How to get customer data from email URL hit by customer

[Former Member]

Hi experts,

I am sending registration successful email. There I have to implement newsletter unsubscribe functionality just by clicking one URL from mail. So when the customer clicks on the unsubscribe hyperlink/URL in the email, then I need to get the customer data or customer email in hybris back-end so that I can check its availability in hybris DB an remove it from newsletter table. Can you please guide me how to get the customer data from emails URL hits?

Hi Abhinandan

I think a better way is to generate a uuid using UUID class in java.util package. Save the UUID in your DB and send an email to customer with an unsubscribe link as
www.xyz.com/email/unsubscribe/<your unique UUID>

then create a controller class with

 @Controller
 @RequestMapping("/email/unsubscribe") 
 public class EmailUnsubscribeController
 {
   @RequestMapping("/{uuid}")
   public void unsubscribe(@PathVariable String uuid) 
   { 
      CustomerModel customer = (CustomerModel)userService.getUserForUUID(uuid);
       customer.setSubscription(false);
       modelService.save(customer);
   }
 }

It is not a good idea to access service layer in controller, so use the facade-service pattern that hybris uses out of the box. This code snippet was just for the illustration purposes.

the idea is to use a random UUID in emails for these kind of task me know how you go.

Thanks a lot for your reply. That's a good approach. I will pass the UUID of the customer from email context in the email. Then I will follow your steps. Thanks a lot.
