WildJar + HubSpot + Zapier Integration: Automate Google Ads Call Lead Attribution

My client is an Australian solar energy company (Smart Energy Answers) looking for an experienced HubSpot/automation specialist to implement an end-to-end call lead integration between WildJar (our call tracking platform), HubSpot (our CRM), and Zapier. THE PROBLEM: We generate 85-300+ phone call leads per month from Google Ads, tracked via WildJar. However, these call leads aren't being automatically created or attributed in HubSpot, so our sales team manually enters them - and the "Google Ads" source attribution gets lost. This means our HubSpot funnel reporting undercounts our Google Ads performance every month. THE SOLUTION (we have a detailed implementation guide ready to hand over): 1. Configure WildJar's native HubSpot integration, scoped to our Google Ads tracking number pools only, so call leads auto-create as contacts in HubSpot (matched/deduplicated on phone number) 2. Build a HubSpot workflow + custom "Call Lead Source" property that stamps proper Google Ads attribution on these contacts (the native integration only embeds source in the contact name, which isn't reportable) 3. Set up lead routing/contact owner assignment and internal notifications to sales 4. Build a Zapier automation (WildJar "New Phone Call" trigger → HubSpot Create/Update Contact) to map rich call data into custom properties: tracking source, call duration, new vs repeat caller, recording link - including phone number formatting to E.164 to prevent duplicate contacts 5. Establish deduplication safeguards and document the sales-side merge process 6. Run through our testing checklist (new caller test, repeat caller test, merge simulation, attribution reporting reconciliation against WildJar's dashboard) DELIVERABLES: - Working, tested integration across all three platforms - All workflows, properties, and Zaps documented - A short handover note covering what was built and how to maintain/roll back WHAT WE PROVIDE: - Admin access to WildJar, HubSpot, and Zapier - A step-by-step implementation guide we've already prepared (you'll validate and execute it, flagging anything that needs adjusting) - Quick turnaround on questions/approvals
