## Inputs & Outputs

**Inputs:**
- `in` -- Text, image, or video content to publish (depending on selected action).

**Outputs:**
None. This is a terminal output node.
## Best Practices
- Use `post-text` for text-only updates and `post-image` or `post-video` when media is available.
- Keep captions professional and under 3,000 characters.
- Use landscape format (1200x627) for images, as it displays best in the LinkedIn feed.
- Connect your LinkedIn account on the Integrations page before use.

## Common Use Cases
- Sharing AI-generated content or insights on LinkedIn.
- Publishing video content to a professional audience.
- Automating thought-leadership content distribution.
- Cross-posting workflow outputs alongside other social platforms.

## Tips
- LinkedIn supports three distinct actions (text, image, video), unlike platforms that combine media types.
- OAuth tokens are encrypted at rest using AES-256-GCM.
- One LinkedIn account can be connected per user.
- For best engagement, pair media posts with compelling caption text rather than relying on the visual alone.
