- 🔸API Gateway doesn’t support multi-region deployments for high availability. It is a service that is deployed in a single region but comes with a global endpoint that is served from AWS edge locations (similar to a CloudFront distribution). You cannot have multiple API Gateways with the same hostname in different AWS regions and use Route 53 to distribute the traffic. More in [this forum post](https://forums.aws.amazon.com/thread.jspa?messageID=735342&#735342).
- 🔸Integration timeout: All of the various integration types (eg: Lambda, HTTP) for API Gateway have timeouts, as described [here](http://docs.aws.amazon.com/apigateway/latest/developerguide/limits.html#api-gateway-limits). Unlike some limits, these timeouts can't be increased.
- 🔸API Gateway returns a 504 status code for any network or low level transport related issue. When this happens, you may see a message in the CloudWatch logs for the request that includes the message: `Execution failed due to an internal error`. One possible reason for this error is that even though your backend server is up and running, it may be doing something outside of the HTTP specification (like not sending well-formed chunked messages). You can test by hitting your backend directly with the `curl --raw -S -i <backend-endpoint-url>` and seeing if it complains.
- 🔸API Gateway does not support gzip compression of responses. See [AWS forum](https://forums.aws.amazon.com/thread.jspa?threadID=192948).
- 🔸AWS X-Ray support exists but cumbersome to use. If you have other AWS services calling API Gateway, your trace will seemingly end there. API Gateway will also not appear as a node in your service map. [More here](http://docs.aws.amazon.com/xray/latest/devguide/xray-services-apigateway.html).
- 🔸Be careful using the export feature. The resulting Swagger template is often incomplete and doesn't integrate well with the Swagger extensions for things such as CORS.
- 🔸Many changes to API Gateway resources need to be 'deployed' via console or API call. Unfortunately, API Gateway is terrible about notifying the user when changes are staged for deployment and what changes require deployment. If you've changed something about your API and it's not taking effect, there's a decent chance you just need to deploy it.
