Add Snap Lead Form Submission metrics to Snapchat connector#1691

The Snapchat connector is missing native Lead Form Submission metrics. Campaigns optimized for LEAD_FORM_SUBMISSIONS read zero in our reports because the connector only exposes pixel/CAPI conversion events (conversion_sign_ups, custom_event_*), not on-platform lead forms.

Example: one of our ad accounts has 15+ ad squads with ad_squad_optimization_goal = LEAD_FORM_SUBMISSIONS and ~$17K spend over 2 years, all showing 0 attributed conversions in Windsor — while Snap Ads Manager shows the actual lead totals natively.

Snap’s Marketing API exposes these stat fields. Please add to the connector:

• lead_form_submissions
• total_lead_form_submissions
• cost_per_lead_form_submission
• lead_form_submission_rate

Related to #971 (Snapchat Connector Needs More Metrics) but scoped to named fields.

Is this on the roadmap or available in beta? What’s the typical turnaround?

Good news: this is already available. The Snapchat connector exposes the field Native Leads (id: native_leads), which counts Snapchatters who swipe up, complete the required fields, and hit Submit on an on-Snapchat Lead Form attachment. This is the native Lead Form Submission metric for LEAD_FORM_SUBMISSIONS-optimized campaigns, and it is separate from the pixel/CAPI conversion events (such as Conversion Sign Ups / conversion_sign_ups). Add the Native Leads field to your query (alongside campaign or ad dimensions and Date as needed) and your lead-form-optimized campaigns will report their submissions.
