Klaviyo and Postgres integration

Save yourself the work of writing custom integrations for Klaviyo and Postgres and use n8n instead. Build adaptable and scalable Marketing, Development, and Data & Storage workflows that work with your technology stack. All within a building experience you will love.

How to connect Klaviyo and Postgres

  • Step 1: Create a new workflow
  • Step 2: Add and configure nodes
  • Step 3: Connect
  • Step 4: Customize and extend your integration
  • Step 5: Test and activate your workflow

Step 1: Create a new workflow and add the first step

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: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Step 2: Add and configure Postgres and Klaviyo nodes (using the HTTP Request node)

You can find the Postgres node in the nodes panel and drag it onto your workflow canvas. To add the Klaviyo app to the workflow select the HTTP Request node and use the generic authentication method to make custom API calls to Klaviyo. Configure Klaviyo and Postgres one by one: input data on the left, parameters in the middle, and output data on the right.

Step 3: Connect Postgres and Klaviyo

A connection establishes a link between Postgres and Klaviyo (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.

Step 4: Customize and extend your Postgres and Klaviyo integration

Use n8n's core nodes such as If, Split Out, Merge, and others to transform and manipulate data. Write custom JavaScript or Python in the Code node and run it as a step in your workflow. Connect Postgres and Klaviyo with any of n8n’s 1000+ integrations, and incorporate advanced AI logic into your workflows.

Step 5: Test and activate your Klaviyo and Postgres workflow

Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from Klaviyo to Postgres or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.
