I have create functionality on event "**sales\_order\_place\_after**".
I have to Send "**COUPON CODE**" for an order placed with this event "**sales\_order\_place\_after**". If someone does fail credit card transaction then also this "**COUPON CODE**" was sent. This is wrong.

And also order created with "Canceled" on 

> 
> admin->sales->orders
> 
> 
> 

.
Can you suggest me any event for success order only?
