    WHAT THIS ENABLES

    Datahash API to LinkedIn Leads CAPI

    Datahash API to LinkedIn Leads CAPI: post your qualified-lead and pipeline signals to one REST endpoint and Signals reports deal-stage progress so LinkedIn favors opportunities that advance, hashed and consent-checked server-side before LinkedIn sees it.

    • Signals reports deal-stage progress so LinkedIn favors opportunities that advance, from events your backend posts server-side.
    • LinkedIn focus on the deals that actually advance, without a pixel, a connector, or a nightly export.

    WHAT FLOWS WHERE

    Datahash API to Leads CAPI, mapped.

    Your backend posts each event to the Datahash API, which hashes and consent-screens it server-side, then LinkedIn's Leads Conversions API records the lead conversions for opportunity-stage weighting.

    WHO THIS IS FOR

    Built for the teams that own the number.

    B2B advertisers whose LinkedIn forms fill faster than they qualify, whose engineers would rather POST an event than maintain a connector.

    Backend and platform teams driving LinkedIn lead-stage optimization by sending qualified-lead and pipeline signals straight from their own stack.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Create an API key in the Signals console and point your backend at the endpoint that feeds LinkedIn's Leads Conversions API.

    2. Map

      Map your event payload to LinkedIn's Leads Conversions API fields once; per-request validation flags bad events instead of dropping the batch.

    3. Deliver

      Post events as they happen and Signals reports deal-stage progress so LinkedIn favors opportunities that advance, hashing server-side, with opportunity-stage weighting shown in the debugger.

    WHAT YOU GET

    What ships with this use case.

    LinkedIn focus on the deals that actually advance from a single server-side call.

    Campaign focus on the deals that advance, with identifiers hashed at ingestion or sent pre-hashed.

    Per-event status and match feedback on opportunity-stage weighting from LinkedIn's Leads Conversions API, returned inline in the live debugger.

    FAQ

    Asked on almost every call.

    Which backends can send to LinkedIn Leads CAPI through the Datahash API?

    Any backend that can make an HTTPS request. You POST qualified-lead and pipeline signals as JSON to one documented endpoint and Signals forwards the lead conversions to LinkedIn's Leads Conversions API; identifiers are hashed at ingestion or sent pre-hashed, and B2B advertisers whose LinkedIn forms fill faster than they qualify track opportunity-stage weighting in the debugger.

    How fresh are LinkedIn Leads CAPI events sent over the API?

    As fresh as you post them. The API accepts events in near real time, so LinkedIn focus on the deals that actually advance reaches LinkedIn moments after your backend fires the call, with per-event status returned inline. There is no batch window and no scheduled read, which keeps opportunity-stage weighting current for the teams driving LinkedIn lead-stage optimization.
