What it does
An n8n workflow that shows how to set a node's credentials with an expression. A form asks for an API key, and the NASA node uses that key to authenticate its request. The steps cover turning on expression mode for the API key field and testing the workflow with a form submission.
Use cases
- 01Let a user enter their own API key in a form
- 02Test a node with keys that change between runs
- 03Learn how n8n expressions read form fields
