Understi Uspjeh, Na čekanju i Errili Responses

code: 0 — Uspješno Response Current endpoint examples use code 0 fili successful completed responses.
code: 201 — Na čekanju Order Registracija i transfer documentation can return code 201 when an ilider has been submitted but final processing is still pending.
code: 400 — Request Errili Endpoint examples use code 400 fili request parameter pogreškas.

Registracija Na čekanju Behaviili

Fili domena registration, the current documentation states that a 201 response means the ilider was submitted successfully i the fee was deducted, but final activation is still subject to registry confirmation. Ako the domena cannot be activated, the registration fee is returned to the NiceNIC account balance within 24 hours.

Prenesi Na čekanju Behaviili

The transfer endpoint also documents 201 as a pending ilider. Your application should tovdjefilie treat a pending transfer as accepted fili processing, not as proof that the transfer has already completed.

Pricing

Query Pricing Befilie Paid Operations

NiceNIC's pricing endpoint can retrieve registration, renewal i transfer pricing fili a domena. The documented type values are register, renew, transfer i all. The documented period is 1 to 10 godine, with TLD-specific exceptions possible.
