You want to create a REST API with a resource /users that supports GET and POST methods. You start with MOCK integration for both methods to test. Later, you want GET to fetch data from a Lambda function and POST to store data in DynamoDB via Lambda. What is the best approach to achieve this?
ACreate the API with MOCK integration first, then update GET and POST methods to use Lambda integration with proper permissions.
BCreate separate APIs for MOCK and Lambda integrations and switch clients between them.
CUse MOCK integration permanently because it is simpler and faster.
DDirectly connect POST method to DynamoDB without Lambda and keep GET as MOCK.
Step-by-Step Solution
Solution:
Step 1: Start with MOCK integration for testing
MOCK lets you test API behavior without backend, a good first step.
Step 2: Update methods to Lambda integration
Later, replace MOCK with Lambda integration for GET and POST to connect real backend logic.
Step 3: Ensure permissions and backend setup
Configure Lambda permissions and DynamoDB access properly for smooth operation.
Final Answer:
Create the API with MOCK integration first, then update GET and POST methods to use Lambda integration with proper permissions. -> Option A
Quick Check:
Start MOCK, then switch to Lambda integration [OK]
Quick Trick:Test with MOCK, then switch methods to Lambda integration [OK]
Common Mistakes:
Trying to use MOCK and Lambda in separate APIs
Keeping MOCK integration permanently
Connecting POST directly to DynamoDB without Lambda
