Bid expiration required for integrations

Demand partner integrations must set exp (bid expiration, in seconds) on every bid.

Set it to how long your bid and creative actually remain valid after your response.
CloudX SDKs use it to decide how long a loaded ad can wait before it is shown.

CloudX Exchange on by default

CloudX Exchange is now available to publishers as one additional bidder that routes bids from participating third-party demand partners.

An admin accepts the CloudX Exchange addendum in the dashboard. If the account manager hasn’t turned CloudX Exchange on or off for the account before, accepting turns it on and selects it on the line items in the live configuration, and new line items start with it selected.
Publishers manage it per line item under Bidders. It isn’t selected on line items whose only bidders are CloudX Direct or AppLovin waterfall, or on native reel line items.
Demand fills only on apps whose app-ads.txt file includes the CloudX lines, and only for ad formats the exchange partners support.

CloudX-rendered iOS interstitial and rewarded VAST ads can now open the App Store sheet before the first end card, keep an SKOverlay on screen for the rest of the ad, and show a sequence of end cards.

Eligible bids get AutoStore and the SKOverlay by default. Set ext.cloudx.render.auto_store or ext.skadn.skoverlay to customize or opt out, and ext.cloudx.render.player_config.cards to send your own end cards.
Requires CloudX iOS SDK 3.10 or later and bid.ext.skadn.itunesitem.

Intent IQ passthrough

CloudX now forwards publisher-provided Intent IQ IDs under intentiq.com with atype: 1.

Publishers pass the ID with setUserKeyValue("intentiq.com", id); no SDK update is required.
CloudX passes the ID unchanged and does not run Intent IQ server-side resolution. Demand partners activate intentiq.com IDs through an Intent IQ partnership.

EUID passthrough

CloudX now forwards publisher-provided EUID advertising tokens under euid.eu. EUID is the European counterpart to UID2 and uses atype: 3.

Publishers pass the advertising token with setUserKeyValue("euid.eu", token); no SDK update is required.
CloudX passes the token unchanged. Authorized demand partners decrypt it through their EUID bidstream integration.

Extended identifiers

CloudX now forwards publisher-provided UID 2.0, LiveRamp, and ID5 values on bid requests. Publishers pass them with the existing setUserKeyValue API; no SDK update is required.

Publisher keys are uidapi.com (UID2 advertising token), liveramp.com (LiveRamp ATS envelope, not a RampID), and id5-sync.com (ID5 universal UID).
OpenRTB 2.6 bidders read user.eids. OpenRTB 2.5 bidders read user.ext.eids.
CloudX does not generate, decrypt, or replace these values and does not run LiveRamp Sidecar.

Publisher setup: Android, iOS, Unity, React Native, and Flutter

zstd bid compression

CloudX now supports zstd compression for OpenRTB traffic with demand partners, on both bid requests and bid responses.

Bid requests can be sent with Content-Encoding: zstd; gzip remains supported.
When CloudX advertises Accept-Encoding: gzip, zstd, partners may respond with gzip or zstd.
Contact CloudX to enable zstd for your bidder endpoint.
