Subscription event hooks and recurring payments

-- HikaShop version -- : 4.6.1
-- HikaSerial version -- : 4.0.1
-- Joomla version -- : 4.1.4
-- PHP version -- : 8.0

Hi

I'm considering a use case where I would need to modify the price of a recurring subscription "on the fly". Let me explain.
A user signs up to a monthly subscription. I would like to create a plugin that checks the subscription before a recurring payment and in some cases (defined by code in the plugin) lowers the monthly payment.

I can code the plugin and the needed logic, but do we have any event hooks in Hikashop/Hikaserial that the plugin can use for changing the recurring payment amount? E.g. onBeforeSubscriptionUpdate?

Thanks

Hello,

Modifying a price is possible since you have various triggers in HikaSerial and HikaShop.
But the real problem I see is regarding the payment platform ; because if you want to change the recurring price, it means that the payment plugin would be able to accept a modification in the reccuring price.

Regards,
