API gateway dynamic xml json response

Hi,

Please suggest what integration response and method response configuration is required.

It is highly dependent on your backend implementation and it is difficult to get a correct answer without the knowledge of your architecture and requirements. If your backend is HTTP, there is a HTTP proxy integration and HTTP non-proxy integration (a.k.a. custom integration). If your backend is Lambda, there are Lambda proxy integration, and Lambda non-proxy integration. If your backend is one of AWS services (e.g., SQS, Step Functions), then use AWS integration. You can find some insights from those tutorial.

Again, which integration response and method response should be configured is based on which integration type you choose, which is highly dependent on your architecture and requirements.
