Data editing

n8n allows you to edit pinned data. This means you can check different scenarios without setting up each scenario and sending the relevant data from your external system. It makes it easier to test edge cases.

For development only

Data editing isn't available for production workflow executions. It's a feature to help test workflows during development.
