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/x-www-form-urlencoded" and Mapping Tamplate to convert it to JSON but still posting a binary data like an image file is missing I guess. Is there anything I'm missing ?
EDIT:
I have found another way:
I convert the image to base64 string then POST it as with content type "application/x-www-form-urlencoded". By this way I'm sending whole image as string. After I got the message I can convert it back to image in PHP. Only down side of this I could find is when I convert image to base64 its size gets a bit bigger. Other than that, I couldnt find any other downside. If there is could you please share with me ?

To upload a binary file (image) to an S3 bucket using API Gateway, you must activate binary support for your API Gateway REST API. To allow your API to access your S3 bucket, you must also create an AWS Identity and Access Management (IAM) role.
API Gateway can act as a passthrough, sending all data directly to a Lambda function. This makes it possible to send multipart/form-data to a lambda for processing.
Sign in to the API Gateway console at https://console.aws.amazon.com/apigateway . In the APIs navigation pane, choose the API you want to deploy. In the Resources navigation pane, choose Actions. From the Actions drop-down menu, choose Deploy API.

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!!
