crossdomain.xml goes on the server where the data is accessed. It doesn't matter if its on your site or not, because the external site has to decide if it wants to give access not you.

everytime i run my api., it will look for a crossdomain.xml (https://emerchantdev.com.my/crossdomain.xml) but its not avialable, and i don't think that they put that file in their server just for my request.

is there anyway to bypass this one?

You could build a script in PHP or your favorite language on your server that you could connect to which would serve as a proxy connecting to the other server.
