Frequently Asked Questions
1) What is the NiceNIC Reseller API v2?
API v2 is NiceNIC's updated REST-style interface that lets resellers automate all domain lifecycle actions—registration, transfer, renewal, WHOIS modification, and DNS management—through secure HTTPS requests and JSON responses.
2) How is API v2 different from the older API?
Version 2 offers faster response speed, simplified authentication, improved error handling, and full JSON-based output instead of legacy query strings. It's designed to be easier to integrate with modern applications and frameworks.
3) How can I get API credentials?
After you become a verified reseller, log in to your dashboard and visit the "API Settings" section. There you can generate an API Key and Secret Token to start sending authenticated requests immediately.
4) What can I do with the API?
You can search domain availability, register new domains, renew existing ones, transfer domains using EPP codes, update WHOIS information, manage DNS records, check account balance, and query domain status — all without logging in manually.
5) Which programming languages are compatible?
Any language that supports HTTPS requests works with the API. Developers typically use PHP (with cURL), Python (requests), Node.js (axios or fetch), or Java. Example scripts in PHP are published directly on this page.
6) Does NiceNIC provide a sandbox or demo mode for testing?
Yes. You can test the API freely in the demo environment before switching to the live production endpoint. The sandbox simulates real domain transactions but does not create or charge live orders.
7) How is security enforced in API v2?
All requests must use HTTPS and valid API credentials. IP whitelisting can be configured to restrict access to your servers. Tokens are encrypted, and rate limiting is used to protect both users and the registrar network.
8) What are the most common API commands available?
Typical endpoints include:
domain-register for new registrations
domain-transfer for inbound transfers
domain-renew for renewals
domain-info for WHOIS lookup
dns-modify for nameserver or record updates
account-balance for checking reseller credits
9) What should I do if an API request fails?
The API returns a clear error code and message in JSON format. Common issues include invalid credentials, unauthorized IPs, or incorrect parameters. Review the response message or contact our support team with the request log for quick troubleshooting.
10) Where can I find detailed documentation and sample code?
All endpoint references, parameters, authentication samples, and PHP demo scripts are available directly on http://www.unionroom.cn/reseller/apiv2.php. You can also access support 24/7 for integration questions through the reseller helpdesk.
