PebblePost

PebblePost is a New York-based commerce marketing platform that pioneered Programmatic Direct Mail (PDM) and now also operates a Performance CTV product. Its Performance Marketing Engine turns first-party website intent signals, household identity and transaction data — surfaced through the PebblePost Graph — into targeted physical mail and connected-TV campaigns for retail and direct-to-consumer brands, with conversion measurement reported through a Performance Dashboard. Brands integrate by installing the PebblePost JavaScript tag (a window._pp client-side collector served from cdn.pbbl.co) and by syncing commerce data through connectors such as Shopify. Live API hosts run at api.pebblepost.com and api.pbbl.co, but PebblePost publishes no public developer portal, API reference, OpenAPI definition or self-serve API keys — API access is arranged through a PebblePost account team.

PebblePost publishes 2 APIs on the APIs.io network. Tagged areas include Company, Marketing, Advertising, Direct Mail, and Connected TV.

PebblePost’s developer surface includes documentation, getting-started guide, support, engineering blog, authentication, and 19 more developer resources.

  description: The PebblePost JavaScript tag is the provider's public client-side integration surface. Brands drop a script
    on their site that populates a window._pp array with a Brand ID (brid) and Brand Customer ID (brcid), plus optional conversion
    fields (orderId, orderValue), email and sessionId, then asynchronously loads a per-brand collector script from cdn.pbbl.co.
    It is the mechanism PebblePost uses to capture website intent and conversion events that drive Programmatic Direct Mail
    and Performance CTV targeting and attribution.

  detail: PebblePost runs live API hosts but publishes no developer program at all — api.pbbl.co is an AWS API Gateway that
    answers every path, including /openapi.json, with HTTP 403 "Missing Authentication Token", and the only public docs site
    (docs.pebblepost.com, a Help Scout help center) covers dashboard reporting and creative specs, still telling integrators
    in 2026 to email a Shopify API key and password to "your PebblePost Account Manager" — three years after PebblePost announced
    a Shopify public app that was supposed to end exactly that practice.
