+### Send Authentication Template message
+For static links, you don't need to include `MessageTemplateQuickAction` model because the WhatsApp template has a static `CallToAction` link with no input required from the user.
+
+#### Example
+
+`auth_sample_template` template:
+
+This sample template sends authentication template message with one-time password buttons. More details can be find [here](https://developers.facebook.com/docs/whatsapp/cloud-api/guides/send-message-templates/auth-otp-template-messages)

+
+The template json looks like this:
+
+```json
+[
+  {
+    "type": "BODY",
+    "text": "*{{1}}* is your verification code.",
+    "add_security_recommendation": false,
+    "example": {
+      "body_text": [
+        [
+          "123456"
+        ]
+      ]
+    }
+  },
+  {
+    "type": "BUTTONS",
+    "buttons": [
+      {
+        "type": "URL",
+        "text": "Copy code",
+        "url": "https://www.whatsapp.com/otp/code/?otp_type=COPY_CODE&code=otp{{1}}",
+        "example": [
+          "https://www.whatsapp.com/otp/code/?otp_type=COPY_CODE&code=otp123456"
+        ]
+      }
+    ]
+  }
+]
+```
+
+Create one `MessageTemplateText`, one `MessageTemplateQuickAction` params. Then assemble your list of params values and your `WhatsAppMessageTemplateBindingsButton` by providing the parameters in the order that the parameters appear in the template content. The order also matters when defining your bindings' buttons.
+
+```csharp
+  // Send auth sample template message
+  string templateNameWithauth = "auth_sample_template";
+  string oneTimePassword = "3516517";
+  var messageTemplateWithAuth = new MessageTemplate(templateNameWithauth, templateLanguage);
+  WhatsAppMessageTemplateBindings auth_bindings = new();
+  var bodyParam2 = new MessageTemplateText(name: "code", text: oneTimePassword);
+  var uri_to_copy = new MessageTemplateQuickAction("url") { Text = oneTimePassword };
+
+  auth_bindings.Body.Add(new(bodyParam2.Name));
+  auth_bindings.Buttons.Add(new WhatsAppMessageTemplateBindingsButton(WhatsAppMessageButtonSubType.Url.ToString(), uri_to_copy.Name));
+  messageTemplateWithAuth.Values.Add(bodyParam2);
+  messageTemplateWithAuth.Values.Add(uri_to_copy);
+  messageTemplateWithAuth.Bindings = auth_bindings;
+
+  TemplateNotificationContent templateContent5 =
+      new TemplateNotificationContent(channelRegistrationId, recipientList, messageTemplateWithAuth);
+  Response<SendMessageResult> sendTemplateMessageResult5 =
+      notificationMessagesClient.Send(templateContent5);
+```
