I have an created a REST application in nodejs and also I have configured API gateway for the URLs. I have a URL with query parameters. When one request from postman with query params with special characters like +,\ , then I need to encode these from API gateway. Is it possible to do that? Someone please help with an answer... Thanks in advance

We need to override the query parameter in mapping template of IntegrationRequest, function we need in vtl is $util.urlEncode.
The moment we start overriding, we need to ensure to build entire request body, parameters, etc.
Template from here, i just added one additional function $util.urlEncode call to encode parameters. If query parameter value is Test4! it will be changed to Test4%21
#set($allParams = $input.params())
{
"params" : {
#foreach($type in $allParams.keySet())
#set($params = $allParams.get($type))
"$type" : {
#foreach($paramName in $params.keySet())
"$paramName" : "$util.escapeJavaScript($util.urlEncode($params.get($paramName)))"
#if($foreach.hasNext),#end
#end
}
#if($foreach.hasNext),#end
#end
}
}
