Getting return responses from AWS Lambda functions is quite straightforward. To help you get started, here are the steps you need to take:
Configure your Lambda function to return a response:
In your Lambda function code, include a return response that can be used as a callback in your API gateway. You should use a JSON format to make sure the response can work with any other language.
Create an API Gateway that is connected to the Lambda function:
In the AWS Console, create an API Gateway for your Lambda function. After that, configure it to trigger the Lambda function with a POST request whenever an API invocation is called. You can also add authentication tokens and other authorization functions to the API Gateway configuration.
Test the API Gateway and Lambda function:
Once you have configured both the API Gateway and the Lambda function, you can now test them to see if the return response is properly configured. To do so, go to the API Gateway console, check the integration responses, and make sure they are set up correctly.
Deploy the API Gateway and Lambda function:
After you have tested everything, you can now deploy the API Gateway and Lambda functions. Simply select the Deploy API option from the API Gateway console, choose a stage, and then confirm the deployment. After that, the Return Response from your Lambda function should be available for use.
By following these steps, you should be able to get the Return Response from your AWS Lambda functions. If you have any questions or need more assistance, feel free to take a look at the official AWS documentation for more information.
Hope this helps!
