n8n (short for “nodemation”) is a fair-code workflow automation tool that allows you to connect different services, APIs, and systems to automate tasks without heavy coding.

n8n supports custom nodes built by the community.

n8n provides built-in methods and variables for working with data and accessing n8n data. This section provides a reference of available methods and variables for use in expressions, with a short description.

Custom variables are read-only variables that you can use to store and reuse values in n8n workflows.
