How to connect Google Cloud Pub\Sub and Caption AI
Create a New Scenario to Connect Google Cloud Pub\Sub and Caption AI
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a Google Cloud Pub\Sub, triggered by another scenario, or executed manually (for testing purposes). In most cases, Google Cloud Pub\Sub or Caption AI will be your first step. To do this, click "Choose an app," find Google Cloud Pub\Sub or Caption AI, and select the appropriate trigger to start the scenario.

Add the Google Cloud Pub\Sub Node
Select the Google Cloud Pub\Sub node from the app selection panel on the right.

Authenticate Caption AI
Now, click the Caption AI node and select the connection option. This can be an OAuth2 connection or an API key, which you can obtain in your Caption AI settings. Authentication allows you to use Caption AI through Latenode.
Configure the Google Cloud Pub\Sub and Caption AI Nodes
Next, configure the nodes by filling in the required parameters according to your logic. Fields marked with a red asterisk (*) are mandatory.
Set Up the Google Cloud Pub\Sub and Caption AI Integration
Use various Latenode nodes to transform data and enhance your integration:
- Branching: Create multiple branches within the scenario to handle complex logic.
- Merging: Combine different node branches into one, passing data through it.
- Plug n Play Nodes: Use nodes that don’t require account credentials.
- Ask AI: Use the GPT-powered option to add AI capabilities to any node.
- Wait: Set waiting times, either for intervals or until specific dates.
- Sub-scenarios (Nodules): Create sub-scenarios that are encapsulated in a single node.
- Iteration: Process arrays of data when needed.
- Code: Write custom code or ask our AI assistant to do it for you.

Save and Activate the Scenario
After configuring Google Cloud Pub\Sub, Caption AI, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Google Cloud Pub\Sub and Caption AI integration works as expected. Depending on your setup, data should flow between Google Cloud Pub\Sub and Caption AI (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Google Cloud Pub\Sub and Caption AI
Google Cloud Pub\Sub + Caption AI + Slack: When a new audio message is published to a Google Cloud Pub/Sub topic, Caption AI generates captions for the audio, and then the original audio message and the generated captions are posted to a designated Slack channel.
Google Cloud Pub\Sub + Caption AI + Google Cloud Storage: Upon receiving an audio message through Google Cloud Pub/Sub, Caption AI creates captions for the audio. Both the original audio file and its corresponding captions are then stored in a specified Google Cloud Storage bucket.
