Detecting language please wait for.......
I'd like to check what I can do from Rest API(or Web service API) on SDL Tridion Docs. Where can I find such API descriptions?
The Web service API documentation can be found here.
There is currently no REST API for Tridion Docs Content Manager.
You can programatically access information from Tridion docs by using their SOAP API (there is no REST API). Their API for Tridion uses WSDL files that are available from their endpoints. WSDL files describe how to format the request as well as what operations are available on a web service (aka tridion SOAP api ).
Instead of doing it manually, (which is possible), I recommend using DotNet to automate most of it for you.
You can find example of how to authenticate under
Documentation -> Trodion docs -> Implementing SDL Tridion Docs -> Content Manager API -> Web services sample
or use the link below: https://docs.sdl.com/LiveContent/web/pub.xql?action=home&pub=SDL%20Tridion%20Docs-v2.1.1&lang=en-US#docid=GUID-EF279428-A1C0-40D9-9DE1-EB2CA8CCFB51&addHistory=true&query=&scope=&tid=&filename=GUID-31BD6A3E-62C7-4486-80D0-B8E1CB841840.xml&resource=&inner_id=&toc=false&eventType=lcContent.loadDocGUID-EF279428-A1C0-40D9-9DE1-EB2CA8CCFB51
Essentially, you are sending a XML request to your application's endpoints. XML has to formatted according to WSDL files (however WSDL files aren't going to fully describe it) so you'll need the libraries.
https://github.com/sdl/ISHRemote is a working implementation of the Tridion Docs WCF WS-Trust-authenticated SOAP API. So working example code.
