amazon web services - AWS: How to pass the resource defined in API gateway to lambda?

Question

I try to build a simple Rest API. I only know how to pass query strings to my lambda functions with mapping. Now I wonder whether there are ways to pass the "resource" to my lambda function?

For example, how can my lambda get "fruit" and "vegetable" please?

Answer 1

Integration Request LAMBDA will pass the request body alone to Lambda

Where as Integration Request LAMBDA_PROXY will attach headers, query params, etc and send enriched request similar to how it is here and request body will simply be as string within body. This already contains everything that we need, api-key used, api-id, headers, stages, parms, etc. if we don't like this, then we can customize the request body by setting a custom mapping template(like the other answer)

We can enable Lambda Proxy integration by clicking on Integration Request and checking on Use Lambda Proxy integration
