n8n GraphQL Schema

n8n does not currently expose a public GraphQL API. The primary programmatic interface is a REST API documented at [https://docs.n8n.io/api/api-reference/](https://docs.n8n.io/api/api-reference/). However, n8n's internal data model — covering workflows, nodes, executions, credentials, users, projects, webhooks, and more — maps cleanly to a GraphQL type system, and this schema represents a conceptual GraphQL surface over that model.
