Integrate API methods with Lambda functions

In this section, we’ll connect our REST API endpoints to their corresponding Lambda functions. This integration will enable our API Gateway to trigger the appropriate Lambda functions based on the HTTP methods and routes. We’ll cover the following integrations:

API Resource - MethodLambda FunctionDescription
/users GETlist-usersRetrieve all users from the system
/users POSTcreate-userAdd a new user to the system
/users/{userId} GETget-userRetrieve details of a specific user
/users/{userId} PATCHupdate-userModify an existing user’s information
/users/{userId} DELETEdelete-userRemove a user from the system

Each integration will be configured with the appropriate request/response mappings to ensure seamless communication between API Gateway and Lambda functions.
