# GET /api/work/friends    → work profile
# GET /api/personal/friends → personal profile
# GET /api/friends          → default (work)

# Example: Send from different accounts
$ curl -X POST http://localhost:56789/api/work/messages/text \
  -H 'Content-Type: application/json' \

  -d '{"threadId":"456","message":"From personal"}'

# Real-time events are isolated per profile
$ curl -N http://localhost:56789/api/work/events     # work events only
$ curl -N http://localhost:56789/api/personal/events # personal events only

# Combine with auth: Add --auth-bearer or --auth-basic to protect all profiles.
# Example: zca serve --accounts work,personal --auth-bearer my-token

### Multi-Account Serving

Source: https://zca-cli.dev/docs/index

Instructions on how to serve multiple Zalo profiles concurrently from a single server instance.

```APIDOC
## Multi-Account Serving

### Description

Serve multiple Zalo profiles from a single server instance. Each profile can be accessed via a URL prefix, allowing for isolated API interactions per profile. It is recommended to limit to 3-5 profiles per instance due to resource consumption.

### Method

N/A (Server configuration and URL routing)

### Endpoint

`/api/{profile}/endpoint` (profile-specific)
`/api/endpoint` (default profile)

### Parameters

#### Server Configuration

- **CLI Flag**: Use `--accounts <profile1>,<profile2>,...` to specify the profiles to serve.

#### URL Routing

- Requests to `/api/{profile}/...` are routed to the specified profile.
- Requests to `/api/...` (without a profile prefix) are routed to the first profile listed in the `--accounts` flag (the default profile).

#### SSE Events

- Each profile has its own isolated SSE stream. Connect to `/api/{profile}/events` for profile-specific events.

### Request Example

```bash
# Serve 'work' and 'personal' profiles
$ zca serve --accounts work,personal

# Access endpoints for the 'work' profile
$ curl http://localhost:56789/api/work/friends

# Access endpoints for the 'personal' profile
$ curl http://localhost:56789/api/personal/friends

### Multi-Account API Server

Source: https://zca-cli.dev/docs/index

Instructions on how to serve multiple Zalo profiles from a single REST API server using the `--accounts` option.

```APIDOC
## Multi-Account API Server

**Description:** Serve multiple Zalo profiles from a single REST API server with the `--accounts` option. Each profile gets its own URL prefix for routing.

**Usage:**
```bash
$ zca serve --accounts <profile1>,<profile2>
```

**Example Workflow:**
```bash
# Serve multiple profiles from one server
$ zca serve --accounts work,personal

# Each profile gets its own URL prefix:
# GET /api/work/friends    → work profile
# GET /api/personal/friends → personal profile
# GET /api/friends          → default (work)

# Example: Send from different accounts
$ curl -X POST http://localhost:56789/api/work/messages/text \
  -H 'Content-Type: application/json' \
  -d '{"threadId":"123","message":"From work"}'

$ curl -X POST http://localhost:56789/api/personal/messages/text \
  -H 'Content-Type: application/json' \
  -d '{"threadId":"456","message":"From personal"}'

# Real-time events are isolated per profile
$ curl -N http://localhost:56789/api/work/events     # work events only
$ curl -N http://localhost:56789/api/personal/events # personal events only
```

**Security:** Combine with authentication using `--auth-bearer` or `--auth-basic`.
Example: `zca serve --accounts work,personal --auth-bearer my-token`
```

--------------------------------

### Activate zca-cli license

Source: https://zca-cli.dev/docs/index

Activates your zca-cli license by first obtaining a device support code and then using it with your license key. This is a prerequisite for full functionality.

```shell
# Get your device support code

.
# Activate with your license key
$ zca license activate "YOUR_LICENSE_KEY"
```

--------------------------------

### Echo Mode for Zalo Messages

Source: https://zca-cli.dev/docs/index

Enable echo mode to automatically reply with the same message received. This is ideal for testing purposes. You can configure it to echo all messages or only those starting with a specific prefix, which will be stripped from the reply.

```bash
# Echo all messages
$ zca listen --echo
.
# Echo only messages starting with "!"
$ zca listen --echo --prefix "!"
```

--------------------------------

### Activate zca-cli License

Source: https://zca-cli.dev/docs/index

```shell
# Example activation command (replace with actual command if provided)
# zca license activate YOUR_LICENSE_KEY
```

--------------------------------

### Get Zalo User ID for zca-cli

### Multi-Account with Environment Variable (zca-cli)

Source: https://zca-cli.dev/docs/index

Shows how to use the `ZCA_PROFILE` environment variable to set the active Zalo account for subsequent commands, simplifying multi-account management.

```bash
# Set profile for current session
$ export ZCA_PROFILE=work
.
# All commands now use the work profile
$ zca msg send 123456789 "Hello"
$ zca group list
```

--------------------------------

### Multi-Account Support

Source: https://zca-cli.dev/docs/index

Information on how to manage multiple Zalo accounts using profiles.

```APIDOC
## Using Profiles

### Method 1: `--profile` Flag
Use the `--profile` flag with any command to specify which profile to use.

### Usage Example
```bash
# Login to work account
$ zca --profile work auth login

# Send message from work account
$ zca --profile work msg send 123456789 "Hello from work"

# Login to personal account
$ zca --profile personal auth login

# Send from personal account
$ zca --profile personal msg send 987654321 "Hello from personal"
```

### Method 2: Environment Variable
Set the `ZCA_PROFILE` environment variable to specify the default profile for the current session.

### Usage Example
```bash
# Set profile for current session
$ export ZCA_PROFILE=work

# All commands now use the work profile
$ zca msg send 123456789 "Hello"
$ zca group list
```

### Profile Resolution Order
1. `--profile` CLI flag (highest priority)
2. `ZCA_PROFILE` environment variable
3. Default profile setting (set via account switch)
4. Falls back to "default" profile
```
