With an AUTHORIZER source, API keys are returned by a Lambda authorizer as part of the authorization response. This method involves using a Lambda function to authenticate and authorize requests. This approach is often used when there’s a need for more robust security measures, as it adds an additional layer of protection by requiring function execution for access.
Which Source Should You Choose?
The choice between HEADER and AUTHORIZER depends on your specific needs and considerations. If simplicity and ease of implementation are your primary concerns, sourcing from HEADER could be the better choice. However, if your project requires advanced security measures, or if your application has a complex authorization process, sourcing from AUTHORIZER could provide the additional protection and control you need.
Key Considerations When Choosing Your Source
- Security Needs: If your API handles sensitive data, you may want to choose the AUTHORIZER source for its added security.
- Complexity of Authorization Process: For applications with multi-tiered user roles and access levels, an AUTHORIZER source can provide the flexibility needed.
- Ease of Implementation: If you prefer a straightforward method that’s easy to implement, a HEADER source could be the better choice.
Expert Advice for Choosing the Right Source
According to AWS documentation, both HEADER and AUTHORIZER sources have their advantages. The HEADER method is praised for its simplicity and ease of use, while the AUTHORIZER method is lauded for its added layer of security. Therefore, it’s crucial to assess your specific requirements before deciding on your API key source.
