Hi,
I am new to Apex and we are currently using Apex 5.1. I have the need to call an external ReST-based web service residing inside our firewall using http (not https). It's a simple GET request which either returns HttpStatus.OK (for success) or HttpStatus.INTERNAL_SERVER_ERROR (for failure). An example of the GET request is as follows:
GET http://servername:port/GDD2232/20181010
What are the ways to invoke (consume) this external ReST-based web service from APEX 5.1?
Thank you for any information.
Sunil
