Quick Patterns

Get current subscriber info in email

var email = Platform.Variable.GetValue("@_emailaddr")
         || Platform.Variable.GetValue("@emailaddr");
var subKey = Platform.Variable.GetValue("@_subscriberkey")
          || Platform.Variable.GetValue("@subscriberKey");

Redirect to login if no session

var session = Platform.Request.GetCookieValue("session");
if (!session) {
    Platform.Response.Redirect("/login?next="
        + Platform.Function.URLEncode(Platform.Request.GetResolvedURL()));
}

JSON API response boilerplate

Platform.Response.SetContentType("application/json");
var method = Platform.Request.Method;
if (method !== "POST") {
    Platform.Response.SetResponseCode(405, "Method Not Allowed");
    Write(Stringify({ error: "POST required" }));
    return;
}
var body = Platform.Function.ParseJSON(Platform.Request.GetPostData() + "");
