Aws Api Gateway Introduction Guide with Steps to Start with

Introduction to Aws Api Gateway

AWS API Gateway is a fully managed service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. It is a powerful tool that can be used to create APIs for web applications, mobile applications, and backend services.

With AWS API Gateway, developers can easily create APIs that integrate with AWS services like AWS Lambda, Amazon S3, and Amazon DynamoDB, as well as third-party services like Salesforce, Twilio, and Stripe. API Gateway provides a scalable and secure platform for building APIs that can handle any amount of traffic.

In this article, we will explore how to build an API request on AWS Cloud using API Gateway.

Getting Started with AWS API Gateway

To get started with AWS API Gateway, you need to create an API in the AWS Management Console. You can do this by following these steps:

Open the AWS Management Console and navigate to the API Gateway service.

  1. Click the "Create API" button.
  2. Select the "REST API" option and click the "Build" button.
  3. Choose "New API" and give your API a name and description.
  4. Select the "Edge optimized" endpoint type.
  5. Click the "Create API" button.

Creating a Resource and Method

Now that you have created an API, you can add resources and methods to it. A resource represents a collection of related API endpoints, while a method represents an HTTP verb (such as GET, POST, PUT, or DELETE) that can be used to access a resource.

To create a resource and method, follow these steps:

  • Click the "Create Resource" button in the API Gateway console.
  • Enter a name for your resource and click the "Create Resource" button.
  • Select the resource you just created and click the "Create Method" button.
  • Select the HTTP method you want to use (such as GET or POST) and click the checkmark button.
  • In the "Integration Type" section, select "Lambda Function" and choose the Lambda function you want to use for your API.
  • Click the "Save" button .

Deploying Your API

Before you can start using your API, you need to deploy it. To do this, follow these steps:

In the API Gateway console, select your API.

Click the "Actions" button and select "Deploy API".

Choose the deployment stage you want to use (such as "prod" or "test") and click the "Deploy" button.

Your API is now deployed and ready to use.

Making an API Request

To make an API request, you can use a tool like Postman or cURL. Here's an example cURL command to make a GET request to your API:

curl -X GET https://.execute-api..amazonaws.com//
Replace with your API ID, with your AWS region, with your deployment stage, and with the name of the resource you created.

Conclusion

AWS API Gateway is a powerful tool for building APIs in the cloud. With its ease of use and integration with other AWS services, it is a great choice for developers who want to create scalable and secure APIs. By following the steps outlined in this article, you can quickly create an API and start making requests to it.
