+## APIs
+
+FormLink(value: {
+  action: string;
+  moduleName?: string;
+  bundleName?: string;
+  abilityName: string;
+  params: Object;
+})
+
+**Parameters**
+
+| Name     | Type| Mandatory| Description                                                    |
+| ----------- | -------- | ---- | ------------------------------------------------------------ |
+| action      | string   | Yes  | Action type.<br>- **"router"**: redirection to the specified UIAbility of the widget provider.<br>- **"message"**: custom message. If this type of action is triggered, the [onFormEvent()](../apis/js-apis-app-form-formExtensionAbility.md#onformevent) lifecycle callback of the provider FormExtensionAbility is called.<br>- **"call"**: launch of the widget provider in the background. If this type of action is triggered, the specified UIAbility (whose [launch type](../../application-models/uiability-launch-type.md) must be singleton) of the widget provider is started in the background, but not displayed in the foreground. This action type requires that the widget provider should have the [ohos.permission.KEEP_BACKGROUND_RUNNING](../../security/permission-list.md#ohospermissionkeep_background_running) permission.|
+| moduleName  | string   | No  | Name of the target module when **action** is **"router"** or **"call"**. This parameter is optional. |
+| bundleName  | string   | No  | Name of the target bundle when **action** is **"router"** or **"call"**. This parameter is optional.   |
+| abilityName | string   | Yes  | Name of the target UIAbility when **action** is **"router"** or **"call"**. This parameter is mandatory.|
+| params      | Object   | Yes  | Additional parameters carried in the current action. The value is a key-value pair in JSON format. For the **"call"** action type, the **method** parameter (mandatory) must be set and its value type must be string.|
+
+## Attributes
+
+The [universal attributes](ts-universal-attributes-size.md) are supported.
+
+## Events
