# issues_add_labels

> Add labels to an issue, keeping the ones already on it. Use this rather than `issues_update` to label something: `issues_update` *replaces* the whole set, so adding one label there removes the rest.

<div className="tool-route"><span className="tool-row-method" data-method="POST">POST</span><code>{"https://api.github.com/repos/{owner}/{repo}/issues/{issueNumber}/labels"}</code></div>

```python github_issues_add_labels.py theme={null}
from charter.packs import github

result = await github.issues_add_labels.ainvoke({"owner": ..., "repo": ..., "issueNumber": ..., "labels": ...})
```

<Note>
  Requires `repo`, `read:user`.
