Subscription ManagementExample of Implementing a REST API

Let’s manage subscriptions to FME Server topics using a web service

Subscription ManagementExample of Implementing a REST API

Entities: devices, email addresses, WebSocket streams

Topics: places to send messages to and read messages from

Subscriptions: agreement for an entity to receive messages from a topic

Subscription ManagementExample of Implementing a REST API

Let’s make it RESTful by using the URL pattern to specify the resource to act on

Subscription ManagementExample of Implementing a REST API

The Subscription Manager REST API:

subscription_manager.fmw/entity/<id>/add?type=<email|apns|gcm|websockets>subscription_manager.fmw/subscription/<topic_name>/<id>/addsubscription_manager.fmw/subscription/<topic_name>/<id>/add?confirm_token=******subscription_manager.fmw/subscription/<topic_name>/<id>/deletesubscription_manager.fmw/subscription/<topic_name>/<id>/delete?confirm_token=******
