Before importing/making annotations, we first need to create the needed annotation classes, such as a polygon cell or a bounding box car.

Every annotation class has exactly one main type (polygon, bounding box etc.) and zero or more subtypes (attributes, text etc.).

Classes are share across the whole team, this requires the name to be unique.

Each class needs to be associated with every dataset that wants to use them. This is done by adding the dataset id/slug to the datasets field in Update Annotation Class.

In the table below are each annotation type listed, note that the API uses the slug instead of the name.

Name	Slug	Type
Polygon	polygon	Main
Bounding Box	bounding_box	Main
Tag	tag	Main
Skeleton	skeleton	Main
Keypoint	keypoint	Main
Line	line	Main
Ellipse	ellipse	Main
Mask	mask	Main
Attributes	attributes	Sub
Text	text	Sub
Directional Vector	directional_vector	Sub
Instance ID	instance_id	Sub
