WordPress Fire Push DocumentationWordPress Fire Push Getting StartedViewed 905 times

Google has shut down the legacy Firebase FCM API and replaced it with the new, more secure HTTP v1 method. You can find an official Firebase cloud messaging HTTP1 upgrade guide here. The old method was switched off in 2024.

However in order to keep our web push messaging plugin for WordPress up and running you need to change the configuration. Please follow these simple steps:

  1. Download & Install latest version 1.4.0
  2. Go to: https://console.firebase.google.com/
  3. Open your project
  4. Click on the gear icon on top left to open project settings
  5. Go to service accounts
  6. Click on generate new private key, confirm and download the JSON file

  1. Go to our plugin settings
  2. Open firebase credentials section
  3. Now upload the JSON file into the first setting option
    You may need to allow json files to be uploaded.
  4. Done. That is it. The new method is also capable of sending more messages than before.
