# Slack

> Workspace messaging via webhooks. Automate internal communications.

Like Discord, Slack uses a webhook-based approach for posting messages.

## Quirks & Gotchas

### Webhook-Based Posting

Slack requires you to connect a workspace and select channels. We use incoming webhooks to post messages.

* You must be a workspace admin to connect.
* Posts appear as a bot message in the selected channel.

### Channel Selection Required

You must specify a `channelId` in your post data. Available channels are in `socialAccount.channels`.

### Generous Character Limit

Slack allows up to **30,000 characters** per message-much more than most platforms.

### Custom Bot Identity

Like Discord, you can customize the bot appearance:

* `username`: Up to 80 characters.
* `avatarUrl`: A URL to an image for the bot's avatar.

## Analytics

For general analytics concepts, see the [Analytics Overview](/api-reference/analytics).

Slack does not provide analytics via its API. All metrics return `0`. It's a workspace tool, not a social media platform.

| Metric        | Note        |
| :------------ | :---------- |
| `impressions` | Returns `0` |
| `views`       | Returns `0` |
| `likes`       | Returns `0` |
| `comments`    | Returns `0` |

```javascript theme={null}
await bundle.post.create({
