Step 3 : Add payment for the invoice

1. Verify the invoice details by using the Retrieve invoice details API.
2. Use the Retrieve the saved credit/debit cards of a guest API to retrieve the list of saved cards of a guest.
3. Collect payment by using the Add a credit/debit card for a guest API.
4. Use the Insert custom payment for an invoice into Zenoti API to insert the details of a custom payment (which has been collected by using third-party software) for an invoice into Zenoti.
5. If the guest wants to use a new card for payment, use Collect invoice payment by using a guest's unsaved credit/debit card API and complete the payment.
6. Verify whether the invoice has been closed and make sure the payment has been completed successfully by using the Retrieve invoice details API.
7. If the card on file is mandatory and the guest has no saved cards, you can add it using Add a credit/debit card for a guest API.
