Dynamic NASA Credentials with n8n Expressions
Demonstrates setting NASA API credentials dynamically using expressions from a form input, enabling flexible authentication without hardcoding.
This n8n workflow showcases how to dynamically set credentials using expressions. It starts with a Form Trigger that collects a NASA API key from the user. The key is then injected into the NASA node's credential via an expression: {{ $json["Enter your NASA API key"] }}. Finally, it fetches the Astronomy Picture of the Day and redirects the user to the image URL via Respond to Webhook.
The primary benefit is flexibility in authentication—ideal for testing APIs or sharing workflows without expos
