Integrating AMQP with Orkes Conductor

This developer guide includes the steps to integrate AMQP with Orkes Conductor. This integration lets you connect your AMQP to Conductor to publish and receive messages from queues.

Get Configuration Credentials from AMQP

Before beginning the integration process in Orkes Conductor, you must obtain specific configuration credentials from AMQP, such as protocol, username, password, host, port, and virtual host.

Refer to the official AMQP documentation on how to get these configuration parameters.

Integrating with AMQP as a Message Broker

Now, you have the required configuration credentials from AMQP. Let’s integrate with Orkes Conductor.

  1. Navigate to Integrations from the left menu on the Conductor cluster.
  2. Click + New integration from the top-right corner of your window.
  3. Under the Message Broker section, choose AMQP.
  4. Click +Add and provide the following parameters:

Integration configuration for AMQP

Integration NameA name to identify your integration.
ProtocolSpecify the communication protocol to be used. It can be ‘amqp’ or ‘amqps’ (Recommended for secure connections).
UsernameSpecify the username to authenticate and authorize the connection.
PasswordSpecify the password associated with the provided username.
HostThe hostname of the server where the message broker is running.
PortThe port number on the host where the message broker is running. The default port for AMQPS is 5671, and the default port for AMQP is 5672.
Virtual HostSpecify the virtual host namespace. In AMQP, a virtual host is a namespace that allows multiple messaging environments to coexist within a single broker.
DescriptionProvide a description of the integration.
  1. You can toggle on the Active button to activate the integration instantly.
  2. Click Save.

Creating Event Handlers in Orkes Conductor

The integration is created successfully now. The next step is to create an event handler in Orkes Conductor.

To do this:

  1. Navigate to Definitions > Event Handler from the left menu on your Conductor console.
  2. Click + Define event handler option from the top-right corner of the window.
  3. Create an event handler with the following configurations:

Configuring Event Handler for AMQP Integration

Event Handler ParametersDescription
NameProvide a name to identify your event handler definition.
EventProvide the event integration you have created in the following format:

Type : Config Name : Queue Name

Example: amqp:amqp-test:queue-name

Notes: The drop-down automatically lists the integration you’ve added to the Conductor cluster. You can choose that and add the queue name you want to publish/receive messages.
ConditionProvide the ECMAScript to control the message processing if required. Check out the event handler documentation for more details.
ActionsChoose the required actions to be carried out on sending or receiving the events to/from AMQP. It can take the following values:
  • Complete Task
  • Terminate Workflow
  • Update Variables
  • Fail Task
  • Start Workflow
Each type of action requires and supports a certain set of input parameters. Check out the event handler documentation for more details.
ActiveSet this to true or false. It determines if the event handler is running or not.

A sample JSON for the event handler is as follows:

"name": "amqp-endpoint-event-handler",
"event": "amqp:amqptest:events-test-1",
"condition": "true",
"actions": [
"action": "start_workflow",
"start_workflow": {
"name": "event-handler-test",
"version": 1,
"correlationId": "",
"input": {
"payload": "${$}"
"expandInlineJSON": false
"active": true,
"evaluatorType": "javascript"

RBAC - Governance on who can use Integrations

Once the integration is added, the next step is to determine who can access these integrations.

The permissions can be granted to applications/groups within the Orkes Conductor cluster.

To provide explicit permission to Groups:

  1. From the left menu on your Conductor cluster, navigate to Access Control > Groups.
  2. Create a new group or choose an existing group.
  3. Under the Permissions section, click +Add Permission.
  4. From the Integrations sub-tab, choose the integration with required permissions.
  5. Click Add Permissions. This ensures that all the group members can access these integration models in their workflows.

Similarly, you can also provide permissions to applications.

Creating Workflow in Orkes Conductor

This step involves creating a workflow with an event task in Orkes Conductor. Here, we are utilizing the AMQP queue as a sink for the event.

You can quickly build a workflow from UI in Orkes Conductor.

For this,

  1. Navigate to Definitions > Workflow, and click the Define Workflow button.
  2. Create a workflow with an event task with the Sink in the format amqp:amqp-test:queue-name, where “amqp-test” is the integration name and “queue-name” is the queue to which Conductor should send/receive messages.

Executing Workflow in Orkes Conductor

The workflow can be run using different methods. You can use the Run Workflow button for quick testing, as shown in the image below:

Upon successful execution, you can verify the message's delivery through the AMQP console.

The action added in the event handler definition was to start the workflow event-handler-test. You can verify the same from the Executions > Workflow page.
