LinkedIn Conversions API,
delivered server-side.

LinkedIn is the B2B advertising platform — Sponsored Content, InMail, lead gen forms, and the most precise professional targeting in digital. But B2B CPMs are premium, sales cycles stretch across months, and the browser-side Insight Tag was never built for this kind of attribution. Ad blockers strip it, cookies expire before deals close, and the identifiers it captures are too thin to match reliably.

Ingest Labs sends your events to the LinkedIn Conversions API server-side — enriched with first-party email for high-confidence matching, deduplicated against the Insight Tag, and gated by user consent. B2B match rates climb, long-cycle attribution works, and every dollar of LinkedIn spend maps to real pipeline.

Why LinkedIn + Ingest Labs

LinkedIn advertising is expensive by design — you're reaching decision-makers with verified professional profiles. That premium makes attribution accuracy existential. If you can't prove that a $50 CPC Sponsored Content click led to a $200K deal six weeks later, you can't justify the spend. The Insight Tag, running in the browser, was never built for this job. It depends on cookies that Safari kills in 7 days, and it's the first script ad blockers remove.

LinkedIn's Conversions API accepts server-side events matched primarily on hashed email — the one identifier that B2B marketers reliably collect through forms, gated content, and CRM records. When you send a conversion with the prospect's business email attached, LinkedIn matches it to a member profile with far higher confidence than the Insight Tag's cookie-based approach. This is what makes long-cycle B2B attribution possible.

Ingest Labs handles the pipeline end to end. One install captures events from your site and CRM, enriches them with first-party identity from our ID graph, hashes PII to LinkedIn's spec, deduplicates against the Insight Tag — and delivers it all to LinkedIn's CAPI in real time. Your Campaign Manager finally shows the full picture: from ad impression to closed deal.

Key benefits

Every signal LinkedIn needs to attribute your B2B campaigns — captured server-side, matched on email, and compliant.

  • Capture B2B conversions the Insight Tag misses due to ad blockers and cookie expiry
  • Lift LinkedIn match rates with first-party email — the strongest B2B identifier
  • Close the loop on long-cycle attribution from ad click to closed deal
  • Deduplicate Insight Tag + CAPI events automatically to prevent double-counting
  • Enforce GDPR, CCPA, and ePrivacy compliance — events only fire with user consent
  • No browser performance penalty — conversion events fire from your server, not the user's device

Frequently Asked Questions

What is LinkedIn Conversions API (CAPI)?

LinkedIn Conversions API is a server-to-server integration that sends conversion events directly from your server to LinkedIn — bypassing ad blockers, browser restrictions, and cookie limitations that affect the Insight Tag. Ingest Labs handles the full CAPI pipeline, including first-party email matching and event deduplication.

How does this help with B2B attribution?

B2B sales cycles are long — weeks to months between a LinkedIn ad click and a closed deal. Browser cookies expire, users switch devices, and the Insight Tag loses the thread. Server-side CAPI with first-party email matching lets you attribute conversions back to the original LinkedIn campaign regardless of when or where the conversion happens.

Will running CAPI double-count my conversions?

No. Ingest Labs attaches a unique conversion event identifier to every browser and server event. LinkedIn deduplicates them on ingestion, so you see one conversion per action in Campaign Manager — never two.

What data does LinkedIn CAPI accept for matching?

LinkedIn matches events to members using hashed email (the primary identifier), plus first name, last name, company name, and job title. Server-side delivery lets you pass the full set — especially email — which is often unavailable to the browser-side Insight Tag. This is what lifts B2B match rates significantly.

Is this GDPR and CCPA compliant?

Yes. Ingest Labs integrates with your consent management platform (OneTrust, Cookiebot, or custom) and only forwards events to LinkedIn when the user has granted marketing consent. Every consent decision is logged for audit, and PII is hashed before transmission.

How long does setup take?

Most customers are live on LinkedIn CAPI in under 24 hours. The setup involves connecting your LinkedIn ad account, mapping conversion events, and configuring first-party identity enrichment — all handled by Ingest Labs with minimal developer involvement.
