Unlock Dynamic API Access with n8n Expressions
detail.loadingPreview
Learn how to securely and dynamically manage API credentials in n8n workflows. This template demonstrates using form inputs to set sensitive keys, enabling flexible and secure integrations.
About This Workflow
This n8n workflow template showcases a powerful pattern for managing API credentials dynamically using n8n's expression capabilities. Instead of hardcoding sensitive information, users can securely provide API keys via a user-friendly form. The workflow then captures this input and uses it to configure credentials for external services, such as the NASA API. This approach enhances security, simplifies credential management, and allows for greater flexibility in your automated processes. The example redirects the user to a NASA image of the day after successfully submitting their API key, demonstrating a complete, interactive workflow.

Key Features
- Dynamic Credential Management: Securely use user-provided API keys without hardcoding.
- Form-Based Input: User-friendly interface for submitting sensitive data.
- Expression Engine Integration: Leverage n8n's powerful expressions to set credentials on the fly.
- Secure Workflow Design: Reduces the risk of exposing credentials in your workflow definitions.
- Real-time Testing: Immediately test your integrations with live data.
How To Use
- Set up your NASA credential:
- Navigate to Credentials and create a new NASA credential.
- Hover over the API Key field.
- Toggle the Expression option on.
- In the API Key field, enter the expression:
{{ $json["Enter your NASA API key"] }}.
- Obtain a NASA API Key: Get your free API key from NASA's API website.
- Test the Workflow:
- Select Test workflow within your n8n instance.
- A form will appear. Enter your obtained NASA API key into the provided field.
- Submit the form. The workflow will execute, and you'll be redirected to a NASA image of the day, confirming successful credential utilization.
