I\'m trying to POST \"mutlipart\\form-data\" to my EC2 instance through AWS API Gateway, but I couldn\'t find a way to this. There is a way to post data using \"application/
Api Gateway team here.
Binary data isn't supported at the moment, but it's on our backlog. Several customers have requested this.
Some customers have had success using the base64 util in the mapping templates which may get it working for you: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html#util-template-reference
Other than that you'll have to wait for official support.
Edit
Binary support is finally here!!
