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:

/RenewSubscriptionHttp?is_avkey=BDHD0-X0K00-G5AK6-I8W4J-1Q1AKMAHN&is_expduration=90
