# Example
Below you will find code samples for setting up the Yandex Games SDK synchronously and asynchronously.
{% list tabs %}
* Synchronous connection
Example specifics:
- [Callback functions](*key_callback) are not set for the first ad call.
- Every callback function possible is specified for the second call and each subsequent call.
- A `'click'` event handler is assigned to the **Show ads** button (an ad is called on each button click).
```html showLineNumbers
Page example with SDK configured synchronously
```
* Asynchronous connection
Example specifics:
- An [onClose](*key_onClose) callback function is set for the first ad call.
- Every [callback function](*key_callback) possible is specified for the second call and each subsequent call.
- The `onClose` callback function includes code that will be run after the ad unit is closed.
- All errors that occur during the SDK operation or during the execution of callback functions are passed to the [onError](*key_onError) function.
- A `'click'` event handler is assigned to the **Show ads** button (an ad is called on each button click).
```html showLineNumbers
Example of page with SDK configured asynchronously
```
{% endlist %}
[*key_callback]: - `onClose`: Called when the ad is closed, on error, or if the ad failed to open due to too frequent calls. It's used with the `wasShown` argument (`boolean` type), the value of which indicates whether the ad was shown or not.
- `onOpen`: Called when the ad is opened successfully.
- `onError`: Called when an error occurs. The error object is passed to the callback function.
