Prerequisites
• ThingWorx is enabled to allow import of Windchill extension.
The import of extension is disabled in ThingWorx for all users by default. To enable import, configure the platform-settings.json file. For more information see platform-settings.json Configuration Details in the ThingWorx Platform Help Center.
1. Open the platform-settings.json file. By default, the file is located in the ThingworxPlatform folder.
2. Add or update the following ExtensionPackageImportPolicy parameters to true to allow import of extensions.
|
|
All parameters are set to false by default. Reference platform-settings.json for more information about each parameter. |
"ExtensionPackageImportPolicy": {
"importEnabled": false,
"allowJarResources": false,
"allowJavascriptResources": false,
"allowCSSResources": false,
"allowJSONResources": false,
"allowWebAppResources": false,
"allowEntities": false,
"allowExtensibleEntities": false
},
3. Save and close the platform-settings.json file.
To know about best practices on configuration, see Importing Extensions in the ThingWorx Platform Help Center.

Refer to the documentation for your supported version of ThingWorx application.

• ThingWorx is configured to allow Cross-Origin requests.
Add a Cross-Origin Resource Sharing (CORS) filter to the ThingWorx Flow server to enable Cross-Origin requests. This setting will allow external OSLC server to access data from the ThingWorx Flow server.
Complete the following steps to enable a website to make a REST call to ThingWorx Flow:
1. Shut down any running Nginx instances.
2. Open the vhost-flow.conf file from the following location in Nginx installation directory.
▪ Windows: C:/Program Files/nginx-<version>/conf/conf.d
▪ Linux: /etc/nginx/conf/conf.d
3. In the vhost-flow.conf file, under the location /Thingworx section, locate the proxy_set_header X-Content-Type-Options nosniff; line, and add the following lines:
set $cors '';
# Right side of condition can be regular expression:
# if ($http_origin ~ '^https?://(localhost|www\.yourdomain\.com|www\.yourotherdomain\.com)')
if ($http_origin = '<Origin_that_calls_ThingWorx_Flow>') {
set $cors 'true';
}
if ($cors = 'true') {
add_header 'Access-Control-Allow-Origin' "$http_origin" always;
add_header 'Access-Control-Allow-Credentials' 'true' always;
}
# OPTIONS indicates a CORS pre-flight request
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '$http_origin';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
4. Replace <Origin_that_calls_ThingWorx_Flow> with the URL of the website that is trying to access ThingWorx Flow.
5. Restart the Nginx service.
To know more about the Cross-Origin Resource Sharing (CORS) setting, see Making a REST Call from an External Website to ThingWorx Flow in the ThingWorx Platform Help Center.

• Windchill server is added as a secured domain in allow list of OSLC servers.
Add
Windchill as a secured domains in OSLC servers configured with
Windchill RV&S,
Windchill Modeler, and
IBM Rational Doors NG, to enable access to the delegated interface from
Windchill. For more information about how to add domains as secured, see the
Windchill RV&S OSLC Server guide (12.3.0.0 onwards) on
Reference Documents,
OSLC integration with Integrity Modeler and
OSLC integration with IBM Rational DOORS Next Generation in the
Windchill Modeler Help Center.
