Why is Pinterest click-ID coverage already working before native ships?

Per GL#361, the Admaxxer pixel captures 12 click-IDs on every visitor_payments row at payment time — including epik. So every Pinterest promoted-pin click that converts in the next 90 days carries the click-ID back to the order row. Native integration adds the spend side; revenue-side attribution is already at full fidelity.

Can I forward Admaxxer revenue back to Pinterest's CAPI?

Once native lands, yes — Admaxxer will forward server-side conversion events to Pinterest's Conversions API the same way we do for Meta and Google today (improving Pinterest's optimization layer's match rate). For now, ensure the Pinterest pixel is firing alongside Admaxxer's pixel for browser-side conversions.

Do I need to UTM-tag organic pin clicks?

No. Organic pinterest.com referrers are auto-classified by the 30-platform classifier as utm_source=pinterest&utm_medium=social. UTMs are only needed if you want per-board or per-creator campaign-level attribution beyond the platform-level classification.

When will native Pinterest Ads land?

Active development. The auth path is paste-token (refresh token from the Pinterest Developer Portal), matching Meta + Google. Star the integration on /integrations to be notified.

Pinterest Ads integration — coming soon

Native API integration for Pinterest Ads is in active development. Until then, you can attribute every Pinterest Ads dollar today with a two-step UTM-and-pixel bridge: tag your Pinterest Ads URLs with the UTM template below, paste the Admaxxer pixel on your storefront, and our 30-platform smart-referrer classifier (per GL#361) auto-attributes revenue with 365-day first-touch persistence.

The bridge — use our pixel + UTM tagging today

Three steps. About five minutes total.

Step 1 — Install the Admaxxer pixel

If you haven't already, drop the Admaxxer pixel into your storefront's <head>. Works on Shopify, WooCommerce, BigCommerce, Squarespace, Wix, Webflow, and any custom storefront. See install instructions for 35+ platforms.

Step 2 — Tag every Pinterest Ads URL with UTMs

In the Pinterest Ads UI, append these query parameters to every destination URL:

utm_source=pinterest — identifies Pinterest Ads as the source
utm_medium=cpc — categorizes the channel type
utm_campaign=<your_campaign_name> — for per-campaign breakdown in MER, ROAS, and cohort LTV
utm_content=<creative_or_keyword> — optional, for per-creative reporting

Example tagged URL:

https://yourstore.com/spring-collection?utm_source=pinterest&utm_medium=cpc&utm_campaign=pinterest-spring-2026&utm_content=hero-creative

Step 3 — Revenue auto-attribution kicks in

The first time a visitor lands on your site from a tagged Pinterest Ads URL, the Admaxxer pixel writes the UTM tuple into localStorage for 365 days. Our pixel already captures epik from Pinterest Ads click URLs (per GL#361) — even before native integration ships. When the visitor checks out — even months later, even from a different device that we stitch via email_hash — the order is attributed back to the original Pinterest Ads campaign on the visitor_payments row.

Tag once, our 30-platform classifier (including AI-chat referrers) does the rest.

What's already working today via UTMs

Revenue attribution per campaign — both last-touch and first-touch, on every order row.
Click-ID coverage — epik captured at payment time on visitor_payments rows.
Cohort LTV by acquisition campaign — 7 / 30 / 90-day windows, partial-refund-aware.
MMM contribution analysis — the channel shows up in the geometric-adstock model with full per-campaign granularity.
Cross-session stitch — first-touch UTMs persist 365 days, so a click in March that converts in August still attributes correctly.
One classifier, every channel — tag once and the 30-platform smart-referrer classifier (including AI-chat traffic) handles the rest with no per-source config.

What native integration will add when shipped

UTM tagging gets you accurate revenue-side attribution today. Native API integration adds spend-side reconciliation and platform-side reporting depth:

Spend reconciliation: cost-per-click pulled directly from the Pinterest Ads API alongside revenue.
Promoted-Pin and Idea-Pin and Video-Pin breakdowns in MER/Blended ROAS.
Audience-targeting segment joins onto cohort LTV.
Auto-import of campaign IDs so utm_campaign typos don't fragment your reporting.
Pinterest Conversions API (CAPI) for server-side conversion forwarding from Admaxxer's revenue ledger.

Pinterest Ads specifics

Pinterest appends an epik parameter on every promoted-pin click — Admaxxer's pixel already captures this on the visitor_payments row at payment time (per GL#361). UTM tagging adds campaign-level breakdown on top. Pinterest organic referrers (pinterest.com) are auto-classified by the 30-platform classifier as utm_source=pinterest&utm_medium=social. For Idea Pins and Video Pins where traffic flows differently, the same UTM template applies — the pixel doesn't care which Pinterest ad format generated the click.
