Dynamically Set NASA API Credentials Using n8n Expressions

This workflow demonstrates how to dynamically set API credentials using expressions in n8n. It collects a NASA API key via a form and uses it to authenticate requests to the NASA API.

n8n

This workflow is designed to dynamically handle credentials by accepting a user-provided API key through a form. The key is then used to authenticate requests to the NASA API, demonstrating the power and flexibility of n8n expressions. The workflow includes a form trigger to collect the API key, a NASA node to make authenticated requests, and a webhook response node to redirect users to the NASA Picture of the Day.
