{% hint style="info" %}
Customizing is possible only in the initial step of the configuration of SensePass's SDK client.\
If unfimiliar with the configuration step, refer to the [Config](https://docs.sensepass.com/sensepay/transaction-api/sdk-and-iframes/javascript-ui-sdk#step-1-configuration) step.
{% endhint %}

### Customizable themes

#### When configuring the SDK, you may set the following code as the configuration object:

<pre class="language-javascript" data-line-numbers><code class="lang-javascript">const spClient = SensePassFrontEndSDK.config({
   mode: "sandbox", // "sandbox" | "production"
   debug: true, // optional for logs
   visualizer: true, // optional visual logs, requires HTML with id="sensepass-front-end-visualizer"
<strong>   clientId: 'aee8d2cdc1cb...', // a SensePass's "clientId"
</strong>   methodType: "manual_capture", // type for the transaction, defaults to "manual_capture", enum: "manual_capture" | "tokenize"
   theme: { // optional theme for various packages
	/** angular material provides extensive documentation on customizing their theme
	* you can find it at: https://material.angular.io/guide/theming */
	material: "https://pay.sandbox.sensepass.com/publicAssets/themes/custom-sample-material.theme.css", // sample for a customized material theme
	sensepassEcommerce: "https://pay.sandbox.sensepass.com/publicAssets/themes/custom-sample-ecommerce.theme.css", // sample for a customized sensepass theme
	paymentMethodGrid: "horizontal", // horizontal | vertical style of the payment options
	config: {} // a configuration object for specific payment methods text/animations
   }
})
</code></pre>

3. Save your themes in a hosting site of your choosing and set their URL in the config JSON.
