How to send Ms Azure push notifications to android device from Postman

Question

I am trying to send Azure push notification to android devices by using Postman. To achieve this i saw post in microsoftDocs but docs saying that This API doesn't support Firebase Cloud Messaging (FCM) yet. Is there any way to send FCM push notification from postman by using MsAzure

Answer 1

Finally i got the solution

URL

https://{namespace}.servicebus.windows.net/{NotificationHub}/messages/?api-version=2015-01

Parameter

• Headers

  Authorization                   {{azure-authorization}}
  Content-Type                    application/json
  ServiceBusNotification-Format   gcm
  

• Body (Body will be according to you. No need to maintain as below)

  {"data":{"gcm.notification.body":"Hi", "gcm.notification.title":"Hi"}}
  

• Pre-request Script

  function getAuthHeader(resourceUri, keyName, key) {
  
      var d = new Date();
      var sinceEpoch = Math.round(d.getTime() / 1000);
      var expiry = (sinceEpoch + 3600);
      var stringToSign = encodeURIComponent(resourceUri) + '\n' + expiry;
      var hash = CryptoJS.HmacSHA256(stringToSign, key);
      var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
      var sasToken = 'SharedAccessSignature sr=' + encodeURIComponent(resourceUri) + '&sig=' + encodeURIComponent(hashInBase64) + '&se=' + expiry + '&skn=' + keyName;
      console.log(sasToken);
      alert(sasToken);
  
      return sasToken;
  }
  postman.setEnvironmentVariable('azure-authorization', getAuthHeader(request.url,"DefaultFullSharedAccessSignature", "xxxxxxxxxxxxxxxxxxxxxx"));
  postman.setEnvironmentVariable('current-date',new Date().toUTCString());
  

In the above code (Pre-request Script) we have to update DefaultFullSharedAccessSignature for that follow the below steps

Go to Azure portal | Access Policies | Copy the DefaultFullSharedAccessSignature and paste some where | from there copy the SharedAccessKey
