With the OpenFin Bloomberg Integration API, you can connect applications to the Bloomberg Terminal via the OpenFin InterApplicationBus (IAB).

To use the IAB, in place of calling connect(), call connectInterApplicationBus(); in addition to the same parameters used by connect(), you must also define a topic for the connection and an optional applicationId for the application to target.

📘

Note

If you do not specify an applicationId, all applications are targeted.

Any messages received over the IAB on the defined topic are considered to be a security; the security of the target panel or group are updated to match. When a source group security is changed, the new security is sent via the IAB as a message to the application matching the applicationId on the specified topic.

Example: Subscribe to an IAB topic with two applications

In the following example, two applications subscribe to the topic bbg-security.

// app1
// (security updates from Bloomberg received over IAB are output to the console)
fin.InterApplicationBus.subscribe({ uuid:'app2' }, 'bbg-security', console.log);

// app2
import { connectInterApplicationBus } from '@openfin/bloomberg';

Example: Create an IAB connection with a Launchpad group on a topic

The following example, creates an IAB connection on the topic bbg-security with the Group-A Launchpad group.

const connection = await connectInterApplicationBus(
  'bbg-security',
  'app1',
  'Group-A',
  'Group-A',
  console.log,
  console.error
  );

// app1
// Update Bloomberg to 'TSLA US Equity' using IAB
fin.InterApplicationBus.send({ uuid:'app2' }, 'bbg-security', 'TSLA US Equity');

// or
fin.InterApplicationBus.publish('bbg-security', 'TSLA US Equity');

Clean up

Remember to clean up resources when you are finished with a connection.

// app2
await connection.close();
