Make sure that the 3CX server is installed and activated

1. Upload files


Create C:\Program Files\3CX Phone System\Bin\webapi


Download link https://download.creomate.com/webapi_win_en.zip


Place files in a folder:

  • TCXWebAPI.exe
  • ffmpeg.exe
  • TCXWebAPI.ini
  • 3cxpscomcpp2.dll
  • tcxpscom_native.dll
  • sl.dll
  • AuthKeys.csv
  • TCXWebAPI.ini
  • AllowedIP.txt


Create C:\Program Files\3CX Phone System\Bin\webapi\mp3 (for MP3 records) 


Don't forget to grant write permissions C:\Program Files\3CX Phone System\Bin\webapi\


2. Create Windows Service WebAPI


Execute in command shell (not PowerShell) as Administrator:


sc create webapi binpath= "\"C:\Program Files\3CX Phone System\Bin\webapi\TCXWebAPI.exe\" --urls=http://127.0.0.1:8081" displayname= "3CX WebAPI" start= auto obj= "NT AUTHORITY\LocalService"



Start WebAPI Service


sc start webapi


Stop WebAPI Service


sc stop webapi


Delete WebAPI Service


sc delete webapi



3. Edit NGINX.conf file (must be performed after each update 3CX)


C:\Program Files\3CX Phone System\Bin\nginx\conf\nginx.conf (the file is write protected)


After:

 client_max_body_size 300m;
 root "C:/ProgramData/3CX/Data/Http/wwwroot";


Add:

location ~ ^/webapi/?(.*) 
{
include "shared-headers.conf";
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8081/webapi/$1$is_args$args;
proxy_buffering off;
proxy_read_timeout 300;
proxy_connect_timeout 300;
proxy_send_timeout 300;

}


Restart nginx Service (3CX Phone System Nginx Webserver)

sc stop nginx
sc start nginx



4. Checking


http://127.0.0.1:8081/webapi/tcx


From public network:

https://{fqdn and port 3СХ Phone}/webapi/tcx



5. Activate a license


https://{FQDN and port 3СХ}:5001/webapi/admin/


login - TCXWebAPI
password- Activate (after activation will be license XXXX-XXXX)


For trial activation use NHQE-QRND-TRIAL (only once)


6. Enjoy :-)
