# Third-party integrations

> Pull generated media from external services into your posts

**Where:** the Integrations section

These are not social channels. They are external services that produce media,
connected so you can pull their output into a post without downloading and
re-uploading it.

## Connecting one

<Steps>
  <Step title="Open Integrations">
    The Integrations entry in the left rail.
  </Step>

  <Step title="Pick the service and paste your API key">
    You supply your own key, so usage is billed by that service to you, not
    through Postiz.
  </Step>

  <Step title="Use it in the composer">
    The **Import** button in the attachments bar now offers that service. Pick
    a generated asset and it attaches to the post.
  </Step>
</Steps>

Connected services are listed in the sidebar, each with a **Delete
Integration** option.

## What is available

The current integrations are AI video services, HeyGen being the main one.
Because each needs your own account and key, the exact list depends on what
your instance has enabled.

## How this differs from AI generation

|               | Third-party integration        | Built-in AI                               |
| ------------- | ------------------------------ | ----------------------------------------- |
| Where it runs | The external service           | Postiz                                    |
| Who pays      | You, directly to that service  | Your Postiz plan credits                  |
| What you get  | Whatever that service produces | Images and video from Postiz's generators |
| Setup         | Your API key                   | None on cloud                             |

Use a third-party integration when you already use that tool and want its
output in your calendar. Use [built-in AI](/general/composer/ai-and-imports) when
you just need an image or a short video and do not care which engine made it.
