Integration of CRM through Google Sheets and Measurement Protocol

Goal: To link offline leads with traffic sources in GA4 without implementing an expensive CRM system.
Solution: A custom JavaScript "form listener" has been developed that collects user data in Session Storage.
Technical setup: A script has been configured for the automatic transfer of parameters (Client ID, Session ID, gclid, fbc) to a secure Google Sheet via Webhook.
Measurement Protocol: A mechanism has been implemented to send data about closed deals from the sheet directly to GA4 and Google Ads for campaign optimization.

Result:
A free mini-CRM has been created with complete tracking of advertising sources.
End-to-end analytics: now every offline sale is automatically linked to a specific advertising campaign.
Data accuracy: 100% match of offline conversions to traffic sources.
