Hi @andylunsford1 ,
We have checked the API documentation, but we could not find any details regarding whether the field is nullable or not.
For example: For Annotations api, in the documentation there are no details mentioned whether the fields in the annotations api could be nullable or not.

Is there any details regarding this.
