What this card says
Why do we need it?
Status codes tell clients what “success” means. Wrong codes confuse frontend retries.
What is it?
201 Created = resource finished. 202 Accepted = request accepted for processing that is not done yet.
How to do it
Intake Lambda returns statusCode 202 and a body with orderId; worker creates the DynamoDB row asynchronously.
statusCode: 202
Example
Mobile app shows “Order received” immediately from 202, then polls GET /orders/{id} when you add it later.
