unsubscribe user in payment plugin

Hello Tuan

I created a plugin to subscribe with SMS.
plan = lifetime (until user sends 'stop'), every week user get paid sms.
Everything works smooth.
Only 1 problem:
When user send 'stop' the user need to be removed from the paid group.
I set 'published' to 2 (expired) , but user is still active in the paid group.
I think i need to add some magic code to remove user from the paid group.
I could do this with joomla api , but maybe is there a function 'unsubribe', i can not find that.
any idea?

another question:
if user is expired, the user can create a new subscription i think?

By the way, creating plugins and setting up the component was easy. Me and my customer are very happy

Hi Danny

You can simply trigger onMembershipExpire event. For example, use this code:
$row is a subscription record object.

Regards,

Tuan
