How to set default Lambda Authorizer for API Gateway

Question

API Gateway has multiple Lambda Authorizer.
I want to set Lambda Authorizer for all Resources(Methods)
For that I need to configure Lambda Authorizer for all methods. Is there any configuration which we can do at the global level and applied for all the methods in the API Gateway.
This is very helpful when I have 1000s of methods in API Gateway.

Answer

How are you creating the API Gateway? If you use Serverless Application Model you can define the default parameters for each method (including authentication). At deployment time, it's done for you. There are other defaults too such as the Lambda function language - many more...

From the documentation check out Api (for REST APIs) and HttpApi (for HTTP APIs). Both have an Auth section that lets you specify the default Lambda Authorizer but it can be overriden on a method-by-method basis.
