Question

A company wants to use an API to translate text from one language to another. The API must receive an HTTP header value and pass the value to an embedded library. The API translates documents in 6 minutes. The API requires a custom authorization mechanism. What should a solutions architect do to meet these requirements?

Accepted Answer

Option A satisfies every requirement:

1. **HTTP Header Access**: API Gateway REST API with `AWS_PROXY` (Lambda Proxy) integration passes the **entire HTTP request** — including all headers, query strings, body, and path parameters — directly to the Lambda function as a structured event object. The Lambda function can then extract the specific header value and pass it to the embedded translation library.

2. **Embedded Library Support**: Lambda functions can package custom libraries (up to 250 MB unzipped with layers, or 10 GB with container images). The translation library can be embedded directly in the Lambda deployment package.

3. **6-Minute Processing Time**: Lambda supports a **maximum timeout of 15 minutes**. A 6-minute translation task fits comfortably within this limit. API Gatew
