# 4. Process payment result

How you obtain the payment result varies depending on how the payment window is loaded. In a typical PC environment, the payment window is loaded into an iframe, and in a mobile environment, it is loaded by redirecting to a new page.

When the payment process is completed successfully, you can receive the payment result based on the payment window type as follows:

|         iframe        |         Popup        |
| :-------------------: | :------------------: |
| **callback function** | **m\_redirect\_url** |

Refer to the following detailed instructions:

{% content-ref url="/pages/hIvjyBkT4StrhPqlQQQQ" %}
[Iframe method](/docs-en/auth/guide/4./iframe.md)
{% endcontent-ref %}

{% content-ref url="/pages/6nVBG1BMGjNTJeAIc4Ws" %}
[Redirect method](/docs-en/auth/guide/4./redirect.md)
{% endcontent-ref %}
