Creating a subscription that consumes data with an API

Use the Navigator to create subscriptions that use the Consume Data REST API to consume the data from a specific topic in the

relational publication repository.

The following conditions must exist before you create a subscription:

An application or applications that consume data must exist. You can either use existing applications, or create and save new applications.

A relational topic to consume data from must exist. You can either use an existing topic, or create and save a new topic.

On the Navigator, click

New

Subscription

The

New Subscription

page appears.

Enter the subscription name. Optionally, enter a description for the subscription.

Select the subscription mode. Choose one of the following options:

Enable

. The subscription runs according to the schedule that you define in the

Schedule

page. You can also run the subscription manually from Cloud Integration Hub.

Pause

. The subscription does not run according to a schedule or by an external API. You can only run the subscription manually from Cloud Integration Hub to consume the delayed events.

Disable

. The subscription does not run according to a schedule or by an external API. You cannot run a disabled subscription manually from Cloud Integration Hub. If the related publication runs successfully, the disabled subscription doesn't create a delayed event. You cannot consume the published data when the subscription is in disabled mode.

Select

Consume data with an API

Optionally, enter a notification URL.

Cloud Integration Hub

sends notifications to this URL when data is ready to consume. You can either enter an unauthenticated URL or a basic authenticated URL.

For more information, see Subscription properties.

Select the application that subscribes to the data.

Select the topic that stores data in a relational database from which the application consumes the data and then click

. You can add as many topis as required.

Click

Save

You can copy the following URLs and use them in the request that runs the subscription:

URL of the REST API. Use this URL to consume the data.

URL of the Swagger structure for the topic that the subscription consumes data from.

If a Swagger structure base URL is configured for the organization, Cloud Integration Hub appends the base URL to the topic Swagger structure URL. For more information, see System Properties.
