Admin ResellerClub settings

These settings are for platform administrators only. They define the default ResellerClub (e.g. ColoDNS) credentials used when a reseller creates a server and does not use their own ResellerClub account. New servers then get hostname and nameservers on the configured base domain (e.g. {vmi}.colodns.com, {vmi}ns1.colodns.com, {vmi}ns2.colodns.com).

Where to find it

In the admin panel: Extensions (or Server Manager) → ResellerClub (colodns.com) settings (route: servermanager/settings).

Fields

• Base domain – e.g. colodns.com. Hostnames are {vmi}.base_domain, {vmi}ns1.base_domain, {vmi}ns2.base_domain.
• ResellerClub Reseller ID – Your ResellerClub reseller ID.
• ResellerClub API Key – API key from ResellerClub. Leave blank to keep the existing stored key.
• colodns.com Order ID (optional) – Leave blank to look up the order ID by base domain (ResellerClub domains/orderid). Or enter the order ID for your base domain.

Server outbound IP

The page shows the Server outbound IP – the IP address that ResellerClub sees when the server makes API requests. You must whitelist this exact IP in ResellerClub → Settings → API. If the IP is not whitelisted, the API returns HTTP 403 and Test connection (and DNS creation) will fail. After adding or changing the whitelist, wait 30–60 minutes before testing again.

Save settings and Test connection

Use Save settings to store the credentials. Use Test connection to verify:

• The platform sends a ResellerClub API request (using saved base domain and optional order ID; if order ID is blank, it looks up order ID by base domain).
• On success: green indication and a copyable success message.
• On failure: red indication and a copyable error message (e.g. 403 – whitelist Server outbound IP and wait 30–60 min).

The result is shown in a textarea with a Copy to clipboard button so you can share or log the message.

Reseller override

Resellers can use their own ResellerClub credentials in Server Manager → DNS or Reseller settings by enabling “Use my own ResellerClub account” and entering their Reseller ID, API key, and optional Order ID. When set, their credentials are used for their servers instead of these admin settings.
