Aws Api Gateway Api Key Generator
Step 1 of Amazon API Gateway Tutorial. Navigate to the AWS IAM Console. Click on Roles in the left menu, and then click the Create New Role button. Name the role APIGatewayLambdaExecRole and click Next Step. Select the Role Type. Under AWS Service Roles, select AWS Lambda. On the Attach Policy screen, skip this step by clicking Next Step.At this point, review the information you provided.
- Creating an AWS Service Proxy for Amazon SQS Want to use SQS without AWS Lambda functions? Get ready to dive into API Gateway so you can send and receive messages while securing them with IAM roles.
- Cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by -generate-cli-skeleton.If other arguments are provided on the command line, the CLI values will override the JSON-provided values.
Use terraform to quickly setup your own Short URL generator using a custom domain with AWS API Gateway, CloudFront, Lambda, Route 53 and S3.
Approach
The plan is to use CloudFront to cache redirecting web pages at the edge of the CloudFront network that will redirect form the short URL to the full URL.
The redirecting web pages will be served up from S3. With S3 you can create an object with a meta data entry called Website Redirect Location. When an S3 bucket is configured to host a static website objects ( with a Website Redirect Location metadata entry) will be served up over HTTP as a redirecting webpage.
API Gateway and AWS Lambda will be used to create and delete shortlinks via HTTP API calls. The API will be protected with an API key, and will be served up via the same CloudFront distrubtion.
Finally Route 53 will alias the custom domain name to the domain name of the CloudFront distribution.
Api Key Steam
Prerequisites
Setup the domain that you want to use for your short URLs as a Hosted Zone in Route 53. Teamviewer 9 license key generator free. Details of how to do this can be found here.
Deploy
Initialise the backend to use an S3 bucket to store the state (this only needs to be done once):
Alternatively you can remove terraform.tf which defines the backend store - this will cause terraform to default to local file storage.
Use terraform to apply the infrastructure change needed to run this short URL generator:
You'll be prompted for:
- The short URL domain you want to use (e.g.
example.com) - Your AWS account number
Once the infrastrucutre has been created it will be given an output similar to the following:
Using the API
Deploying the infrastructure with terraform will take only a few minutes and once the CloudFront distribution has been fully initialised you'll be ready to start creating URLs.
Creating a Short URL
Creating a URL is done with a POST request to the /admin endpoint. The x-api-key header should be set to the Admin API Key value that was generated in the output of the terraform setup:
The response will provide you with the full short URL and token value in JSON output:

So here's an example of one of my short URL: https://jmsr.io/cwM1iQ. This link is a short link to my Build your own custom Short URL generator using AWS blog post.
CloudFront serves up the empty S3 object as shown below using CURL with the vebose flag. You get a 301 Moved Permanently response with the Location header set to the full URL.
Deleting a Short URL
Deleting an endpoint is also done via a DELETE request to /admin/<token>, for example:
Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. APIs act as the 'front door' for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications.
API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, CORS support, authorization and access control, throttling, monitoring, and API version management. API Gateway has no minimum fees or startup costs. You pay for the API calls you receive and the amount of data transferred out and, with the API Gateway tiered pricing model, you can reduce your cost as your API usage scales.
API Types
RESTful APIs
Build RESTful APIs optimized for serverless workloads and HTTP backends using HTTP APIs. HTTP APIs are the best choice for building APIs that only require API proxy functionality. If your APIs require API proxy functionality and API management features in a single solution, API Gateway also offers REST APIs.
WEBSOCKET APIs
Build real-time two-way communication applications, such as chat apps and streaming dashboards, with WebSocket APIs. API Gateway maintains a persistent connection to handle message transfer between your backend service and your clients.
Benefits
Efficient API development
Run multiple versions of the same API simultaneously with API Gateway, allowing you to quickly iterate, test, and release new versions. You pay for calls made to your APIs and data transfer out and there are no minimum fees or upfront commitments.
Performance at any scale
Provide end users with the lowest possible latency for API requests and responses by taking advantage of our global network of edge locations using Amazon CloudFront. Throttle traffic and authorize API calls to ensure that backend operations withstand traffic spikes and backend systems are not unnecessarily called.
Cost savings at scale
API Gateway provides a tiered pricing model for API requests. With an API Requests price as low as $0.90 per million requests at the highest tier, you can decrease your costs as your API usage increases per region across your AWS accounts.
Easy monitoring
Monitor performance metrics and information on API calls, data latency, and error rates from the API Gateway dashboard, which allows you to visually monitor calls to your services using Amazon CloudWatch.
Flexible security controls
Authorize access to your APIs with AWS Identity and Access Management (IAM) and Amazon Cognito. If you use OAuth tokens, API Gateway offers native OIDC and OAuth2 support. To support custom authorization requirements, you can execute a Lambda authorizer from AWS Lambda.
RESTful API options
Create RESTful APIs using HTTP APIs or REST APIs. HTTP APIs are the best way to build APIs for a majority of use cases—they're up to 71% cheaper than REST APIs. If your use case requires API proxy functionality and management features in a single solution, you can use REST APIs.
