How to modify API URL?

Issue

• If we are removing the /o/ from URLs, they are not recognised anymore.

Environment

• Liferay DXP 7.1+

Resolution

• You can create a hostname e.g. api.something.com and have Apache (or Nginx) do the proxy pass to Liferay with /o.
   
  Below is a sample configuration could be implemented e.g. on localhost
   
  httpd.conf extract:
   
  

  <VirtualHost *:80>
      ServerName api.localhost
  
      ProxyTimeout 300
      ProxyRequests on
      ProxyPreserveHost On
  
      <Location />
          ProxyPass http://localhost:8080/o/
          ProxyPassReverse http://localhost:8080/o/
      </Location>
  
  </VirtualHost>

   
  With this setting API can be accessed as the following URL:
   
  http://api.localhost/headless-delivery/v1.0/sites/20121/content-elements
   
  Instead of http://localhost:8080/o/headless-delivery/v1.0/sites/20121/content-elements
