CallSource: Call Tracking & Source Attribution
CallSource: Call Tracking & Source Attribution ships as a ready-to-import n8n automation package: load the bundled workflow JSON, connect the credentials listed on this page, and activate it on self-hosted n8n or n8n Cloud.
Know which ad, campaign or sign made the phone ring — self-owned call tracking on your own Twilio numbers, with a daily calls-by-source report instead of a per-minute subscription.
- Tag every inbound call with the campaign that bought it, using one Twilio tracking number per source
- Forward each caller to your real line in seconds, with optional two-sided call recording
- Log every call to your own Google Sheet — number, source, campaign, caller, city and outcome
- Email a daily calls-by-source report with share of volume, unique callers and top campaigns
- Get an AI read on where the phone volume actually came from, plus one concrete next action
- Catch attribution gaps automatically: unmapped numbers and calls that had no destination are flagged
- Own the whole stack on Twilio pay-as-you-go instead of a per-number, per-minute call-tracking plan
Setup Service — optional live install and test. Choose your tier at checkout (not tied to this template's price).
Paste the license key from your receipt. It must match this template.
Workflow summary
2 coordinated workflows handle different parts of the automation.
Call Intake & Source Attribution
Required- 1A caller dials one of your Twilio tracking numbers and Twilio notifies the workflow
- 2The dialled number is matched against your Numbers sheet to find its source, campaign and destination
- 3The attributed call is written to your Calls sheet with caller, city, source and outcome
- 4The caller is forwarded to the real line straight away, with optional call recording
- 5Callers on an unmapped number still get through on your default line and are flagged in the log
Daily Calls-by-Source Digest
Optional- 1Runs every morning on a schedule in your timezone
- 2Reads yesterday's calls from the Calls sheet the intake workflow writes
- 3Groups them by source and campaign with call counts, share of volume and unique callers
- 4AI adds a one-line headline, a short read on the split and one recommended action
- 5Emails the report and records the day as sent so the same digest can never go out twice
