Definitions for the CDSHooksRequest logical model.
Guidance on how to interpret the contents of this table can be found here
0. CDSHooksRequest | |
Definition | The response to the discovery endpoint |
Short | The response to the discovery endpoint |
Logical Model | Instances of this logical model are not marked to be the target of a Reference |
