+When using API Gateway HTTP API to front your Lambda functions, you can instruct `ApiGatewayResolver` to conform with their contract via `proxy_type` param:

+
+	```python hl_lines="3 7"
+	from aws_lambda_powertools import Logger, Tracer
+	from aws_lambda_powertools.logging import correlation_paths
