**FastAPI** will create the object of type `BackgroundTasks` for you and pass it as that parameter.

## Create a task function { #create-a-task-function }

Create a function to be run as the background task.

It is just a standard function that can receive parameters.

   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.

3. **Testing**:
   - Include unit tests for new functionality or bug fixes.
   - Ensure existing tests pass (`make test`).
   - Document testing steps in the PR summary if manual testing was performed.

4. **Before Submitting**:
   - Run `make verify` to check formatting, linting, and tests.

This also means that in many cases you can pass the same object you get from a request **directly to the database**, as everything is validated automatically.
