OpenAI and Vector Store Tool 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 OpenAI or Vector Store Tool could already be your first step. To set this up, click "On App Event", search for either OpenAI or Vector Store Tool, and choose a trigger to kick off your workflow.

Drag the OpenAI node from the nodes panel on the left to the workflow canvas. Before dragging, choose the action OpenAI will perform.

Click on the OpenAI 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 OpenAI. 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 Vector Store Tool node from the nodes panel to the canvas. Before dragging, choose the action Vector Store Tool will perform.

Click on the Vector Store Tool 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 Vector Store Tool.

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 OpenAI node to the input of the Vector Store Tool 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 OpenAI, Vector Store Tool 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 OpenAI and Vector Store Tool integration is working as expected. Based on your configuration, data should flow from OpenAI to Vector Store Tool or vice versa. Easily debug your workflow: you can check past executions to isolate the mistake and fix it.
