APIGatewayEventbusParadigma

APIGatewayEvent is a data structure used in AWS Lambda functions to handle HTTP requests and responses. It is automatically generated by Amazon API Gateway when an HTTP request is made to an API. The APIGatewayEvent object contains information about the request, such as the HTTP method, headers, query string parameters, and the request body. This data can be accessed within the Lambda function to process the request and generate an appropriate response.

The APIGatewayEvent object includes several key properties:

- resource: The resource path of the API request.

- path: The full path of the API request.

- httpMethod: The HTTP method used for the request (e.g., GET, POST, PUT, DELETE).

- headers: A dictionary of HTTP headers included in the request.

- queryStringParameters: A dictionary of query string parameters included in the request.

- pathParameters: A dictionary of path parameters included in the request.

- stageVariables: A dictionary of stage variables included in the request.

- requestContext: An object containing information about the request context, such as the request ID, account ID, and API ID.

- body: The request body, if any, as a string.

- isBase64Encoded: A boolean indicating whether the request body is Base64-encoded.

The APIGatewayEvent object is used in conjunction with the APIGatewayProxyResult object to handle the response. The APIGatewayProxyResult object contains information about the response, such as the status code, headers, and the response body. The Lambda function can generate an APIGatewayProxyResult object based on the processed request and return it to API Gateway, which will then send the response back to the client.

APIGatewayEvent and APIGatewayProxyResult are integral to building serverless applications using AWS Lambda and API Gateway, enabling developers to create scalable and efficient APIs without managing servers.
