Native Google Ads GCLID Capture & Offline Conversion Upload for WhatsApp Journeys
M
Muhamad Irfan From SleekFlow
When users click a Google Ad and land on a webpage before entering WhatsApp, the Google Click ID (GCLID) is lost the moment they enter the messaging channel. SleekFlow's current workaround, injecting a ref ID into the pre-filled WhatsApp message, fails in 80–90% of cases because users edit or delete the pre-filled text before sending. This makes it impossible to close the attribution loop between Google Ads spend and WhatsApp-generated leads natively within SleekFlow.
Requested Capabilities
- GCLID / UTM parameter pass-through; a mechanism (e.g., a tracking script snippet, or a dedicated landing page widget) that captures gclid, gbraid, wbraid, and UTM parameters from the originating Google Ads click and associates them with the resulting WhatsApp conversation, independent of pre-filled message content.
- Native "Google Ads Click ID" contact property; a system contact property (gclid) that is auto-populated when a conversation originates from a tracked Google Ads click, analogous to how SleekFlow already surfaces utm_source / utm_medium or CTWA metadata for Meta Ads.
- Google Ads Offline Conversion Upload action in Flow Builder; a native Flow Builder action node (similar to the existing webhook action) that calls the Google Ads UploadClickConversions API when a conversion event occurs (e.g., contact label updated, lead status changed), sending the stored gclid + hashed phone number directly to Google Ads, without requiring a third-party middleware such as Make.com or n8n.
Business Impact / Use Cases
• Businesses running Google Search, Display, or Performance Max campaigns that drive leads into WhatsApp cannot measure campaign-level ROI (cost-per-lead by campaign / ad group / keyword) without this capability.
• This is a known gap affecting customers across multiple regions (UAE, Brazil confirmed). The current workaround requires a custom server-side attribution database + middleware layer, which is infeasible for most customers without dedicated engineering resources.
• Closing this gap would make SleekFlow competitive with dedicated CTWA attribution tools (e.g., WAct; https://www.waconversiontracking.com/) for Google Ads, not just Meta Ads.
