Registering Handles on private domains AND not paid with FIO
If cart contains a domain (meaning the domain is not yet registered) and a single handle(s) on that domain:
The registration should be performed using the /register_fio_domain_address call.
If cart contains multiple handles on a new domain or 1 or more handle on an existing private domain:
If owner wallet is a Ledger Wallet registration of FCH on private domain is not allowed
Display error: “At this moment registration of FIO Handles on private domains secured by Ledger device are only supported when paid for using FIO Tokens.”
Have the user sign a transaction registering that FCH using pay with FIO functionality
Set the
max_feeparameter to 125% of fee obtained from get_fee forregister_fio_address
Once payment is received (e.g. webhook notification from Stripe received):
If domain is being registered in the same purchase, register it first
If registration fails, automatically fail FCH registrations on that domain
Wait at least 5 seconds between registering the domain and first handle on that domain
Re-check current
register_fio_addressfeeIf just obtained
register_fio_addressis more than the fee signed by user in the step above fail FCH registration
Send FIO Tokens to user in the amount of just obtained
register_fio_addressIf transaction fails with
Insufficient funds to cover fee:re-check current
register_fio_addressfeeSend users the difference between new fee and number of tokens they received
Resubmit the transaction with higher fee
Registering or renewing domains for multiple years
If cart contains a domain registration or renewal for more than 1 year, it will be captured as a single cart item, but needs to be executed sequentially as follows:
Register 2+ years
First call is register_fio_domain
For each additional year execute renew_fio_domain
Renew 2+ years
For each year of renewal execute renew_fio_domain
On errors:
If first call fails, the entire item fails, Shopping and Checkout | Purchase Error error message is shown and appropriate form of payment refund is processed (Stripe, Bitpay).
If 2nd or later call fails, the item needs to be modified as follows:
Original item is modified to reflect what was purchased
New item is added to reflect what fails
Example:
User wants to buy a domain for 3 years
1st register_fio_domain is sucesful
2nd renew_fio_domain fails
Original item (“FIO Domain Registration - 3 years”) is modified to “FIO Domain Registration - 1 year” and marked as Success
New item is created: FIO Domain Renewal - 2 years and is marked Failed
The overall order is marked Partial Success, Shopping and Checkout | Partial Success error messages is shown and appropriate form of payment refund is processed (Stripe, Bitpay)
Analytics and Reporting
There is no change to analytics or reporting
Register/renewal for 1 year shows up the same as multi-year, except the value will be higher.
