Testing subscription renewals on Stripe

php stripe-payments payment webhooks subscriptions

Our solution was to reset the billing cycle of the subscription.

open the subscription in Stripe
click "Actions" in the upper right
select "Update Subscription"
be sure to switch off "Prorate changes"
scroll down and open "Advanced Options"
check "Reset billing cycle"
and finally... Update Subscription

This will trigger a new subscription payment and all the associated webhooks.
