+Check the authorization status for sharing (writing) the specified data type.
+
+Status will be one of `"NotDetermined"`, `"SharingDenied"`, `"SharingAuthorized"`.
+
+```javascript
+AppleHealthKit.authorizationStatusForType(
+  "initHealthKit", (error, status) => {
+    if (status) {
+      console.log("status is", status)
+    }
+  }
+)
+```
+
+There is no way to check authorization status for read permission, [see this](https://developer.apple.com/documentation/healthkit/hkhealthstore/1614154-authorizationstatusfortype?language=objc).
