Using the Online Documentation

Previous Version

This is a previous version of the Ed-Fi ODS / API. Visit the Ed-Fi Tech Docs home page for a link to the current version, or the Ed-Fi Technology Version Index for links to all versions. 

Online documentation for the Ed-Fi ODS / API is available through Swagger UI, which is a visual and interactive documentation suite providing detailed descriptions for each resource as well as a simple way to test calls to the API in sandbox environments. 

Gaining Access to the Documentation

Before using the Swagger documentation interface, you must have access to an application key and secret. These are generally assigned by ODS / API platform administrators. Once you view the Swagger page, you will notice the inputs for the key and secret where you can click “Get Token” to exchange those for a temporary access token. This access token is used by the Swagger user interface while making calls on your behalf to the Ed-Fi ODS / API.

Browsing all resources

Because there are many resources exposed through the Ed-Fi ODS / API, they are broken into four separate sections in Swagger for easier browsing. The sections are Resources, Type, Descriptors, and Other. The resources exposed are, generally speaking, representative of entities from the Ed-Fi data model. This means that the entities will share names, organizations, and definitions across all parts of the Ed-Fi Data Standard, including the Ed-Fi XSD and the Ed-Fi ODS / API.

Resources

The Resources section is for main Ed-Fi API elements such as student, school, grade, and assessment. Each resource in this section maps one-to-one with Ed-Fi entities except for the domain aggregates. These domain aggregates have been created to wrap closely related entities into a single entity. Students and studentAssessments are examples of domain aggregates.

Types and Descriptors

The Types and Descriptors sections represent the types (e.g., academicSubjectTypes, addressTypes, accomodationTypes) and Ed-Fi Descriptors (e.g., academicSubjectDescriptors, accomodationDescriptors) from the Ed-Fi data model.

Other

The Other section contains the resources that aren't part of the data model. In the as-shipped solution, these resources include operations related to unique IDs and bulk uploads.

Viewing an individual resource

When expanding a resource, you will see that each resource is broken into sections based on the verbs supported.

Model vs. Model Schema

When the documentation for a GET operation is expanded, you will see the Model and Model Schema options. The model shows the type and description for each element within the resource. The model schema shows an example of the JSON representation for the resource.

Performing a Read and Write

To perform a read and write to the Ed-Fi ODS / API through the documentation UI, choose a resource and execute a GET that uses a “Get All” pattern by clicking the “Try it out!” button. To explore further, choose one of the returned resources and copy the JSON result then paste it into the associated POST text area. Remove the ETag, modify some of the remaining values, and click “Try it out!” for the POST. If the return code indicates a successful operation, a subsequent GET operation will return the modified resource with a new ETag

Checking for Errors

After executing an operation, an HTTP status code is displayed that shows the result of the operation along with a message where applicable. The system sends response codes along with human-readable error messages.

Developer Tools

To view the full request and response including the JSON and header values, you can use the developer tools included with the browser (typically with an F12 in most browsers).
