Pinterest Ads integration — coming soon

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 — 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.
• Server-side forwarding to Pinterest is not available yet.

Pinterest Ads specifics

Pinterest appends an epik parameter on every promoted-pin click — Admaxxer's pixel already captures this on the payment record at payment time. 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.

Frequently asked

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

The Admaxxer pixel captures 13 click-IDs on every payment record 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?

Not available yet. Server-side forwarding today is Meta, TikTok, and Klaviyo. Pinterest is not one of them.

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.
