Freelancers using JustcallFreelancers using JustcallZapier said it couldn't be done — so I built around it.
A recruitment agency was manually logging every call outcome into Less Annoying CRM after each JustCall conversation. Zapier's own triggers ("Call Updated" and "Call Completed") fire as two separate events and can't be linked by Call ID — so the automation everyone assumed was simple turned out to be technically impossible with default, off-the-shelf tools.
I diagnosed the exact limitation inside JustCall's Zapier integration, then engineered a custom event-correlation layer that captures both triggers, matches them reliably via the JustCall REST API, and pushes clean, accurate updates straight into the correct pipeline stage in LACRM — with a parallel sync to Google Sheets for reporting.
Result: zero manual data entry, real-time CRM records the sales team could finally trust, and full documentation so their internal team can maintain the system without ongoing developer support.
This is the kind of API integration and workflow debugging I do daily — across Make, n8n, Zapier, Python, and REST API/webhook architecture. If your CRM, telephony, or sales tools aren't talking to each other properly, let's fix that.::
