To send web push notifications, the client website must be configured to show the popup. The pop-up appears when the customers navigate to the website. When the customers accept to receive web push notifications, a service worker is created in the browser's background. The service worker constantly listens to the push messaging server and shows the notification even when the website is closed.

             userId will be generated by IMIConnect and passed to callback function)//
          //var  deviceProfile = new IMI.ICDeviceProfile(deviceId);//
          IMI.IMIconnect.register(deviceProfile, callback);
        }
    } catch (err) {
        console.log(err);
    }
</script>

                }

            };
            var deviceProfile=new IMI.ICDeviceProfile(deviceId, userId);  
           //here user id is  optional (If user id not there user can call deviceID,  
             userId will be generated by IMIConnect and passed to callback function)//
          //var  deviceProfile = new IMI.ICDeviceProfile(deviceId);//

Now the web push configuration is complete to display a popup when the default web page is loaded.

  1. When the web page is loaded a popup appears. When a user clicks on Allow, unique ids are generated and stored in the profile manager. The ids generated are:
Browser
IDs

Chrome

chrome_pushid

Firefox

firefox_pushid and key

Sending Push Messages to Customers

You can send push messages to customers in many methods. Below is one of them:

  1. When the customers click Allow button, the push details are stored in the profile manager.
  2. Get the profiles based on appid using getAppProfile API. You will get all the browser-specific push ids.
  3. Use Messaging API, to send push messages to the push ids.
