GraphQL and Postgres integration

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

How to connect GraphQL and Postgres

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.

GraphQL and Postgres integration: Create a new workflow and add the first step

Build your own GraphQL and Postgres integration

Create custom GraphQL and Postgres workflows by choosing triggers and actions. Nodes come with global operations and settings, as well as app-specific parameters that can be configured. You can also use the HTTP Request node to query data from any app or service with a REST API.
