Rest Api. JWT auth. How to make api stateless?

Question

Here are endpoints I have

public static void RegisterTodoListEndpoints(this IEndpointRouteBuilder app)
{
var group = app.MapGroup("api/lists").RequireAuthorization();

/// <summary>
/// Returns lists of current user (Id, Title, Ammount of tasks)
/// </summary>
group.MapGet("", GetAllTodos);

/// <summary>
/// Create new todo list
/// </summary>
group.MapPost("", CreateTodoList);

/// <summary>
/// Return list and its tasks. 403 if user is not owner of list
/// </summary>
group.MapGet("/{listId}", GetTodoListById);

/// <summary>
/// Deletes list and its tasks. 403 if user is not owner of list
/// </summary>
group.MapDelete("{listId}", DeleteTodoList);

/// <summary>
/// Creates new task. 403 if user is not owner of list
/// </summary>
group.MapPost("/{listId}/tasks", CreateTodoTask);

/// <summary>
/// Updates new task. 403 if user is not owner of list
/// </summary>
group.MapPatch("{listId}/tasks/{taskId}", UpdateTodoTask);

}

Lets take a look at GetTodoListById. Using ClaimsPrincipal makes it not stateless?

private static async Task<IResult> GetTodoListById(
ISender sender,
ClaimsPrincipal claimsPrincipal,
[FromRoute] int listId)
{
var userId = int.Parse(claimsPrincipal.FindFirstValue(ClaimTypes.NameIdentifier)!);
var query = new GetTodoListByIdQuery(listId, userId);
var response = await sender.Send(query);

if (response.IsFailure)
{
return response.AsTypedErrorResult();
}
return TypedResults.Ok(response.Value);

}

These are the best thing for your help. Our Sololearn already made community tutorials on API! Take a look at these:

You can find it by your own. Just go the practice section and at the top your find a search bar where you need to search API. That's it. Already a tutorial on RESTful API with Node.js & Express is available there or check the first link I provided.
