How do I get subscription key or id using Woocommerce subscriptions?

patrick

To switch to a custom function I need to get the subscription key of a particular subscription. I referenced the documentation where it shows how to get the key, but I failed to include it in my code. So what my code does is I hook in processed subscription payment with my function when a renewal is triggered. So this code only runs when you pay for a subscription renewal.

add_action( 'processed_subscription_payment', 'callupdater' );

function callupdater()
{
    //need to get the subscription key here to pass to updatedays()
    $key = .....
    updatedays(key);
}

function updatedays($subscription_key)
{
    //do some tasks with the key
}

Please help

After spending a few minutes I got the solution for this please look the code below

add_action( 'processed_subscription_payment', 'updatedays', 10, 2 );

function updatedays($user_id, $subscription_key)
{  
    //do what I need to the sub key
}
