There’s not an official tutorial for autotile, but this may help you:

I don’t think this is what he meant to ask.
Currently, when you are trying to set tiles via code, you have to manually specify a vector representing a bitmask index required to select a sprite corresponding to autotile.
There is no way to put a sprite in the valid fashion from the very start, but what you can do, is to put all the sprites in the corresponding positions and call update_bitmask_region after that.

Here is an example from my code:

private void InstanciateTilemap(Node scene)
        var set = GD.Load<TileSet>("res://TileSets/Default.tres");

        var map =
            new TileMap
                TileSet = set,
                CellSize = new Vector2(32, 32),
                CellQuadrantSize = 16
        var size = OS.WindowSize;
        for(var horizontalIndex = 0; horizontalIndex < 16; horizontalIndex++)
         for(var verticalIndex = 0; verticalIndex < 16; verticalIndex++)

            new Vector2(),
