Custom Domains for Short Links

Take advantage of your highly-recognizable brand and increase conversions while saving characters in SMS messages using Airship-shortened links with a custom domain.

You can replace Airship's standard airsp.co or airsp.eu domains for shortened links with your own custom short link domain. To take advantage of a shortened, custom domain, you must:

  1. Register your short domain name with a Domain Name Registrar.

    Your custom short link domain can include a subdomain, but it cannot include a path.

    • Supported: https://my.site.co
    • Not Supported: https://mysite.co/path
     Note

    While your custom short link domain cannot contain a path, the links that you use in your messages can, of course, contain paths.

  2. Host your domain. Airship supports custom short link domains using HTTP and HTTPS.

  3. Implement a redirect configuration applicable to the web server you use. This document contains instructions for a few common web servers.

  4. Contact Airship to enable your custom short link domain.

When you send an SMS/MMS message from Airship with link shortening enabled:

  • Your end users will receive a shortened link, e.g., http://mysite.co/abcd1234.
  • Your domain must forward http://mysite.co/abcd1234 to https://airsp.co/abcd1234 or https://airsp.eu/abcd1234 (depending on your Airship data center).
  • Airship will handle the final redirect to the full URL that you provided in your original message, e.g., http://myfullsite.com/longURL?query=1234.

Nginx Server Configuration

Use one of the following configurations to redirect your custom short link domain to Airship. The request_uri appended to your custom short link domain — e.g., https://mysite.co/abcd1234 — passes through to Airship's short link domain — e.g., https://airsp.co/abcd1234. Airship then resolves the shortened link, redirecting the user to the original link in your message — e.g., https://myfullsite.com/deals?cart=4321id=0987lkjh.

Redirect only HTTP traffic from your custom short link domain to Airship.
server {
    listen 80;
    
    location / {
      return 303 https://airsp.co$request_uri;
    }
}
Redirect both HTTP and HTTPS traffic from your custom short link domain to Airship.
server {
    listen 80;
        
    location / {
        return 303 https://airsp.co$request_uri;
    }
}

server {
    listen 443 ssl;
    ssl on;
    ssl_certificate  /etc/nginx/ssl-certs/airsp.crt;
    ssl_certificate  /etc/nginx/ssl-certs/airsp.key;

    location / {
        return 303 https://airsp.co$request_uri;
    }
}

Apache Server Configuration

Use one of the following configurations to redirect your custom short link domain to Airship. The request_uri appended to your custom short link domain — e.g., https://mysite.co/abcd1234 — passes through to Airship's short link domain — e.g., https://airsp.co/abcd1234. Airship then resolves the shortened link, redirecting the user to the original link in your message — e.g., https://myfullsite.com/deals?cart=4321id=0987lkjh.

Redirect only HTTP traffic from your custom short link domain to Airship.

If the mod_rewrite module is enabled, add the following lines to your sites-available/000-default.conf file.

<VirtualHost *:80>
    ... (other .conf code)...
    <Location />
        Redirect 303 https://airsp.co%{REQUEST_URI}
    <Location>
</VirtualHost>
Redirect both HTTP and HTTPS traffic from your custom short link domain to Airship.

In your sites-available/default-ssl.conf file, add a Location directive block containing the following:

<VirtualHost _default_:443>
  ... (other .conf code)...

  <Location />
      Redirect 303 https://airsp.co%{REQUEST_URI}
  </Location>
</VirtualHost>

In your sites-available/000-default.conf file add the following two lines. This assumes that the mod_rewrite module is enabled for your server.

<VirtualHost *:80>
    ... (other .conf code)...
    <Location />
        Redirect 303 https://airsp.co%{REQUEST_URI}
    <Location>
</VirtualHost>

Microsoft IIS Configuration

Use the following configuration to redirect your custom short link domain to Airship. The request_uri appended to your custom short link domain — e.g., https://mysite.co/abcd1234 — passes through to Airship's short link domain — e.g., https://airsp.co/abcd1234. Airship then resolves the shortened link, redirecting the user to the original link in your message — e.g., https://myfullsite.com/deals?cart=4321id=0987lkjh.
