How does Visprisca connect to an exchange (OpenRTB basics)?

Reviewed by Visprisca Ad Tech Engineering Team•Last updated: October 2026
Direct Answer

Visprisca connects to ad exchanges and SSPs using the OpenRTB 2.5 protocol over high-throughput HTTPS JSON endpoints. The exchange sends an HTTP POST bid request; Visprisca parses targeting and floor parameters, executes rule validation and algorithmic valuation, and returns an OpenRTB bid response within milliseconds.

Detailed Explanation

OpenRTB (Real-Time Bidding) is the open technical communication standard governed by the IAB Tech Lab that allows ad exchanges and DSPs to communicate programmatically.

When a supply partner sends an ad opportunity to Visprisca, it delivers a JSON document containing device information, publisher ID, geo coordinates, IP, and ad placement specifications (e.g. 300x250 banner or 1920x1080 interstitial).

Visprisca's gateway infrastructure receives this stream, performs pre-bid fraud checks, evaluates campaign targeting rules, executes bid shading, and returns a JSON response containing the bid price, creative markup, and win notification tracking pixels.

Technical Definition: OpenRTB BidRequest / BidResponse

The standardized JSON object schema defining auction context, user signals, ad unit specifications, and pricing exchanged between SSPs and DSPs.

Core JSON Bid Exchange Flow

An exchange sends an auction opportunity for an in-app banner ad.

›1. Bid Request Received: { id: 'auc_1029', imp: [{ id: '1', banner: { w: 320, h: 50 }, bidfloor: 1.20 }], app: { bundle: 'com.news.daily', id: 'app_55' } }
›2. DSP Processing: Targeting match found (US, iOS, News category). Max valuation: $2.10. Floor: $1.20. Shaded bid calculated: $1.45.
›3. Bid Response Sent (<100ms): { id: 'auc_1029', seatbid: [{ bid: [{ id: 'bid_99', impid: '1', price: 1.45, adm: '<creative_tag>' }] }] }

Strict compliance with OpenRTB 2.5 ensures seamless interoperability across any global exchange.
