All Sitecore configuration get compiled and consolidate in showconfig.aspx file. And this config is the best way to verify default or custom configuration using
https://sc101.cm/sitecore/admin/showconfig.aspx
But recently we were facing configuration issue on CD server since there were no default way to verify showconfig.aspx on content delivery server.
Just to hack this and look showconfig.aspx for content delivery server please follow below steps:
1. Download config click here and save to your instance path wwwroot/sc101.cd
2. From Talend API Tester/Postman, put below input to get output(CD server showconfig.aspx as response) as below screenshot
Method Type: GET
URL: https://YourInstanceName/sitecorecontentdeliveryshowconfig.aspx
Header keys apikey: 464799ae52214c80b7fc81408f8efbe0
Now check your output. Hope this help.
