Quick question about configuring the Web Messaging deployment to customize colors and launcher position. I am injecting the configuration object directly into the global genesiWebMessaging namespace before the SDK loads, but the UI renders with default values. I have verified the JSON is valid and the keys match the documentation for launcher.position and theme.colors. The script runs without errors, yet the widget remains top-right with the default blue accent. I am using the latest SDK version (3.2.1) and testing on Chrome 118. Here is the config block I am pushing to the window object:
window.genesiWebMessaging = {
config: {
launcher: {
position: 'bottom-left',
enabled: true
},
theme: {
colors: {
primary: '#FF5733',
background: '#FFFFFF'
}
}
}
};
400 Bad Request: Invalid configuration schema
I see this error in the console if I try to pass the config via the initialization API call instead of the global object, but the global object approach silently ignores the settings. Is there a specific timing issue with when the SDK reads this object? I need this fixed before the Lagos morning rush.
If I remember right, the issue often stems from the timing of the configuration injection relative to the SDK’s initialization sequence. The genesiWebMessaging object must be fully populated before the script tag fetches the core library, otherwise the SDK defaults to its internal constants.
window.genesiWebMessaging = window.genesiWebMessaging || {};
window.genesiWebMessaging.config = {
launcher: {
position: 'bottom-right', // Ensure exact string match
offset: { x: 20, y: 20 }
},
theme: {
colors: {
primary: '#FF5733'
}
}
};
Error: Configuration not applied. Default theme loaded.
Verify that your script tag for the SDK is placed after this configuration block in the HTML head or body. If you are using a framework like React or Next.js, ensure the global variable is set in a useEffect hook that runs before the SDK component mounts, or use a dynamic import strategy to guarantee execution order. The browser cache might also be serving an older version of the widget script; try a hard refresh or append a version query parameter to the SDK URL.
My usual workaround is to bypassing the global configuration object entirely and using the Programmatic API provided by the SDK instance. The global genesiWebMessaging config is parsed during the initial load phase, and if your Laravel Blade template renders the script tag before the configuration script executes-even by a few milliseconds-the SDK locks in the defaults. Since I handle this in PHP, I ensure the config is inline before the script, but a more robust approach is to wait for the genesys.ready event. This guarantees the SDK is fully loaded before we attempt to override the theme.
Here is how I structure the override in my Laravel views. Instead of relying on the pre-load config, I attach a listener that fires once the widget is ready. This method is significantly more reliable for production environments where asset loading order can vary due to caching or CDNs.
window.addEventListener('genesys.ready', () => {
const widget = window.genesiWebMessaging;
if (widget && widget.setConfig) {
widget.setConfig({
launcher: {
position: 'bottom-right',
xOffset: 20,
yOffset: 20
},
theme: {
colors: {
primary: '#FF5733',
secondary: '#33FF57'
}
}
});
}
});
The setConfig method allows you to push updates after initialization. I also recommend checking the browser console for any CSP (Content Security Policy) violations that might block the inline script execution. In my Laravel setup, I had to explicitly whitelist the nonce for the script tag containing this listener. If you are using a CDN, ensure the script tag has defer or is placed at the end of the body to minimize race conditions. This approach has eliminated the random default rendering issues I faced during peak traffic hours.
Have you tried verifying the exact property structure within the configuration object against the latest SDK documentation? The suggestion above correctly identifies the timing issue, but the structure of the configuration object is equally critical. The documentation states, “The configuration object must be attached to the window.genesiWebMessaging namespace before the SDK script is loaded. Any properties defined after the SDK initialization will be ignored.”
In my experience with OAuth token services, timing is often the culprit, but incorrect nesting of properties is just as common. You are likely defining theme and launcher at the root level, but the SDK expects them within a specific config object.
Here is the correct structure:
window.genesiWebMessaging = window.genesiWebMessaging || {};
window.genesiWebMessaging.config = {
organizationId: 'your-organization-id',
launcher: {
position: 'bottom-right',
enabled: true
},
theme: {
colors: {
primary: '#FF5733',
secondary: '#33FF57'
}
}
};
Ensure this script runs before the following tag:
<script src="https://files.genesiswebmessaging.com/sdk/latest/gwmsdk.js"></script>
If you are using a server-side framework like Next.js or Laravel, ensure the configuration script is rendered in the <head> or immediately before the SDK script in the <body>. The SDK does not support dynamic configuration updates after initialization. If the widget still appears with default values, check the browser console for any warnings related to “configuration not found” or “invalid property”. The documentation explicitly warns, “Invalid configuration properties are silently ignored to prevent runtime errors.”
