How do I access a POST parameter in Node js AWS Lambda with API Gateway integration?

Question

I know how to access GET string variables in a Node js Lambda that is integrated with API Gateway with:

 event["queryStringParameters"]["variable_name"]

What is the equivalent for accessing POST variables?

Answer 1

Use the following

if (event.body !== null && event.body !== undefined) {
        let body = JSON.parse(event.body) //use in case of JSON body
        //your code
}
