Who is this workflow for? This workflow enables dynamic credential management in n8n by allowing users to input their NASA API key through a form. The entered key is then utilized in the NASA node to authenticate and retrieve the NASA picture of the day, streamlining the authentication process without hardcoding sensitive information..

What does this workflow do?

  • Form Input for API Key:
  • The workflow begins with a form that prompts the user to enter their NASA API key.
  • Setting Credentials Dynamically:
  • The entered API key is captured using an expression: {{ $json["Enter your NASA API key"] }}.
  • This expression is set in the NASA node’s API Key field, enabling dynamic authentication.
  • NASA Node Execution:
  • The NASA node uses the provided API key to authenticate the request.
  • Upon successful authentication, it retrieves the NASA picture of the day.
  • Testing the Workflow:
  • Users can test the workflow by obtaining a NASA API key from the NASA API portal.
  • After entering the key in the form, executing the workflow will display the NASA picture of the day, confirming successful authentication and data retrieval.

🤖 Why Use This Automation Workflow?

  • Enhanced Security: Avoids storing API keys directly in the workflow, reducing the risk of exposure.
  • Flexibility: Allows different users to input their own API keys, making the workflow reusable across various accounts.
  • Ease of Use: Simplifies the process of updating or changing API keys without modifying the workflow structure.

👨‍💻 Who is This Workflow For?

This workflow is ideal for individuals and teams who:

  • Regularly interact with APIs requiring dynamic authentication.
  • Need to maintain secure handling of sensitive credentials.
  • Use n8n for automating tasks and require flexibility in credential management.

🎯 Use Cases

  1. Multi-User Applications: Applications where multiple users need to authenticate with their own API keys.
  2. Secure Integrations: Integrating services that require frequent credential updates without altering the workflow.
  3. Dynamic API Access: Scenarios where API keys are generated or rotated regularly, necessitating a dynamic approach to credential management.

TL;DR

This n8n workflow template offers a secure and flexible method to manage API credentials dynamically using expressions. By allowing users to input their NASA API key through a form, it ensures secure authentication and seamless access to the NASA picture of the day, enhancing both security and usability in automated workflows.
