Google Vertex Chat Model and QuickChart integration

Make sure you have n8n installed and running:

• Install n8n on any platform using npm or Docker;
• Or let n8n host it for you on its cloud infrastructure.

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow.

Add the starting point – a trigger on when your workflow should run: on schedule, on a webhook call, when called by another workflow, or manually. In some situations, either Google Vertex Chat Model or QuickChart could already be your first step. To set this up, click "On App Event", search for either Google Vertex Chat Model or QuickChart, and choose a trigger to kick off your workflow.

Drag the Google Vertex Chat Model node from the nodes panel on the left to the workflow canvas. Before dragging, choose the action Google Vertex Chat Model will perform.

Click on the Google Vertex Chat Model node, then click on the "Select credential" dropdown option next to the “Credential to connect with” field. Follow the authentication process to grant n8n access to your Google Vertex Chat Model. You can also share credentials you've created, and store sensitive credential information in an external vault using n8n's external secrets feature.

Drag the QuickChart node from the nodes panel to the canvas. Before dragging, choose the action QuickChart will perform.

Click on the QuickChart node, then click on the "Select credential" dropdown option next to the “Credential to connect with” field. Follow the authentication process to grant n8n access to your QuickChart.

Click on each node to configure its settings. You see the input data on the left. Manipulate the data in the middle by specifying parameters: resources, operations, etc. See the output on the right.

Connect the output of the Google Vertex Chat Model node to the input of the QuickChart node or swop nodes to route the integration the other way around.

Use n8n's core nodes to transform data the way you need and extend the integration:

• Splitting: IF and Switch
• Merging: Merge, Compare Datasets
• Looping: IF and Loop Over Items
• Waiting: Wait
• Creating sub-workflows: Execute Workflow and Execute Workflow Trigger
• Error handling: Stop And Error and Error Trigger
• Code: write custom JavaScript or Python and run it as a step in your workflow.

Once you've configured Google Vertex Chat Model, QuickChart and/or additional nodes make sure to save your workflow and activate it. Activating a workflow means that it will run automatically every time a trigger node receives input or meets a condition. By default, all newly created workflows are deactivated.

Run the workflow to see if Google Vertex Chat Model and QuickChart integration is working as expected. Based on your configuration, data should flow from Google Vertex Chat Model to QuickChart or vice versa. Easily debug your workflow: you can check past executions to isolate the mistake and fix it.
