This API is intended to support many cross-site use cases on the web while significantly decreasing cross-site user tracking.
This I2E is for Shared Storage's first output gate, called selectURL. It allows Shared Storage to be used to select from a short list of URLS to be displayed in a Fenced Frame. Gates related to aggregate reporting will follow in future experiments.

Web developers: No signals Other signals: WebView application risksDoes this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No. Goals for experimentationThe intent is for experimenters to try out Shared Storage and see how well it works for them. We expect there to be utility trade-offs and bumps along the road toward optimizing privacy. We also expect it may be necessary to change budgeting parameters and we intend to add new output gate algorithms along the way. So please experiment and provide feedback on the issue tracker to help us improve the API. Experiment ConfigurationThe origin trial for this experiment is shared among various Privacy Sandbox APIs. Our goal is to allow for coordinated experiments to be run by multiple different sites, across multiple APIs in one OT. This shared origin trial, Privacy Sandbox Ads APIs, is a third-party origin trial. To ensure that developers can run coordinated experiments without concern for exceeding page load usage thresholds, this Origin Trial is available for a subset of users by default. Therefore, it will be necessary to feature test to ensure that the API surface you want to use is available after providing your OT token. A second advantage of this configuration is that different experimenters will experiment with the same users, which enables coordination for APIs like FLEDGE across third parties. Ongoing technical constraints As mentioned above, this experiment includes only the selectURL output gate of SharedStorage. We will follow up with aggregate reporting gates in future releases. DebuggabilityThere are no particular debugging APIs made available or Chrome DevTools integrations for this OT. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?All but WebView. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Internal platform tests exist, but they’re internal-only until we’re able to make the fenced frames test infrastructure external. Flag nameOn M104 or greater, the API can be enabled from `chrome://flags/#privacy-sandbox-ads-apis`, or by activating the `SharedStorageAPI`, `FencedFrames`, and `PrivacySandboxAdsAPIsOverride` features. Requires code in //chrome?Only for permission checks.
