 ### Resend Email Verification Link
 
+Use default Laravel email verification notification.

 ```graphql
 mutation {
     resendEmailVerification(input: {
         email: "john.doe@gmail.com",
-        verification_url: {
-            url: "https://my-front-end.com/verify-email?id=__ID__&token=__HASH__"
-# Signed:   url: "https://my-front-end.com/verify-email?id=__ID__&token=__HASH__&expires=__EXPIRES__&signature=__SIGNATURE__"
+    }) {
+        status
+    }
+}
+```
+
+Or use the custom verification flow by uncommenting the `verification_url` argument within the `ResendEmailVerificationInput`:
+
+```graphql
+input ResendEmailVerificationInput {
+    email: String! @rules(apply: ["email"])
+    verification_url: VerificationUrlInput!
+}
+```
