Azure Notification Hubs: FCM legacy API support deprecation

The Azure updates record lists Mar 2027 as the retirement date for Firebase Cloud Messaging (FCM) legacy API support in Azure Notification Hubs. The announcement text states that Google stops supporting FCM legacy HTTP on June 20, 2024.

Retires approx., Mar 2027

· The vendor gives a month, not a day.

What breaks

FCM is used to send push notifications to Google Play supported Android devices, and Azure Notification Hubs previously communicated with FCM using the Legacy HTTP protocol. The announcement states that Google stops supporting FCM legacy HTTP on June 20, 2024, and that the FCM legacy API is deprecated by July 2024. It states that all customers must migrate applications and notification payloads to the new format (FCM v1) before June 20, 2024, and asks them to follow the migration steps before 1 June 2024. The announcement text does not mention Mar 2027; that date comes from the Azure updates record.

What to do

Migrate your applications and notification payloads to the new format (FCM v1). The announcement asks customers to follow the FCM v1 migration steps before 1 June 2024. Questions can be posted at Microsoft Q&A: https://aka.ms/anhfcmv1.

Replacement
