I have just discovered that passing customer_id to a payment link does nothing.
It returns a new client instead. This way I cannot differentiate, who has purchased subscription originally because I need to mark my customers with internal ID. So first I create a customer, then I need to create a payment link for them.
Is it even possible? If not, how do I assign a subscription with specific metadata to a client with specific metadata which was created before?
