Implementation

The following methods of the target system connector interface defined in the connector SPI needs to be implemented for Account and Entitlement resources

Create Resource

public String postResource(String resource) {
    connect to the Google API using service account
    create user in Google Admin SDK using directory API
    throw appropriate exceptions if there is parsing error, conflicts or missing attributes
    return created user
}
JAVA

Update Resource

public String putResource(String id, String resource) {
	connect to the Google API using service account
    update user in Google Admin SDK using directory API
    throw appropriate exceptions if there is parsing error, not-found error or missing attributes
    return created user
}
JAVA

Patch Resource

public String patchResource(String id, String resource){
	connect to the Google API using service account
    Assign/Revoke Memberships for the User resource
    throw appropriate exceptions if any
    return user with current memberships
}
JAVA

Delete Resource

public void deleteResource(String id) {
	connect to the Google API using service account
    Delete user in Google Admin SDK using directory API
    throw appropriate exceptions if any
}
JAVA

Get Resource

public String getResourceById(String id, Set<String> attributes, Set<String> excludedAttributes) {
	connect to the Google API using service account
    Get the user in Google Admin SDK using directory API
      [attributes and excludedAttributes will be used to include and exclude memberships ONLY]
      populate entitlements if exclusively requested in attributes.
    throw appropriate exceptions if any. Not found exception if the User is not found in Google.
}
JAVA

Search Resource

public String searchResource(String resourceName, String filters) {
	The filter parameter is ignored
		return ALL(*) the instances of the given resource types .
		Use token to paginate over the list if there are multiple pages.
	return the list of resource objects matching the filter
}
JAVA

<Future scope> -

  • Complete implementation of Search

  • Design get user with membership to be more efficient (maybe cache results or find different API)

Risks

Due to how we retrieve Entitlements everytime, we run into risk of reaching API limits.
