Here's a document giving more information on this.
It is not possible to send a payment link for a specific invoice alone, sorry.
You could send the customer an update payment method link to add/update their card details. Once updated, the card details will be stored in the payment gateway's vault and the last 4 digits will be stored in Chargebee.
In your case, you could send the customer the link so that they can add their card details and then use the 'collect now' option on the invoice to collect the payment from the customer.
The payment method link can be sent to the customer from the Chargebee web interface under Subscriptions -> Send Email -> Mail Templates -> Request payment method details.
Hope this helps.
