# Adds Account Signals, Account Evaluations, and Account Activity APIs in public preview ## What’s new Introduces the following v2 APIs in public preview: - [Account Evaluation](https://docs.stripe.com/api/v2/signals/account-evaluations.md?api-version=2026-08-26.preview): Request evaluations for the `user_account_sharing` and `user_multi_accounting` [requested_signals](https://docs.stripe.com/api/v2/signals/account-evaluations/object.md?api-version=2026-08-26.preview#v2_signals_account_evaluation_object-requested_signals) types. This API sends the `v2.signals.account_evaluation.complete` event when all pending evaluation signals finish processing so you can use the risk signal result to direct your decision. - [Account Activity](https://docs.stripe.com/api/v2/signals/account-activities.md?api-version=2026-08-26.preview): Create account activity events, such as login and registration attempts, to use in requesting evaluations, then report the outcome to Stripe to reconcile your risk-signal based decisions and improve future evaluations. You can create retrieve, and delete recorded activities. - [Account Signal](https://docs.stripe.com/api/v2/signals/account-signals.md?api-version=2026-08-26.preview): List and retrieve individual risk signals generated for accounts. ## Impact You can now send account activity data, such as login and registration attempts, to Stripe’s Signals APIs and request on-demand evaluations about whether your accounts might be engaged in account sharing or multi-accounting. Stripe returns a risk score to help you manage your abuse prevention strategy. You can also report the action you take based on the risk evaluation results and look up individual past signals. ## Changes #### REST API | | Change | Resources | | --- | --- | --- | | | Added |
