With the White Label solution you are able to run the QR Code manager platform of qrd°by under your own sub domain. All QR Codes will be encoded with your domain, you can create user accounts under your domain and you can brand the platform with your own logo, name and colors. Users will not see any sign or hint that the service is hosted by qrd.by.
A branded white label instance for a customer with a custom domain
To unlock your White Label instance, just enter your sub domain name (e.g.
qr.mydomain.com) in the branding section (Hint: A shorter domain name, will create QR Codes that may be printed in a smaller size, since less characters are encoded).
Set your desired domain name in the branding section
Make sure that you are the owner of the domain and that you created your chosen sub domain (e.g.
qr) at your registrar before. In the created sub domain create a CNAME-Record that points to the URL
It may take up to 24 hours until your CNAME-Record will be published by your registrar to all name servers.
Until your subdomain has not been propagated to all name servers, you will not be able to change the production domain in your account.
How to setup a sub domain and a CNAME-Record
The following figures and tutorials are based on our domain provider Domaindiscount24. He allows almost any RFC conform DNS configuration. You can create unlimited subdomains or wildcard domains and set any TXT or CNAME entry.
In the following figures you see how to create a sub domain
qr and set a CNAME-Record for your white label platform.
Caution: do not use ‘www’ as subdomain
In the domain manager select your domain and create a sub domain for it:
Under CNAME-Settings on your created sub domain add the CNAME-Record
qr.webapp-portal.com. This entry links your sub domain with our portal.
Create a CNAME record
How to verify your CName-Record
Depending on your registrar, it may take up to 24 hours until the domain really points to our server. If you experience problems setting a CNAME-Record please contact your hosting partner or registrar.
To check if your CNAME entry was successful, simply do a nslookup for your chosen sub domain and see if the result includes the CNAME URL
You can also use the online web interface https://www.digwebinterface.com to check from different DNS Servers if your CNAME entry has been distributed. Just enter your custom domain in the Hostname window, select CNAME as the type and click on “Dig”. You should see your domain pointing to
qr.webapp-portal.com at the bottom.
Note: Do NOT use A-Records
A-Records are not supported, since we have multiple IP addresses in our cloud for load balancing.The IP for your white label instance might changes over time.
Note: Do NOT use a Redirect or Forward
Do not use a forward or redirect. Your domain will not be recognized by our servers.
Note: Do NOT use CNAME Records in the Root Domain
CNAME’ing a root record (e.g.
mydomain.com) is technically not against RFC, but does have limitations, meaning it is a practice that is not recommended. Normally your root record will have multiple entries (e.g. name servers and an IP address)
Per RFC: If a CNAME record is present at a node, no other data should be present.
Once you successfully setup your custom domain, we will add an SSL certificate to your domain within the next 48 hours.
