API Gateway Integration
What is API Gateway Integration?
API Gateway Integration is a feature offered by AWS (Amazon Web Services) that allows developers to connect AWS services and non-AWS services. This makes it easier to initiate asynchronous, batch and one-time integration requests.
Why is it important?
API Gateway Integration simplifies the process of linking different services and resources, making your applications more flexible and scalable. It also manages the security and management aspects, so you can focus on building your application.
How does it work?
API Gateway Integration works by exposing HTTP and WebSocket APIs. These APIs can interact with AWS services like Lambda and DynamoDB, or with other web applications. You configure an API Gateway as a series of resources and methods. These methods are then tied to integrations, which define the details of the request-response flow between the API and the backend service.
Exam Tips: Answering Questions on API Gateway Integration
Understanding the integration types and the role of an integration request or integration response in the API Gateway is crucial for the exam. Remember to revise:
• Integration types - AWS, HTTP, Mock, VPC Link, and AWS Service
• The role of data mapping templates and mapping templates languages.
Pay special attention to error handling, throttling, and caching as they commonly appear in exam questions.
Having a clear and practical understanding of API Gateway integration will definitely increase your chances of passing the exam.

API Gateway Integration practice test
API Gateway supports different types of integrations with back-end systems, such as AWS Lambda, AWS Service proxies, or HTTP proxies. This allows API Gateway to connect with various services to process incoming requests and respond accordingly. For example, a Lambda integration allows API Gateway to invoke a Lambda function when a request is made. The Lambda function then processes the request and generates a response, which is sent back to the client via API Gateway. Similarly, HTTP proxy integration allows API Gateway to forward an incoming request to an HTTP or HTTPS endpoint, while AWS service proxy integration enables the integration of API Gateway with other AWS services.
