Returns a hex encoded hash of the machine id and the currently logged in user name. This is the recommended way to uniquely identify a user / machine combination.
For Windows systems this is a sha256 hash of the machine ID set in the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid and USERNAME.
For OSX systems, a native-level call is used to get the machine ID.
fin.System.getUniqueUserId().then(id => console.log(id)).catch(err => console.log(err));
Returns information about the given app's certification status
Runs an executable or batch file. A path to the file must be included in options.
A uuid may be optionally provided. If not provided, OpenFin will create a uuid for the new process.
Note: This method is restricted by default and must be enabled via
API security settings. Also, this api has an enhanced permission set to make it less dangerous. So application owners can only allow to launch the assets owned by the application, the enabled downloaded files or the restricted executables.
A object that is defined in the ExternalProcessRequestType interface
If an unused UUID is provided in options, it will be used. If no UUID is provided, OpenFin will assign one. This api has an enhanced permission set to make it less dangerous. So application owners can only allow to launch the assets owned by the application, the enabled downloaded files or the restricted executables.
Note: Since appAssets relies on the RVM, which is missing on MAC_OS, 'alias' is not available. Instead provide the full path e.g. /Applications/Calculator.app/Contents/MacOS/Calculator.
Basic Example:
fin.System.launchExternalProcess({
path: 'notepad',
arguments: '',
listener: function (result) {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
Promise resolution:
//This response has the following shape:
{
uuid: "FB3E6E36-0976-4C2B-9A09-FB2E54D2F1BB" // The mapped UUID which identifies the launched process
}
Listener callback:
//This response has the following shape:
{
topic: "exited", // Or "released" on a call to releaseExternalProcess
uuid: "FB3E6E36-0976-4C2B-9A09-FB2E54D2F1BB", // The mapped UUID which identifies the launched process
exitCode: 0 // Process exit code
}
By specifying a lifetime, an external process can live as long the window/application that launched it or persist after the application exits. The default value is null, which is equivalent to 'persist', meaning the process lives on after the application exits:
fin.System.launchExternalProcess({
path: 'notepad',
arguments: '',
listener: (result) => {
console.log('the exit code', result.exitCode);
},
lifetime: 'window'
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
Note: A process that exits when the window/application exits cannot be released via fin.desktop.System.releaseExternalProcess.
By specifying a cwd, it will set current working directory when launching an external process:
fin.System.launchExternalProcess({
path: 'cmd.exe',
cwd: 'c:\\temp',
arguments: '',
listener: (result) => {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
Example using an alias from app.json appAssets property:
"appAssets": [
{
"src": "exe.zip",
"alias": "myApp",
"version": "4.12.8",
"target": "myApp.exe",
"args": "a b c d"
},
]
// When called, if no arguments are passed then the arguments (if any)
// are taken from the 'app.json' file, from the 'args' parameter
// of the 'appAssets' Object with the relevant 'alias'.
fin.System.launchExternalProcess({
//Additionally note that the executable found in the zip file specified in appAssets
//will default to the one mentioned by appAssets.target
//If the the path below refers to a specific path it will override this default
alias: 'myApp',
listener: (result) => {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
Example using an alias but overriding the arguments:
"appAssets": [
{
"src": "exe.zip",
"alias": "myApp",
"version": "4.12.8",
"target": "myApp.exe",
"args": "a b c d"
},
]
// If 'arguments' is passed as a parameter it takes precedence
// over any 'args' set in the 'app.json'.
fin.System.launchExternalProcess({
alias: 'myApp',
arguments: 'e f g',
listener: (result) => {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
It is now possible to optionally perform any combination of the following certificate checks
against an absolute target via fin.desktop.System.launchExternalProcess():
"certificate": {
"serial": "3c a5 ...", // A hex string with or without spaces
"subject": "O=OpenFin INC., L=New York, ...", // An internally tokenized and comma delimited string allowing partial or full checks of the subject fields
"publickey": "3c a5 ...", // A hex string with or without spaces
"thumbprint": "3c a5 ...", // A hex string with or without spaces
"trusted": true // A boolean indicating that the certificate is trusted and not revoked
}
Providing this information as part of the default configurations for assets in an application's manifest will be added in a future RVM update:
fin.System.launchExternalProcess({
path: 'C:\\Users\\ExampleUser\\AppData\\Local\\OpenFin\\OpenFinRVM.exe',
arguments: '--version',
certificate: {
trusted: true,
subject: 'O=OpenFin INC., L=New York, S=NY, C=US',
thumbprint: '3c a5 28 19 83 05 fe 69 88 e6 8f 4b 3a af c5 c5 1b 07 80 5b'
},
listener: (result) => {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
It is possible to launch files that have been downloaded by the user by listening to the window
file-download-completed event and using the fileUuid provided by the event:
const win = fin.Window.getCurrentSync();
win.addListener('file-download-completed', (evt) => {
if (evt.state === 'completed') {
fin.System.launchExternalProcess({
fileUuid: evt.fileUuid,
arguments: '',
listener: (result) => {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => {
console.log(processIdentity);
}).catch(error => {
console.log(error);
});
}
});
Launching assets specified in the app manifest:
Sample appAssets section in app.json
"appAssets": [
{
"src": "http://filesamples.com/exe.zip",
"alias": "myApp",
"version": "4.12.8",
"target": "myApp.exe",
"args": "a b c d"

}
]
This permission allows for launching of all assets specified in the above appAssets section. ("myApp" and "myApp2"):
"permissions": {
"System": {
"launchExternalProcess": {
"enabled": true,
"assets": {
"enabled": true
}
}
}
}
This permission allows for launching of only the "myApp" asset in the above appAssets section, as defined in srcRules:
"permissions": {
"System": {
"launchExternalProcess": {
"enabled": true,
"assets": {
"enabled": true

}
}
}
}
Launching downloaded files:
"permissions": {
"System": {
"launchExternalProcess": {
"enabled": true,
"downloads": {
"enabled": true
}
}
}
}
This permission allows to launch all the executables:
"permissions": {

ExperimentalLaunch application using a manifest URL/path. It differs from Application.startFromManifest in that this API can accept a manifest using the fin protocol.
The manifest's URL or path.
Parameters that the RVM will use.
Supports protocols http/s and fin/s, and also a local path.
Note: This API is Windows only.
This API can handle most manifest types. Some examples below.
Traditional:
const manifest = await fin.System.launchManifest(
'https://demoappdirectory.openf.in/desktop/config/apps/OpenFin/HelloOpenFin/app.json');
console.log(manifest);
Platform:
const manifest = await fin.System.launchManifest('https://openfin.github.io/platform-api-project-seed/public.json');
console.log(manifest);
Launching traditional manifest into a platform:
const manifest = await fin.System.launchManifest(
'https://openfin.github.io/platform-api-project-seed/public.json?\
$$appManifestUrl=https://demoappdirectory.openf.in/desktop/config/\
apps/OpenFin/HelloOpenFin/app.json');
console.log(manifest);
Launching with RVM options:
const manifest = await fin.System.launchManifest('https://openfin.github.io/platform-api-project-seed/public.json',
{ noUi: true, userAppConfigArgs: { abc: '123', xyz: '789' } });
console.log(manifest);
Local Path:
const manifest = await fin.System.launchManifest('file://c:\\path\\to\\manifest\\file.json');
console.log(manifest);
Launching with RVM 'subscribe' option:
This option allows users to subscribe to app version resolver events when calling launchManifest with fallbackManifests specified.
fin.System.launchManifest('fins://system-apps/notifications/app.json', { subscribe: (launch) => {
launch.on('app-version-progress', (progress) => {
console.log("Trying manifest " + progress.manifest)
});
launch.on('runtime-status', (status) => {
console.log("Runtime status: " + JSON.stringify(status));
});
// RVM has successfully found the target runtime version
launch.on('app-version-complete', (complete) => {
console.log("Parent app " + complete.srcManifest + " resolved to " + complete.manifest);
launch.removeAllListeners();
});
// RVM failed to find an available runtime version
launch.on('app-version-error', (error) => {
console.log("Failed to resolve " + error.srcManifest + " from the fallbackManifests");
launch.removeAllListeners();
});
}
});
Monitors a running process. A pid for the process must be included in options.
A uuid may be optionally provided. If not provided, OpenFin will create a uuid for the new process.
If an unused uuid is provided in options, it will be used. If no uuid is provided, OpefinFin will assign a uuid.
fin.System.monitorExternalProcess({
pid: 10208,
uuid: 'my-external-process', // optional
listener: function (result) {
console.log('the exit code', result.exitCode);
}
}).then(processIdentity => console.log(processIdentity)).catch(err => console.log(err));
Adds a listener to the end of the listeners array for the specified event.

Optionaloptions: SubscriptionOptionsEvent payloads are documented in the OpenFin.Events namespace.
Opens the passed URL in the default web browser.
The URL to open
It only supports http(s) and fin(s) protocols by default. In order to use other custom protocols, they have to be enabled via API security settings. File protocol and file path are not supported.
fin.System.openUrlWithBrowser('https://cdn.openfin.co/docs/javascript/stable/tutorial-System.openUrlWithBrowser.html')
.then(() => console.log('Opened URL'))
.catch(err => console.log(err));
Example of permission definition to enable non-default protocols:
Note: permission definition should be specified in an app manifest file if there is no DOS settings. Otherwise it has to be specified in both DOS and app manifest files.
"permissions": {
"System": {
"openUrlWithBrowser": {
"enabled": true,
"protocols": [ "msteams", "slack"]
}
}
}

Query permission of a secured api in current context.
The full name of a secured API.
If a function has a structured permission value, the value of granted will reflect the enabled key
of the call's permissions literal. In this case, permission may still be denied to a call pending arguments or other
runtime state. This is indicated with state: unavailable.
fin.System.queryPermissionForCurrentContext('System.launchExternalProcess').then(result => console.log(result)).catch(err => console.log(err));
//This response has the following shape:
