API Gateway Mapping Template missing toJson

0

API Gateway seems to have limited VTL support, and in particular 2 key features are missing that AppSync VTL does support - $util.toJson and #return. Are these on the roadmap or are there workarounds? I know I can always fall back to Lambda, but I'm specifically trying to do as much in the mapping template as possible.

Thank you for the feedback. We have a Feature request to add same utils functions that are available for AppSync in the API Gateway VTL https://docs.aws.amazon.com/appsync/latest/devguide/resolver-util-reference.html

I have added your voice to the feature request. Apologies for the delayed acknowledgement.

    Hi! After hours of trial and error'ing I also found out that $util.toJson() was not actually working in API Gateway response templating. All guides I've found are always bound to AppSync, hence I assumed that those two used the same engine. Do you have any documentation on what is actually supported in API Gateway regarding VTL?
