Define platform and locale-specific promo banners

Imagine you have an ecommerce sale coming up and you want to enable a promotional splash page in your app. Further, imagine you want to customize this splash page to the same locale that your user has set on their device. You can define a parameter promo_splash_graphic and set its value to static URLs (hosted on Firebase Storage or elsewhere) and then reference them dynamically in your app.

You could then assign different values to Android and Apple for locales that are most important to your promotional marketing campaign. If you need to trigger promotions at a specific time, you can use Remote Config time conditions, and you can also use real-time Remote Config to ensure that the changes are pulled soon after the template is published, and then you can activate them as-needed within your app.

You can also use the Remote Config backend APIs to update the parameter values programmatically and then trigger the functionality from a cron job.
