The following page lists the Swagger files for available caDSR II REST APIs:
https://cadsrapi.cancer.gov/NCIAPIPortal/listAPIs
For example, the "Get Form Data with Collections" API accepts a Form ID and Protocol ID as input and returns all the components of the form: Form information, Modules, Questions, and Valid Values, including all instructions for each section of the form.

(TBD: Is there someone who can add an example URL for example 14, so I can resolve the TBD in caDSR II - caDSR APIs?)
