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:

DescriptionODS / API Route
Base URI

/{api_area}/{version}/{instance}1/{year}2

Examples:
/data/v3
/composites/v1
/identity/v2

Basic Relative URL Format

Data Management Resources:
…/{org}/{resource}

API Composites:
.../{org}/{category}/{resource}

Examples
Resources (Ed-Fi)/data/v3/ed-fi/schools
Descriptors (Ed-Fi)/data/v3/ed-fi/termDescriptors
Resources (Host Extensions)3/data/v3/TX/leavers
Resources (Domain Extensions)3/data/v3/talentMgmt/applicants
Composites (Ed-Fi)4/composites/v1/ed-fi/assessment/studentAssessments
Composites (Host Organization)/composites/v1/MI/enrollment/Schools
Composites Based on Domain or Host ExtensionsUnsupported
Identity/identity/v2/identities5

Notes:

1 - Instance is optional in the route.
2 - School Year is optional in the route.
3 - 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).
4 - Composites are treated as a reserved word.
5 - 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.

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

Sample JSON Payload for extended Student
{
    "studentUniqueId": "397589871",
    "firstName" : "John",
    "lastSurname:" "Ortiz",
    
[etc...]
 
    “_ext” : {
        “SomeState” : {
            “tribalAffiliation” : “Pascua Yaqui”,
            [etc...]
        }
    }
}

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

Sample JSON Payload for Applicant
{
    "id": "string",
    "applicantIdentifier": "397589871",
    "educationOrganizationReference": {
      "educationOrganizationId": 255901,     
    },
    "addresses": [
      {
 		[etc...]
      }
	[etc...]
}
