# attachment_create

> Link an issue to something outside Linear. Linear deduplicates by URL: creating an attachment whose URL is already on the issue updates that one rather than adding a second.

<div className="tool-route"><span className="tool-row-method" data-method="POST">POST</span><code>{"https://api.linear.app/graphql"}</code></div>

```python linear_attachment_create.py theme={null}
from charter.packs import linear

result = await linear.attachment_create.ainvoke({"variables": ...})
```

<Note>
  Posts a GraphQL document to `POST /graphql`, as every tool in this pack does.
