How to Set Up a Custom Referral and Affiliate Domain

By default, your referral links, affiliate links, and affiliate signup page use oshi.link. With a custom domain, you can use your own branded URL instead — for example, rewards.yourdomain.com. This makes links feel more trustworthy and on-brand when customers and affiliates share them.

Find this under Affiliate Program > Custom Domain in your dashboard.

Setting Up Your Domain

1. Enter Your Domain

Choose a subdomain and base domain combination. For example:

• Subdomain: rewards
• Domain: yourbusiness.com
• Result: rewards.yourbusiness.com

2. Add the DNS Record

After submitting, Oshi displays the CNAME record you need to add with your DNS provider:

Add this record in your DNS provider's settings (e.g., Cloudflare, GoDaddy, Namecheap, Route 53). If you're not sure how, search for your DNS provider's name + "add CNAME record" — most have step-by-step guides.

3. Verify DNS

Once you've added the CNAME record, click Verify DNS Configuration in the dashboard. Oshi checks the record and updates the status:

• Pending DNS — Waiting for CNAME to be configured
• SSL Provisioning — DNS verified, SSL certificate is being provisioned automatically
• Active — Fully operational. Your custom domain is live.

If verification fails, double-check the CNAME record values and wait a bit longer for propagation.

Your Branded Links

Once your domain is active, your links automatically update:

• Referral links: https://rewards.yourdomain.com/{code}
• Affiliate links: https://rewards.yourdomain.com/{code}
• Affiliate signup page: https://rewards.yourdomain.com/affiliate

Existing links using oshi.link continue to work — the custom domain is an additional branded option.

Changing or Removing Your Domain

You can change your custom domain at any time after it's been verified. Click Change to enter a new domain and go through the DNS setup again.

To remove your custom domain entirely, click Remove. Your links will revert to using oshi.link.
