When do clients pick up config changes?

Clients fetch the latest config on each call to the Remote Config API. Most games fetch once at startup and cache locally for the session.

Can I use Remote Config for A/B testing?

Yes. You can create separate config keys for each variant and assign them in your client logic. horizOn does not split traffic automatically, but it provides the data layer you need.

Is there a limit on the number of config keys?

The number of remote config entries is generous on all tiers. Check your plan details in the horizOn dashboard for exact limits.

Remote Config & Feature Flags for Games

Instant Value Updates

Change any string, number, or boolean config value from the dashboard and clients receive it on their next fetch.

No App Store Delays

Avoid review cycles for balance changes, event toggles, or A/B test parameters by controlling them remotely.

Typed Key-Value Store

Store any configuration as a named key-value pair that your SDK reads at runtime with a strongly typed getter.

Quick Integration

Remote Configuration

Unity (C#)

// Unity C#: Remote Config
using PM.horizOn.Cloud.Manager;
using UnityEngine;

// Every value in one request at startup (cached afterwards)
var configs = await RemoteConfigManager.Instance.GetAllConfigs();

// Typed getters with a default for a missing key
int maxPlayers = await RemoteConfigManager.Instance.GetInt("max_players", 4);
bool eventActive = await RemoteConfigManager.Instance.GetBool("holiday_event", false);
Debug.Log($"Max players: {maxPlayers}, event active: {eventActive}");

REST

# REST API: Remote Config

# Fetch all remote configs
curl -X GET https://horizon.pm/api/v1/app/remote-config/all \
  -H "X-API-Key: YOUR_API_KEY"

# Fetch a single config value by key
curl -X GET https://horizon.pm/api/v1/app/remote-config/max_players \
  -H "X-API-Key: YOUR_API_KEY"

These examples use the Unity SDK (C#) and the REST API. Godot and Unreal have the same calls in their own SDKs: see the quickstart
