By default, for all API users auto-renewal is ON.
It means that Veryfi charges the Card we have on file for all your renewal invoices automatically.
While there is no option to update Credit Card information on a user side, no worries, this will be added soon. In the meantime, in case if you would like to update Credit Card information, please contact firstname.lastname@example.org.
We will send you the direct link to Stripe Payment Page, where you can insert new Credit Card details, instead of charging the current Card we have on file.
Once updated, new Credit Card details will be used for all next renewal invoices, unless you need to update it again.
