If you're feeding Firebase analytics data into your Google Analytics 4 properties you can use our Google Analytics 4 data source.
If you're not using GA4 there are a few other methods you could use to display this data in Geckoboard:
Spreadsheets
If you can export the data from Firebase as a spreadsheet, you can use our Spreadsheets integration to build widgets from it. This is the simplest solution, but it has the drawback of not being automated.
One way to automate this process is to use a tool such as Zapier, Make or Parabola.io to export data from a product, and automatically transfer this data to a Google Sheet. Then display this data in Geckoboard using our Spreadsheets integration.
Datasets API
If you have programming experience or a developer available on your team, you can use our Datasets API to display data on your dashboard from a custom data source.
You would need to write a script/application that authenticates and connects to the Firebase API and requests the data. Then you can format the data as required and 'push' a dataset to Geckoboard for display.
