Core Concepts

Domain Portfolio

Your domain portfolio contains all domains registered under your Hostinger account. Each domain has configuration for nameservers, WHOIS contacts, lock status, and privacy protection.

Domain Availability

Before purchasing, check if a domain name is available across one or more TLDs. The API also supports alternative domain suggestions.

Domain Forwarding

Redirect a domain to another URL using 301 (permanent) or 302 (temporary) redirects.

WHOIS Profiles

Contact information associated with domain registrations. Each TLD may require specific WHOIS details. Profiles can be reused across multiple domains.

Domain Lock

Prevents unauthorized domain transfers. Must be disabled before transferring a domain to another registrar.

Privacy Protection

Hides the domain owner's personal information from public WHOIS databases.

Domain Access Verification

Some operations require proof that you control a domain. The Domain Access Verifier returns the pending and completed verifications for a set of domains, so you can check verification status before relying on a domain.

Note: This endpoint lives under a different base path — /api/v2/direct/verifications/active — not /api/domains/v1/.

Common Patterns

Check Domain Availability

curl -X POST "https://developers.hostinger.com/api/domains/v1/availability" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "domain": "myawesomesite",
    "tlds": ["com", "net", "org"],
    "with_alternatives": true
  }'

Python SDK:

from hostinger_api import Hostinger

client = Hostinger(api_token="YOUR_API_TOKEN")
result = client.domains.availability.check(
    domain="myawesomesite",
    tlds=["com", "net", "org"],
    with_alternatives=True
)

TypeScript SDK:

import { Hostinger } from "hostinger-api-sdk";

const client = new Hostinger({ apiToken: "YOUR_API_TOKEN" });

const result = await client.domains.availability.check({
  domain: "myawesomesite",
  tlds: ["com", "net", "org"],
  withAlternatives: true,
});

PHP SDK:

use Hostinger\Api\HostingerApi;

$client = new HostingerApi('YOUR_API_TOKEN');

$result = $client->domains->availability->check([
    'domain' => 'myawesomesite',
    'tlds' => ['com', 'net', 'org'],
    'with_alternatives' => true,
]);

Note: Rate limited to 10 requests per minute. TLDs should be without leading dot (e.g., com not .com). For alternatives, provide only one TLD.

Purchase a Domain

curl -X POST "https://developers.hostinger.com/api/domains/v1/portfolio" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "domain": "my-new-domain.com",
    "item_id": "hostingercom-domain-com-usd-1y",
    "payment_method_id": 1327362,
    "domain_contacts": {
      "owner_id": 741288,
      "admin_id": 741288,
      "billing_id": 741288,
      "tech_id": 741288
    }
  }'

Get item_id from the billing catalog. If no payment method is provided, your default is used. If no WHOIS info is provided, default contact information for that TLD is used.

Best Practices

Registration

• Always check availability before attempting to purchase
• Ensure WHOIS profile exists for the target TLD before registering
• Some TLDs require additional_details — check requirements per TLD
• Keep domain lock enabled to prevent unauthorized transfers

Security

• Enable privacy protection to hide personal information from public WHOIS
• Enable domain lock on all production domains
• Only disable domain lock immediately before an intended transfer

Nameservers

• Improper nameserver configuration makes the domain unresolvable
• Always have at least 2 nameservers configured
• Verify nameservers are responding before switching

Forwarding

• Use 301 (permanent) for SEO-preserving redirects
• Use 302 (temporary) for short-term redirects
• Remove forwarding before pointing the domain to hosting

Troubleshooting

Domain Not Resolving After Nameserver Change

• Nameserver changes can take up to 48 hours to propagate
• Verify new nameservers are configured correctly: dig NS example.com
• Check that DNS records exist on the new nameserver

Domain Purchase Failed

• Check registration status in hPanel
• Verify WHOIS profile is complete for the target TLD
• Ensure payment method has sufficient funds

Domain Lock Cannot Be Disabled

• Some TLDs have registrar-imposed lock periods after registration
• Contact support if the lock state doesn't change

WHOIS Profile Deletion Fails

• Profile may be in use by active domains
• Check usage with the /whois/{whoisId}/usage endpoint first
