API Routes - Assessment-VDG

Routes are names used to access API endpoints and are used in API URLs. This section describes the patterns and conventions for route naming in the Ed-Fi ODS / API.

Route Patterns in Ed-Fi APIs

The Ed-Fi ODS / API uses the following route structure to support multiple Extensions and to provide support for API versioning:

Notes:

¹ School Year is optional in the route.
² It is important to note the distinction between the Extended Ed-Fi Resources (which collect additional data for an existing Ed-Fi core resource using the _ext field in the JSON payload) and Host & Domain Resources (which create entirely new resource endpoints).
³ Composites are treated as a reserved word.
⁴ Endpoint for identity feature is clearly separated to allow separate versioning for this feature and to support implementations that are not using this optional feature.

Extensibility 

The Ed-Fi API is extensible. Your application should not have to use extensibility in most cases, but it is covered here in case you do encounter it.

There are 2 kinds of extensibility:

• An existing API resource can be extended to have additional elements. In this case, the extension elements (fields, etc.) are added to the API resource in an "_ext" JSON Object.
• A new API resource can be added to the API. In this case, the extension element is signaled via a new route.

Examples of both are provided below.

Example: Extended Ed-Fi School Resource (Route: /data/v3/ed-fi/schools)

{
    "studentUniqueId": "397589871",
    "firstName" : "John",
    "lastSurname:" "Ortiz",
    
[etc...]
 
    “_ext” : {
        “SomeState” : {
            “tribalAffiliation” : “Pascua Yaqui”,
            [etc...]
        }
    }
}

Example: TalentMgmt Applicant Resource (Route: data/v3/talentMgmt/applicants)

{
    "id": "string",
    "applicantIdentifier": "397589871",
    "educationOrganizationReference": {
      "educationOrganizationId": 255901,     
    },
    "addresses": [
      {
 		[etc...]
      }
	[etc...]
}
