Enabling Access Logging for API Requests and Responses

Introduction

In this guide, we will enable access logging for API requests and responses using Pulumi. This involves creating an API Gateway in AWS and configuring it to log requests and responses to CloudWatch Logs. AWS API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale.

Step-by-Step Explanation

Step 1: Create an API Gateway

First, we need to create an API Gateway. This will serve as the entry point for our API requests.

Step 2: Enable Access Logging

Next, we will configure the API Gateway to enable access logging. This involves setting up a CloudWatch Log Group and specifying the log format.

Step 3: Deploy the API

Finally, we will deploy the API so that it becomes accessible and starts logging requests and responses.

Summary

In this guide, we created an API Gateway and configured it to log requests and responses to CloudWatch Logs. This setup helps in monitoring and debugging API requests effectively.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create a CloudWatch Log Group
const logGroup = new aws.cloudwatch.LogGroup("api-gateway-log-group", {
    retentionInDays: 7, // Adjust the retention as needed
});

// Create an API Gateway Rest API
const api = new aws.apigateway.RestApi("my-api", {
    description: "API Gateway for logging requests and responses",
});

// Create a deployment for the API
const deployment = new aws.apigateway.Deployment("api-deployment", {
    restApi: api.id,
    stageName: "prod",
});

// Create a stage and enable access logging
const stage = new aws.apigateway.Stage("api-stage", {
    restApi: api.id,
    deployment: deployment.id,
    stageName: "prod",
    accessLogSettings: {
        destinationArn: logGroup.arn,
        format: JSON.stringify({
            requestId: "$context.requestId",
            ip: "$context.identity.sourceIp",
            caller: "$context.identity.caller",
            user: "$context.identity.user",
            requestTime: "$context.requestTime",
            httpMethod: "$context.httpMethod",
            resourcePath: "$context.resourcePath",
            status: "$context.status",
            protocol: "$context.protocol",
            responseLength: "$context.responseLength"
        }),
    },
});

export const apiUrl = pulumi.interpolate\`\${api.executionArn}/prod\`;
