Rabbit MQ trigger

TheRabbit MQ trigger is aConnector Event trigger that lets you invoke an integration based on theRabbit MQ events that you've subscribed to in your Rabbit MQ connection.

Before you begin

If you plan to create or configure a new connection for theRabbit MQ trigger, make sure that you have the following IAM role on the project:

• Connector Admin (roles/connectors.admin)

For information about granting roles, seeManage access.

Grant the following IAM roles to the service account that you want to use for theRabbit MQ trigger:

• Application Integration Invoker (roles/integrations.integrationInvoker)

For information about granting roles to a service account, seeManage access to service accounts.

Add the Rabbit MQ trigger

To add aRabbit MQ trigger to your integration, perform the following steps:

1. In the Google Cloud console, go to theApplication Integration page.

   Go to Application Integration

2. In the navigation menu, clickIntegrations

   TheIntegrations List page appears listing all the integrations available in the Google Cloud project.

3. Select an existing integration or clickCreate integration to create a new one.

   If you are creating a new integration:

   1. Enter a name and description in theCreate Integration pane.
   2. Select a region for the integration.Note: TheRegions dropdown only lists the regions provisioned in your Google Cloud project. To provision a new region, ClickEnable Region. SeeEnable new region for more information.
   3. Select a service account for the integration. You can change or update the service account details of an integration any time from theinfoIntegration summary pane in the integration toolbar.Note: The option to select a service account is displayed only if you have enabled integration governance for the selected region.
   4. ClickCreate.

   The newly created integration opens in theintegration editor.

4. In theintegration editor navigation bar, clickTriggers to view the list of available triggers.
5. Click and place theRabbit MQ trigger element in the integration editor.

To configure theRabbit MQ trigger, you can either use an existing Rabbit MQ connection available in Integration Connectors, or create a new Rabbit MQ connection using the inline connection creation option.

Configure Rabbit MQ trigger using an existing connection

You can configure theRabbit MQ trigger using an existing Rabbit MQ connection in Integration Connectors. Note that theRabbit MQ trigger is anConnector Event trigger, therefore you can only use a Rabbit MQ connection with event subscription enabled to configure the trigger.

For information about how to configure aRabbit MQ trigger using a new Rabbit MQ connection, SeeConfigure Rabbit MQ trigger using a new connection

To configure aRabbit MQ trigger using an existing Rabbit MQ connection, perform the following steps:

1. Click theRabbit MQ trigger element in the integration editor to open the trigger configuration pane.

Trigger output

TheRabbit MQ trigger takes a couple of minutes to complete the event subscription configuration. You can view the status of your event subscription in the trigger configuration pane underEvent Subscription details.

TheRabbit MQ trigger indicates the status of an event subscription using the following states:

• restart_altCreating: Indicates that the trigger is subscribing to the event subscription.
• check_circleActive: Indicates that the trigger is successfully subscribed to an event subscription.
• errorError: Indicates that the there is an issue with the configured event subscription.

In addition to the event subscription status, theEvent Subscription details section also displays other details such as connection region, connection name, and event subscription name.

The following image shows a sample layout of the Rabbit MQ trigger configuration pane:

Trigger output variable

For each event, theRabbit MQ trigger generates aConnectorEventPayload output variable (in JSON format) which you can use in your downstream tasks. The output variable will have the payload from your Rabbit MQ event. For example:

{"message":"Hello world","messageContentType":"Text"}
