Namecheap Setup Guide

Connect your Namecheap account to manage all your domains in Domain Collective.

Namecheap API access requires one of the following:

Note: API access is reviewed manually. Processing time is typically 24-48 hours.

Enable API access for your Namecheap account

Log into your Namecheap account
Navigate to Profile → Tools → API Access
If API access is not enabled:
- Click "Manage" and request API access
- Wait for approval (typically 24-48 hours)
- You'll receive an email when approved

Activate the API once your request is approved

Once enabled, you'll see your API Key displayed on this page.

REQUIRED: Namecheap requires IP whitelisting for security

Namecheap will reject all API requests from non-whitelisted IP addresses. This is a security requirement.

Add your IP address(es):

In the API Access settings, find "Whitelisted IPs"
Add your server's IP address:
- For development: Add your local public IP
- For production: Add your server's static IP address
- You can whitelist multiple IPs (comma-separated)
Click "Save" to apply changes
