# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

				if !ok || s.Path.Value != `"C"` {
					continue
				}
				sawC = true
				if s.Name != nil {
					error_(s.Path.Pos(), `cannot rename import "C"`)
				}
				cg := s.Doc
				if cg == nil && len(decl.Specs) == 1 {
					cg = decl.Doc
				}
				if cg != nil {
					if strings.ContainsAny(abspath, "\r\n") {
						// This should have been checked when the file path was first resolved,
