Publishers

Publishers are the applications or partners that send data to Sensedia Events Hub, communicating events that will be distributed to subscribers.

Publishers send events to topics, which define the publication URL. Therefore, in the publisher registration process, you need to enable the topics that each publisher can send requests to.

List of publishers

On the Publishers screen, you can see all your publishers and register new ones.

You can search for a specific publisher using the filters at the top of the page. They allow you to search by:

  • start and end of creation date;

  • publisher’s name;

  • responsible developer’s email;

  • client ID;

  • status; or

  • handler’s name.

Use the Order by field to define the order of the list. You can choose to view by the latest or oldest creation date, or in alphabetical order.

By clicking on a publisher’s name, you are directed to the Overview screen. There, you can:

  • view and edit the publisher’s information using the Edit Publisher button;

  • delete the publisher by clicking on the icon icon delete;

  • enable or disable topics for the publication with the Edit Enabled Topics button.

    • Name: name of the publisher, which must be unique;

    • Status: choose between approved, pending, rejected or canceled;

    • Description: non-mandatory field to include a description;

    • Developer: email of the developer responsible for the publisher;

    • Client ID: the publisher’s identification for when the event is received by the Events Hub.

  2. Click Save and Next;

  3. Click on ADD ENABLED TOPICS to link the publisher to the topics;

The Topics section is used to enable the topics that the publisher can send events to. Topics are created through handlers and are enabled in contexts. This allows you to use specific contexts for publishers in the same topic.

Imagine that you want "Publisher A" to publish events for the "Outlet" topic.
At the same time, your development team needs to test this same topic, but using a mock authorization endpoint.
For this, you can create a testing context called "Testing", for example, and enable the "Outlet" topic for both the "Default" and the "Testing" context.

Authorization endpoints are defined by context. This allows you to set up a mock for "Testing" and keep the default context with the actual authorization.
