The response field, which is part of the callback POST request and permanently stored as part of the task object, will contain an annotations field (and a global_attributes field, if Global Attributes were specified in the task creation request).
The annotations field will contain an array of Annotation objects. The schema of each Annotation object depends on the Geometry of the Annotation. See the Boxes, Polygons, Lines, Points, Cuboids, and Ellipses sections for descriptions of the schemas.
