NextRoll Server-to-Server (S2S) Event API is one of 4 APIs that [AdRoll](https://apis.io/providers/adroll/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Event, Conversions, Attribution, Server-to-Server, and Advertising. The published artifact set on APIs.io includes API documentation and an API reference.

Server-side event ingestion API for sending user events and conversions to AdRoll directly from your own servers, complementing the AdRoll pixel and mobile measurement partner integrations. Accepts batched JSON events keyed by an AdRoll click ID or first-party cookie, with hashed email, device and user identifiers, covering both B2C events (page view, product search, add to cart, purchase) and B2B/ABM events (high-value page, gated content, demo request, form fill). Supports a dry_run validation mode and gzip compression.
