Automate API Key Management with Dynamic Credentials
detail.loadingPreview
Securely manage API keys and credentials within your workflows using dynamic expressions. This n8n workflow demonstrates how to securely pass sensitive information like API keys through forms and use them to authenticate with services like NASA.
About This Workflow
This n8n workflow showcases a powerful method for managing sensitive credentials by leveraging dynamic expressions. Instead of hardcoding API keys, users can securely input them via a form. These inputs are then dynamically used to authenticate nodes, such as the NASA node, in real-time. This approach significantly enhances security and flexibility, allowing for workflows that adapt to different authentication requirements without manual reconfiguration. The workflow concludes by redirecting the user, demonstrating the seamless integration of dynamic credentials into an automated process.
Key Features
- Dynamic Credential Injection: Pass sensitive data like API keys directly from user input or other workflow steps.
- Secure Input Handling: Utilize n8n forms to collect sensitive information without exposing it directly in workflow configurations.
- Real-time Authentication: Authenticate services using credentials that are determined during workflow execution.
- Simplified API Integration: Easily connect to services that require API keys, like NASA's Picture of the Day API.
How To Use
- Configure NASA Credential:
a. Create a new NASA credential in n8n.
b. Hover over the API Key field.
c. Toggle the Expression option ON.
d. In the API Key field, enter the expression:
{{ $json["Enter your NASA API key"] }}. - Set Up the Form Trigger:
a. Add the
n8n Form Triggernode. b. Configure theformTitleto 'Test dynamic credentials'. c. Add aformFieldwithfieldLabel: 'Enter your NASA API key' and mark it asrequiredField. - Connect Nodes:
a. Connect the
n8n Form Triggerto theNASAnode. b. Connect theNASAnode to theRespond to Webhooknode. - Configure Respond to Webhook:
a. Set
respondWithto 'redirect'. b. In theredirectURLfield, enter={{ $json.url }}(or your desired redirect URL). - Obtain NASA API Key: Get a free API key from https://api.nasa.gov/.
- Test the Workflow: Execute the workflow and submit your NASA API key via the generated form.
