You add a script tag or module, call its methods (show interstitial, show rewarded, load banner) at the right moments, and listen for its callback events. The SDK itself makes the network calls to ad demand; you don&#8217;t run a server to serve ads.<\/p>\n<h2>How does this look by engine?<\/h2>\n<ul>\n<li><b>Unity WebGL:<\/b> your C# code calls a JavaScript function through a <code>.jslib<\/code> plugin, which then calls the ad SDK&#8217;s JS methods (see the <a href=\"https:\/\/docs.unity3d.com\/Manual\/webgl-interactingwithbrowserscripting.html\">Unity manual on browser scripting<\/a>).<\/li>\n<li><b>Godot 4:<\/b> the same round trip goes through the <code>JavaScriptBridge<\/code> singleton.<\/li>\n<li><b>Phaser, Construct, plain JS\/Canvas games:<\/b> call the SDK directly from game code, no bridge layer needed.<\/li>\n<\/ul>\n<p>On error handling: design for an empty result, not a network failure. If no ad is available, the SDK reports an empty\/no-fill outcome &#8211; your game should continue normally rather than block waiting for an &#8220;error&#8221; event that may never fire.<\/p>\n<p>Where you do need a backend: your own save data, leaderboards, or anything server-authoritative. That&#8217;s a separate system from the ad SDK and has nothing to do with how ads are requested or shown.<\/p>\n<p>For monetization, <a href=\"https:\/\/playgama.com\/adv\/\">Playgama Ad<\/a> connects one SDK to 11 demand partners, including Google Ad Manager.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/wiki.playgama.com\/playgama\/bridge-sdk\/getting-started\" rel=\"nofollow noopener\" target=\"_blank\">Playgama Bridge SDK &#8211; getting started<\/a><\/li>\n<li><a href=\"https:\/\/docs.unity3d.com\/Manual\/webgl-interactingwithbrowserscripting.html\" rel=\"nofollow noopener\" target=\"_blank\">Unity manual: interacting with browser scripting<\/a><\/li>\n<li><a href=\"https:\/\/docs.godotengine.org\/en\/stable\/tutorials\/export\/exporting_for_web.html\" rel=\"nofollow noopener\" target=\"_blank\">Godot docs: exporting for the Web<\/a><\/li>\n<li><a href=\"https:\/\/playgama.com\/adv\/\" rel=\"nofollow noopener\" target=\"_blank\">Playgama Ad<\/a><\/li>\n<\/ul>\n<h2>Related questions<\/h2>\n<h3>What happens if no ad is available?<\/h3>\n<p>The SDK reports an empty\/no-fill result.
