On load, reads gclid + utm_* from the URL and stores them in a * first-party cookie for 90 days (only overwrites gclid when a new one * is present, so a later organic visit does not wipe the paid click). * 2. Appends those params to every calendly.com link and to any inline * Calendly embed, so a completed booking carries them into Calendly and * onward to the RedRain integration. */ (function () { 'use strict'; var COOKIE = 'jm_attr'; var MAXAGE = 60 * 60 * 24 * 90; // 90 days var UTM_KEYS = ['utm_source', 'utm_medium', 'utm_campaign', 'utm_content', 'utm_term']; function readCookie(name) { var m = document.cookie.match('(?:^|; )' + name + '=([^;]*)'); return m ? decodeURIComponent(m[1]) : ''; } function writeCookie(name, val) { document.cookie = name + '=' + encodeURIComponent(val) + '; path=/; max-age=' + MAXAGE + '; SameSite=Lax; Secure'; } // ---- 1. capture from URL, merge with stored ---- function capture() { var url = new URLSearchParams(window.location.search); var stored = {}; try { stored = JSON.parse(readCookie(COOKIE) || '{}'); } catch (e) { stored = {}; } var incomingGclid = url.get('gclid'); if (incomingGclid) { stored.gclid = incomingGclid; } // only overwrite on a fresh click UTM_KEYS.forEach(function (k) { var v = url.get(k); if (v) { stored[k] = v; } }); // if a gclid arrived but no utm_source, tag the source so RedRain is not blank if (incomingGclid && !stored.utm_source) { stored.utm_source = 'google'; stored.utm_medium = 'cpc'; } if (Object.keys(stored).length) { writeCookie(COOKIE, JSON.stringify(stored)); } return stored; } var attr = capture(); if (!attr || (!attr.gclid && !attr.utm_source)) { return; } // nothing to forward // ---- 2. build a query string for Calendly ---- function calendlyParams() { var p = new URLSearchParams(); UTM_KEYS.forEach(function (k) { if (attr[k]) { p.set(k, attr[k]); } }); // carry the raw gclid too. utm_content is the safe carrier RedRain can map // if its Calendly field mapping does not expose a native gclid slot. if (attr.gclid) { p.set('gclid', attr.gclid); if (!p.get('utm_content')) { p.set('utm_content', 'gclid:' + attr.gclid); } } return p.toString(); } function withParams(href) { if (!href || href.indexOf('calendly.com') === -1) { return href; } var qs = calendlyParams(); if (!qs) { return href; } // don't double-append if (href.indexOf('utm_source=') !== -1 || href.indexOf('gclid=') !== -1) { return href; } return href + (href.indexOf('?') === -1 ?
