how to spoecific platform type registrations from Azure Notification Hub?

Mahalakshmi 0

Hi,

I am using Azure Notification Hub to send push notifications. My application is developed in the .NET framework. Currently, I am using GetAllRegistrationsAsync to retrieve all the registrations. However, this method does not provide access to the platform type of each registration. I need to get only FCM/GCM registrations and Apple registrations from the Notification Hub.

@Mahalakshmi Have you gone through these method GetRegistrationsByChannelAsync() to pull the registration of a specific channel, or you can look at this method GetRegistrationsByTagAsync() pull the registration by tags as well.

Alternatively, you can use find the relevant REST API for the above methods in this documentation here.

Read Registration by channel.

Read Registration by Tags.

Hope this helps, let me know if you have any further questions on this.

Hi @VenkateshDodda-MSFT I too am interested in this solution.

I can successfully use the "GetAllRegistrationsAsync" method to return my registrations but I am struggling to filter these registrations where the platform is "FCM".

I want to re-register all FCM instillations as FCM v1 so that when our back end changes are deployed to deliver notifications via FCM v1 that all Users still receive them.

After some further research I think I have a solution now, broken down into a few steps, although I'm not sure how performant this will be:

Use "GetAllRegistrations" to retrieve all registrations

Filter out those registrations that have an Installation ID as a tag (created on initial registration)

Loop around the registrations which do have an InstallationID tag and use that to call the "GetInstallationAsync" method. Foreach installation, if the "installation.Platform == NotificationPlatform.Fcm" then add to a List object

Loop around the list of "fcmInstallations" and update the Platform to be "NotificationPlatform.FcmV1" and call "CreateOrUpdateInstallationAsync" which is an idempotent method so can be called to update any existing installations.

Hey @Reece Kindon , I have the same problem as yours to migrate to FCM V1 now.
However, in the response of "GetAllRegistrations", None of the registrations have the installation_id as a tag.
Do you know of any other ways we could filter out the FCM registrations?

You can get the type of the RegistrationDescription and filter through that.
To following example should give you an idea on how to do it.

var response = await hub.GetAllRegistrationsAsync(0); response.ToList().ForEach(regDesc => { if(regDesc.GetType() == typeof(FcmRegistrationDescription)) { //do transform stuff for change to FcmV1RegistrationDescription and reregister } });
