# How to extend a license subscription from a URL

You can extend a license subscription by invoking the *RenewSubscriptionHttp* method as follows:

<http://yourserver.com/qlm/qlmservice.asmx/RenewSubscriptionHttp?is\\_avkey=ABC-DEF-GHI\\&is\\_expduration=\\><duration>\&is\_expdate=\<yyyy-mm-dd>

You can set one and only one of the expiry arguments: is\_expdate or is\_expduration.

When setting the *is\_expdate* argument, the expiry date is absolute. The new expiry date will be set to the date you specified regardless of the previous value.

When setting the *is\_expduration* argument, the expiry date is incremental. The new expiry date will be set to the previous value plus the new duration.

**Examples:**
