## What does nylas slack send do?

The nylas slack send command posts a message to any Slack channel your token has access to. Specify the channel with --channel and the message with --text. To reply in a thread, use the dedicated nylas slack reply command instead.

## Usage

```bash
nylas slack send --channel CHANNEL --text TEXT
```

## Flags

| Flag | Description |
| --- | --- |
| --json | Output as JSON |
| --no-color | Disable color output |
| --verbose(-v) | Enable verbose output |
| --config | Custom config file path |
| --help(-h) | Show help for the command |
| --limit | Limit results (most list commands) |
| --yes(-y) | Skip the send confirmation prompt |
| --channel | Channel ID or name |
| --text | Message text to send |
| --channel-id | Channel ID |

## Examples

The nylas slack send command posts a message to any Slack channel your token has access to.

### Send to a channel

```bash
nylas slack send --channel general --text "Deploy complete for v2.4.1"
```

### Skip the confirmation prompt in scripts

```bash
nylas slack send --channel deploys --text "Build #482 green" --yes
```

## Example output

```text
Send to #general as Alice Chen:
  "Hello team!"

✓ Message sent to #general
```

## Troubleshooting

### not_in_channel error

Invite the bot to the channel first with /invite @your-bot-name, or use a user token instead.

### Message sends but shows as bot instead of user

Bot tokens (xoxb-) always post as the bot. Use a user token (xoxp-) to post as yourself.
