# Retrieve a Registration Provider

`GET /providers/registrations/{provider_id}/`

Retrieves the details of a Registration Provider.
#### Returns
Returns a JSON object with a `data` key containing the representation of the requested Registration Provider, if the request is successful.

If the request is unsuccessful, an `errors` key containing information about the failure will be returned. Refer to the [list of error codes](#tag/Errors-and-Error-Codes) to understand why this request may have failed.

#### Acceptable Subjects Structure
Each Registration Provider specifies acceptable subjects.
`subjects_acceptable` is an array found in `attributes`.
Subjects consist of general parent subjects (e.g., Engineering), more specific child subjects (e.g., Aerospace Engineering), and even more specific grandchild subjects (e.g., Aerodynamics and Fluid Mechanics). Subjects can only be nested 3 deep.


    "subjects_acceptable": [
        [
            [
                # Parent Subject:
                # Architecture
                "584240d954be81056ceca9e5",

                # Child Subject:
                # Architectural Engineering
                "584240da54be81056cecac87"
            ],
            # Include all Architectural Engineering's children:
            true
        ],
        [
            [
                # Parent Subject:
                # Engineering
                "584240da54be81056cecaca9",

                # Child Subject:
                # Aerospace Engineering
                "584240db54be81056cecacd6",

                # Grandchild Subject:
                # Aerodynamics and Fluid Mechanics
                "584240da54be81056cecaa74"
            ],
            # All nestings 3 deep must be false
            false
        ]
    ]

The above structure would allow Architecture, Architectural Engineering, all of Architectural Engineering's children, Engineering, Aerospace Engineering, and Aerodynamics and Fluid Mechanics.
