# 07 - API Collection

## 07.1 Overview

This collection gives a runnable cURL for every OpenWA REST endpoint. The examples assume two environment variables — set them once and reuse them:

```bash
export BASE=http://localhost:2785
export API_KEY=owa_k1_your-api-key-here
```

(For the metrics endpoint also `export METRICS_TOKEN=...`.)

### Authentication

Every request carries the key in the `X-API-Key` header — REST auth is **header-only**, an `?apiKey=` query value is not accepted. Routes that mutate state need an `operator` key; API-key and settings management need an `admin` key; read-only routes accept any valid key. The metrics endpoint uses `Authorization: Bearer $METRICS_TOKEN` instead.

```bash
# the auth header that prefixes nearly every call below
-H "X-API-Key: $API_KEY"
```

### Responses

Responses are the **raw payload** — no `{ success, data }` envelope. A resource route returns the object directly; a list route returns a bare JSON array. Errors return the NestJS default shape `{ "statusCode", "message", "error" }`. Add `Content-Type: application/json` only when sending a body.

### Sections

Sessions · Messages · Webhooks · Groups · Contacts · Chats · Labels · Channels · Catalog · Templates · Plugins · Settings · Auth (API Keys) · Health · Infrastructure · Stats · Metrics · Events (WebSocket).

## 07.2 Endpoints

All examples assume `BASE` and `API_KEY` are exported (see 07.1). Paths are prefixed with `/api`.

### 07.14 Real-time (WebSocket)

Events are delivered over **Socket.IO** on the `/events` namespace (not a raw WebSocket). Use the `socket.io-client` package. Set `BASE_WS` (e.g. `ws://localhost:2785`) and `API_KEY`.

```bash
npm install socket.io-client
```

```js
// realtime.mjs — run: BASE_WS=ws://localhost:2785 API_KEY=... SESSION_ID=main node realtime.mjs
import { io } from 'socket.io-client';

const BASE_WS = process.env.BASE_WS || 'ws://localhost:2785';
const API_KEY = process.env.API_KEY;
const SESSION_ID = process.env.SESSION_ID || 'main';

const socket = io(`${BASE_WS}/events`, {
  auth: { apiKey: API_KEY }, // or transport.headers / ?apiKey=
});

socket.on('connect', () => {
  console.log('connected:', socket.id);
  socket.emit('message', {
    type: 'subscribe',
    sessionId: SESSION_ID,
    events: ['*'], // or e.g. ['message.received', 'session.status']
    requestId: 'sub-1',
  });
});

socket.on('message', (msg) => {
  if (msg.type === 'event') {
    console.log(`[${msg.payload.event}] ${msg.payload.sessionId}`, msg.payload.data);
  } else {
    console.log(`[${msg.type}]`, msg); // subscribed | unsubscribed | pong | error
  }
});

socket.on('connect_error', (err) => console.error('connect_error:', err.message));
socket.on('disconnect', (reason) => console.log('disconnected:', reason));
```
