Do you mean "does" have low balance issues?

[swift gate]

yes

if the attached bank account has not much balance to fulfil the subscription amount then what would happen?

[slender river]

The subscription would attempt to charge, and if it fails the subscription will go to a past_due status until it can be paid. At that point, it'll follow the retry rules you have set in your dashboard at https://dashboard.stripe.com/settings/billing/automatic (under the "manage failed payments" section)

[swift gate]

can I call the webhook for this problem?

[slender river]

Yup!

You'd listen for the customer.subscription.updated event and check the status, or you could listen for the invoice.payment_failed event to know when payment has failed
