Defining Endpoints for Sub-resources

Within each sub-application, the URIs for all the main sub-resources can be mapped out.  For any operations applicable to all resources at an endpoint, you can simply use the top-level endpoint itself. For example, to retrieve all journal entries, your endpoint could be simply /api/journal.  If an operation is applicable to a specific resource, an ID is often used to indicate the specific sub-resource, as in /api/journal/{id}.

The URIs for top-level resources and sub-resources in the myJournal application are listed as the following:

/api/journal/api/journal/{id}

The /api/journal/{id} sub-resource is applicable to a specific journal entry.
