IBM MQ trigger

The IBM MQ trigger is a Connector Event trigger that lets you invoke an integration based on the IBM MQ events that you've subscribed to in your IBM MQ connection.

Important: Integration Connectors is a billable component of Google Cloud. For information about the costs and charges of using Integration Connectors, see Integration Connectors pricing.

Before you begin

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

• Connectors Admin (roles/connectors.admin)

For information about granting roles, see Manage access.

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

• Application Integration Invoker (roles/integrations.integrationInvoker)

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

Trigger output

The IBM 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 under Event Subscription details.

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

• Creating: Indicates that the trigger is subscribing to the event subscription.
• Active: Indicates that the trigger is successfully subscribed to an event subscription.
• Error: Indicates that the there is an issue with the configured event subscription.

In addition to the event subscription status, the Event 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 IBM MQ trigger configuration pane:

Trigger output variable

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

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