How UID and GCLID are Matched
Learn how WAConversionTracking matches the unique user ID with the Google Ads click ID for accurate lead attribution.
How UID and GCLID Are Matched
WAConversionTracking uses both the GCLID and a unique UID to tie each WhatsApp message back to its originating Google Ads click.
🧩 Breakdown:
- When a user visits your site via a Google Ad, the
gclidand UTM data is captured by our script.
- When the WhatsApp button is clicked the following occurs:
- A UID is generated and sent to our database and attached to the preset WhatsApp message.
- GCLID & UTM Parameters are captured and sent to our data base
- When the user send the preset message by WhatsApp WAConversionTracking receives the UID from the message body.
- The system checks its records and matches the UID to the stored GCLID from the same session and marks the button click as a conversion.
✅ If both values are found:
→ The match is confirmed, and a valid lead is recorded.
→ The lead is then sent to your connected Google Sheet and optionally to Google Ads.
🛠 How to Ensure This Works
- Always use the WAConversionTracking button or script so UID is inserted
- Do not allow WhatsApp messages to be manually edited by users (UID could be deleted)
- Ensure the script is present on landing pages receiving Google Ads traffic
