Passing parameter in Meteor.call Using postman

Hi every one !. i had a methods like this.
Meteor.methods({
“test.api”: function (param1, param2) {
console.log(“param1, param2”, param1, param2);
return param1 + param2;
}
});
i call this methods from postman but i dont know how to pass to param1 and param2.
Are there any way to pass to this params in a Meteor.call on client ? Android or ios ?
thanks for your time.
