Before an invoice is finalised, you're able to add the custom_fields when invoice is still in draft state: https://stripe.com/docs/api/invoices/create#create_invoice-custom_fields

[slim pivot]

is there a way to pass them when creating a subscription. so that these values can be used in all upcoming invoices

custom_fields can't be set at subscription level. Two ways I can think of:

1. Listen to invoice.created event and update the custom_fields while invoice is still in draft: https://stripe.com/docs/api/invoices/update#update_invoice-custom_fields
2. Set the invoice_settings.custom_fields at Customer level and it'll apply to all invoices for the customer: https://stripe.com/docs/api/customers/update#update_customer-invoice_settings-custom_fields

[slim pivot]

okay. so each invoice should be updated if i want the custom fields to persist. Stripe can't persist the custom fields in next invoice by itself. right ?

[solemn lion]

Yup! It's not possible with subscription invoices unless custom_fields is set at Customer level

[slim pivot]

if we want to use custom fields at customer level, can we make them have dynamic values based on subscription metadata?

[solemn lion]

That's not supported
