Building a REST API with AWS Gateway and Python

AWS Gateway is a powerful tool for building APIs that scale to meet the demands of modern web and mobile applications. With AWS Gateway, you can create RESTful APIs that expose your data and business logic to developers who can then build rich, interactive applications that consume your API.

REST API is an industry standard for building scalable, distributed web applications. With AWS Gateway, you can easily build a REST API that supports both GET and POST methods, as well as complex query parameters. You can also add support for other HTTP methods, such as PUT, DELETE, and HEAD.

Using AWS Gateway, you can quickly create APIs that are secure and robust. You can also use it to deploy your code to a production environment with minimal effort. Additionally, AWS Gateway allows for seamless integration with other AWS services, such as S3 and DynamoDB, enabling you to easily add complex functionality to your APIs.

Before building a RESTful API with AWS Gateway, you should have the following in place:

-Select Node from the Runtime Dropdown.

When the function is called, it first determines the HTTP method of the request from the event object. Then it handles the request accordingly:

Deploy the API by clicking on “Actions” and selecting “Deploy API”.

Select a deployment stage (e.g. “prod” or “test”) and click on “Deploy”. Use the generated API endpoint to make requests to your API.

Now, our API is up and running. You can send a test HTTP request through Postman. By sending a request to your invoke URL, you should see a 200 OK status code. For this test, no request body is needed for the incoming request.
