Short answer

How can I trigger microservices using my AI?

Your AI uses the publish_message tool to push data to a specific Google Pub/Sub topic. This acts as a signal for your workers or downstream services to start their next task. You'll see how this triggers specific system events below.

Where signals land.

Where your signals land.

The AI directs information to specific destinations based on your instructions.

WORKER

Triggered microservices

The AI sends a message to a topic that your worker is listening to. This kicks off automated processing without you touching a terminal.

LOGS

Event tracking

Your AI publishes status updates to a topic that feeds into your logging or monitoring stack. You get an immediate record of the event.

HUMAN

Manual intervention

If a task requires a person, the AI can send a notification to a topic that alerts your monitoring dashboard. You decide when to step in.

DATA

Downstream updates

The AI pushes event data to a topic that feeds into your database or analytics engine. Your data stays current with your AI's actions.

The workflow

What your AI does when a task arrives.

The AI handles the handoff between your conversation and your backend infrastructure.

  1. Analyze the event

    Your agent looks at the completed task or user event to determine what information needs to be sent.

    publish_message

  2. Format the payload

    The AI structures the data into a message format that your specific microservice expects to receive.

    publish_message

  3. Send the signal

    The AI pushes the formatted message directly to your designated Google Pub/Sub topic.

    publish_message

  4. Confirm delivery

    The AI verifies the message was sent successfully so you know the downstream service has been notified.

FAQ

How this task behaves.

  • 01

    Can the AI create new Pub/Sub topics?

    No. The AI can only publish messages to topics that already exist in your Google Cloud project.

  • 02

    Does the AI manage my Google Cloud permissions?

    No. You must set up the necessary IAM permissions in your Google Cloud console so the connection has permission to publish.

  • 03

    Can I send complex JSON payloads?

    Yes. You can instruct your AI to format the message as a JSON object for your microservices to parse.

  • 04

    Will the AI delete messages from my topic?

    No. This connector only has the ability to publish messages. It cannot read, delete, or manage existing messages in the topic.

  • 05

    Can the AI trigger a function directly?

    The AI triggers the topic. If you want to trigger a Cloud Function, you should set that function to trigger off the Pub/Sub topic the AI is writing to.
