Hi Sumedha, In Current APIM, following are the status of a API Subscriptions
BLOCKED, PROD_ONLY_BLOCKED, UNBLOCKED, ON_HOLD, REJECTED Consider following scenario/use case and relevant status of API subscriptions 1. An Application subscribes an API - UNBLOCKED 2. Publisher blocks the Application - BLOCKED 3. Application unsubscribes the API - The entry will be removed from DB 4. Same Application subscribes to same API - UNBLOCKED (A new entry in the DB) In this case, the Application was blocked by the publisher. Since we have deleted the entry from DB, Application can invoke the API after re subscribing to the API With this implementation (keeping one status for API subscriptions), there can be multiple scenarios having same problem. So, we have to introduce two status for API subscription. 1. One for keeping the application state - SUBSCRIBE/UNSUBSCRIBE 2. Another for keeping publisher's action on the subscription - BLOCK/UNBLOCK/PROD_ONLY_BLOCKED With the introduction of these two status, please find the new status for the above use case. 1. An Application subscribes to an API - SUBSCRIBE,UNBLOCKED 2. Publisher blocks the Application - SUBSCRIBE,BLOCKED 3. Application unsubscribes the API - UNSUBSCRIBE,BLOCKED 4. Same Application subscribes to same API - SUBSCRIBE,BLOCKED So, even the application re subscribing to API, it can't invoke. Here we don't delete any subscription entries from DB. So we can find the history of the subscription of a API -- Thanks Abimaran Kugathasan Software Engineer | WSO2 Inc Data & APIs Technologies Team Mobile : +94 77 1708229 <http://stackoverflow.com/users/515034> <http://lk.linkedin.com/in/abimaran> <http://www.lkabimaran.blogspot.com/> <https://github.com/abimaran> <https://twitter.com/abimaran>
