FME Flow: 2024.2

Subscriptions

Select Automations > Notifications > Subscriptions.

Subscriptions receive notifications from topics, and deliver the content to clients over a supported protocol. For more information, see Notification Service.

Click on the Subscriptions tab to open the table view of subscriptions. You will see a list of subscriptions and the topics to which they are subscribed. Some subscriptions are already created for you by FME Flow. For more information about these subscriptions, see Monitoring FME Flow Events from Topics.

Creating a Subscription

Tip  As an alternative, consider building your notification on the Automations page—an easy-to-use interface for creating workflows that can comprise multiple publishers, subscribers, and other notification mechanisms.

To create a subscription, click New. Alternatively, select an existing subscription that is similar to the one you want to create, and click Duplicate.

  1. Provide a name for the subscription.
  2. Select a protocol. (See below for descriptions)

  3. Specify the Topics you want to subscribe to using the drop-down selector. To create a topic and use it right away, click +.

  4. Protocol-specific fields will appear underneath (see below). Complete these fields. For more information, see Subscribers.
  5. Click OK.
