPP_PHONE_ID,
      accessToken: process.env.WHATSAPP_ACCESS_TOKEN,
    },
    {
      type: 'telegram',
      botToken: process.env.TELEGRAM_BOT_TOKEN,
    }
  ]
};
```

Each entry in `providers` activates a channel. To add iMessage later, you'd add a single `{ type: 'imessage', ... }` entry. No structural changes to your agent logic required.

## Step 3: Write Your Agent Handler

Create your main agent file:

```typescript
import { Spectrum, Message } from 'spectrum-ts';
import { config } from './spectrum.config';

const spectrum = new Spectrum(config);

spectrum.onMessage(async (message: Message) => {
  const userInput = message.text;
  
  // Your agent logic here — call your LLM, run tools, etc.
  const agentResponse = await runYourAgent(userInput);
  
  // Respond through whatever channel the message came from
  await message.reply(agentResponse);
});

spectrum.listen();
```

The `message.reply()` method automatically routes the response back through the correct platform. Your agent logic is completely platform-agnostic.

## Step 4: Sending Platform-Native Content

Spectrum adapts content to platform constraints automatically. But you can also use platform-specific features when you want them:

```typescript
// Send a poll via iMessage
const imessage = spectrum.channel('imessage');
await imessage.sendPoll({
  question: "Where should we eat?",
  options: ["Sushi", "Hotpot", "Italian"]
});

// Send a message to a specific WhatsApp number
const whatsapp = spectrum.channel('whatsapp');
await whatsapp.send({
  to: '+15551234567',
  text: 'Your order has been processed!',
});
```

## Step 5: Deploy and Monitor

Spectrum includes built-in observability. In the Photon dashboard, you'll see:
- **Message logs** with full conversation history per user per channel
- **Delivery latency** per platform
- **Error rates** and retry status
- **Human-in-the-loop controls** to pause or intervene in agent conversations

For production deployment, set your environment variables securely and run:

```bash
npm run start
# or with PM2 for process management:
pm2 start dist/index.js --name "my-spectrum-agent"
```

## Real-World Considerations

**WhatsApp Business API access** has a more involved approval process than Telegram. If you want to test quickly, start with a Telegram bot (takes 5 minutes via @BotFather) and add WhatsApp once your agent logic is working.

**Rate limits vary by platform.** Telegram is permissive for bots; WhatsApp Business API has per-user conversation windows and message templates for outbound-first messaging. Spectrum doesn't abstract these away entirely — you'll need to understand the constraints of each platform you deploy to.

**OpenClaw users:** If you're running OpenClaw agents, Spectrum is a clean complement. Your OpenClaw agent can handle reasoning and tool orchestration; Spectrum handles multi-channel delivery to wherever your users are. The two can be combined by calling your OpenClaw agent logic from inside the `spectrum.onMessage()` handler.

## Why This Matters

Most agent distribution strategies either require users to adopt new interfaces or lock developers into a single platform's SDK. Spectrum cuts through that: write once, deploy everywhere users already are. The MIT license means you own your deployment and aren't dependent on Photon remaining a viable business.

For the broader agentic AI ecosystem, tools like Spectrum are what enable agents to operate where human attention actually lives — not where developers find it convenient to put them.
