+## ServiceExtensionContext.startAbilityByCallWithAccount<sup>10+</sup>
+
+startAbilityByCallWithAccount(want: Want, accountId: number): Promise&lt;Caller&gt;;
+
+Starts an ability with the account ID specified and obtains the caller object for communicating with the ability.
+
+Observe the following when using this API:
+ - If an application needs to call this API to start an ability that belongs to another user, it must have the **ohos.permission.ABILITY_BACKGROUND_COMMUNICATION** and **ohos.permission.INTERACT_ACROSS_LOCAL_ACCOUNTS** permissions.
+ - If an application running in the background needs to call this API to start an ability, it must have the **ohos.permission.START_ABILITIES_FROM_BACKGROUND** permission.
+ - If **exported** of the target ability is **false** in cross-application scenarios, the caller must have the **ohos.permission.START_INVISIBLE_ABILITY** permission.
+ - The rules for using this API in the same-device and cross-device scenarios are different. For details, see [Component Startup Rules (Stage Model)](../../application-models/component-startup-rules.md).
+
+**System capability**: SystemCapability.Ability.AbilityRuntime.Core
+
+**System API**: This is a system API and cannot be called by third-party applications.
