Hi all,
According to the current Store REST API of APIM 3.0, using Subscription
resource[1], we can get the subscription details for a particular API.
The subscription resource is as follows.
*{*
*applicationId : "75834e14-d445-4e98-b90a-e2b726718384",*
*lifeCycleStatus : "ACTIVE",*
*policy : "Bronze",*
*subscriptionId : "a1439c91-78d9-49e6-bae8-7a514eb250fc"*
*apiIdentifier : "82079086-fd5c-452c-80da-1d0f06dc0252"*
*apiName : "TESTAPI"*
*apiVersion : "1.0.0"*
*}*
In here, the only detail to get information about the subscribed
application is the *applicationId*. For the API listing view of Store API,
we need to display the application names subscribed for the particular API.
To get that information with the existing implementation, we need to
first do a REST API call to get all subscriptions (list of Subscription
DTOs).
After that, we could either do a REST API call to get application name
(Application DTO) for the each Subscribed DTO or do a REST API call to get
all Applications (list of Application DTOs) and iterate it to get only the
application name of subscribed applications. For both cases, when the
number of subscriptions and the applications get larger, the number API
calls we would need will also become larger which could result in a
performance issue.
The same issue is handled in Publisher REST API by including Application
and API object in the SubscriptionDAO with required fields populated.
Please refer the mail thread [2].
Similarly, we can remove the applicationId and API related properties from
SubscriptionDTO in Store REST API and include the ApplicationInfoDTO and
ApiInfoDTO object as well. WDYT?
Would appreciate your comments and thoughts on this.
