Serverless Backend with AWS Lambda & API Gateway · Lesson

Request/Response Transformations

Customize API Gateway's request and response payloads using mapping templates (VTL) to integrate with diverse backend systems.

Bridging the Data Gap

Imagine your API clients speak one data language, but your backend service understands another. How do you make them communicate smoothly?

API Gateway's request and response transformations act as a universal translator, modifying payloads to ensure compatibility between different systems.

Introducing Mapping Templates

At the heart of transformations are mapping templates. These are text-based templates written using the Velocity Template Language (VTL).

You define a VTL template that tells API Gateway exactly how to restructure or modify the incoming (request) or outgoing (response) data.
