• Hi guys,

    I’ve noticed in recent RC’s that an API is being implemented and wondered if there is any basic info on how to use it ?
    I’ve searched google and the forums but can’t seem to find any info.

  • @wayne-workman
    Thx. I figured out where was the issue. Maybe this info will help somebody.
    I use curl under Windows, but command line doesn’t support single quotes '.
    I used " and had to escape inner ones
    –data “{\“hostID\”:13}”

  • @andrewg78 Probably, I’ll have to look into it. Multicast tasks are handled differently than unicast tasks - they are treated as an individual job. If you wanted to get the status of the entire job, you could probably just follow along with the examples in this link: https://forums.fogproject.org/topic/9779/can-i-use-some-kind-of-script-to-create-image-and-ghost-my-lab-machines Though you would need to use the multicast task type, or know the task ID already.

  • Hi, Could you please share an example of query to obtain list of active tasks per given GROUP ID?
    I just want to check if all multicast jobs are done in a specific group.

  • basicconfig.ps1

    <# Config for our scripts.
            Just used to store our common variables that we don't want to
            recode for every script.
            No related usage, just sets variables.
    $fogApiToken = "TokenFromGUIForAPIAccess";
    $fogUserToken = "TokenFromGUIForUserToken";
    $endpointURL = "http://fogserver/fog/";

  • @george1421 There’ s a simpler method

    Here’s some scripts that I run.

    This is specific to my needs on a different project, but could be converted as needed.


    <# Build headers script help
            This powershell script just creates a single point for building headers
            rather than constantly rewriting the same script over and over.
            This just sources the function so there is no real usage here.
    function Build-Headers {
        $header = @{
            "fog-api-token" = $fogApiToken;
            "fog-user-token" = $fogUserToken;
            #"Accept" = $accept;
            "Content-Type" = $contentType
        Write-Verbose("---------- Headers ----------");
        Write-Verbose("Authorization: " + $authorizationString);
        Write-Verbose("fog-api-token: " + $fogApiToken);
        Write-Verbose("fog-user-token: " + $fogUserToken);
        Write-Verbose("Accept: " + $acceptType);
        Write-Verbose("Content-Type: " + $contentType);
        Return $header

    Use case script – To create a task for a host with say ID # 10.


    <# Creates Task for id passed in to script.
            Helps create task from command line.
        .PARAMETER id (required)
            This is the ID Of the Host to task.
        .PARAMETER configFile (optional)
            This is not a required file, this allows you to use a different
            basicconfig.ps1 file if need be.
    # Set errors to silent if we are not in verbose mode.
    If (!$PSCmdlet.Myinvocation.BoundParameters["Verbose"].IsPresent) {
        $ErrorActionPreference = "SilentlyContinue"
    # Setup up defailt if configFile is not already set.
    If (!$configFile) {
        $configFile = '.\basicconfig.ps1'
    # Load our config file.
    . $configFile
    # Set our base call (item) for the api.
    $baseURL = $endpointURL + "/host/" + $id + "/task"
    # Source build headers function.
    . ".\buildheaders.ps1"
    # We know we're using json so set accept/content type as such.
    $contentType = "application/json"
    # Get our headers Building off the config file information.
    $headers = Build-Headers $fogApiToken $fogUserToken $contentType $contentType
    # Display what url we are calling so somebody could use it later if in verbose.
    Write-Verbose ""
    Write-Verbose "---------- Caller URL ----------"
    Write-Verbose ("URL: " + $baseURL)
    Write-Verbose "--------------------------------"
    Write-Verbose ""
    $dataSet = @{
        "taskTypeID" = 1
        "shutdown" = true
    $dataToSend = ($dataSet | ConvertTo-JSON)
    # Display the data we're sending
    Write-Verbose ""
    Write-Verbose "---------- Sending Body ----------"
    Write-Verbose $dataToSend
    Write-Verbose "----------------------------------"
    Write-Verbose ""
    # Perform the request
    $ret = Invoke-RestMethod -Method Post -Uri $baseURL -Headers $headers -ContentType $contentType -Body $dataToSend
    # Write our return information if there is anything to see.
    Write-Verbose ""
    Write-Verbose "---------- Returned Data ----------"
    Write-Verbose $ret
    Write-Verbose "-----------------------------------"
    Write-Verbose ""
    # All Done

    You would have all three files in the same place and call from powershell:
    .\taskhost.ps1 -id 10

    Hopefully this helps. Of course it could be more generalized, but I’m just giving a basic overview.

    @UWPVIOLATOR Warning: I’m not a programmer (or even know how to program in PS) and sometimes I even question if I know what I doing here…

    But I think I was able to translate one of Wayne’s posts with a curl call into powershell.

    curl --silent -k -H 'Content-Type: application/json' -H 'fog-user-token: ZjBkMmE3YmI5NmUzZDcxYTliYzNkZTc4MmJhNTFiYTQ3Mzc2MTg5MzYxMThmNjA5NDYyMjllMTA5YzE0NWUxMjFiNzkyMTc5OTMwZjFhZGM5NWIxMTc3YWZmNTU2MmMwYjFhNjg0NjVmMTkyMGZkNDQxYmY0MzI1NWNkMzQyM2M=' -H 'fog-api-token: MzI2NDY1NjY2NjM0MzUzMDMzMzA2MzM1MzEzNzYyMzg2NTYyNjQ2MjMxMzczMTM0NjY2NDM0NjUzOTM2NjIzNDM4MzQ2NDM3MzY2MzM2MzMzNjYyMzUzODY0MzUzNDYyMzgzMDY2NjQzNTMxMzI2MzM5NjYzNjYzMzMzMzM0MzA=' -d '{"taskTypeID":1,"shutdown": true}'

    would translate into something like this:

    $headers = @{}
    $headers.Add("fog-user-token", "ZjBkMmE3YmI5NmUzZDcxYTliYzNkZTc4MmJhNTFiYTQ3Mzc2MTg5MzYxMThmNjA5NDYyMjllMTA5YzE0NWUxMjFiNzkyMTc5OTMwZjFhZGM5NWIxMTc3YWZmNTU2MmMwYjFhNjg0NjVmMTkyMGZkNDQxYmY0MzI1NWNkMzQyM2M=")
    $headers.Add("fog-api-token", "MzI2NDY1NjY2NjM0MzUzMDMzMzA2MzM1MzEzNzYyMzg2NTYyNjQ2MjMxMzczMTM0NjY2NDM0NjUzOTM2NjIzNDM4MzQ2NDM3MzY2MzM2MzMzNjYyMzUzODY0MzUzNDYyMzgzMDY2NjQzNTMxMzI2MzM5NjYzNjYzMzMzMzM0MzA=")
    $mydata = @{}
    $mydata.Add("taskTypeID", "1")
    $mydata.Add("shutdown", "true")
    $json = $mydata | ConvertTo-Json
    $Uri = ''
    Invoke-WebRequest -Method Post -Uri $Uri -Header $header -Body $json -ContentType 'application/json'

    @UWPVIOLATOR Not the answer you are looking for, but a bit more details that Wayne uses for FOG scripting. https://forums.fogproject.org/topic/9779/can-i-use-some-kind-of-script-to-create-image-and-ghost-my-lab-machines/15

  • @theWizard

    What did your Powershell command look like? I would like to see that example. I am most familiar with it and the one main thing I need to work on is a for each from a csv file with all of our old junked computers and laptops returned from lease. We no longer need them in fog.

  • @Tom-Elliott
    I’m using powershell with Invoke-WebRequest which is alias for curl

  • @theWizard I don’t follow.

    What are you using as a test, exactly?

  • @Tom-Elliott said in API:

    curl -H ‘fog-api-token: abcde’ -H ‘fog-user-token: fghij’ -X GET http://fogserver/fog/task/current

    Thankyou perhaps i will have to wait as anything i try results in
    The requested URL /fog/task/current was not found on this server.

  • This is just a quick means to represent how you could filter the tasks if you needed to as well.

    Our “List all tasks” works without a body sent, but CAN be filtered to get specific information for active tasks. The example just shows how you might want to get active tasks for host ids of 5 and 6. I’m not trying to show actual payload right now. Just trying to show example use cases.

    So let’s do this command line style:
    Let’s just say your api token is abcde
    Let’s just say your user token is fghij
    List all current/active tasks is a GET request.
    URL for now is just fogserver

    curl -H 'fog-api-token: abcde' -H 'fog-user-token: fghij' -X GET http://fogserver/fog/task/current -o listalltasks.json -d '{"hostID":[5,6]}'
  • Moderator

    #wiki worthy

  • @theWizard

    List all active tasks:

    header('fog-api-token: <FOG Configuration Page->FOG Settings->API Settings->FOG_API_TOKEN>');
    header('fog-user-token: <User management page->relevant user->API Settings->User API Token>');

    So let’s do this command line style:
    Let’s just say your api token is abcde
    Let’s just say your user token is fghij
    List all current/active tasks is a GET request.
    URL for now is just fogserver

    curl -H 'fog-api-token: abcde' -H 'fog-user-token: fghij' -X GET http://fogserver/fog/task/current -o listalltasks.json

    This will list all current/active tasks to a file in the current working directory named listalltasks.json

    For creating a snapin task, this depends how you plan to do it. To be honest, while the option is available, it’s not something I’ve worked overly hard to get working “natively”. It was originally only designed to allow host and group, though I saw the appeal and added capabilities.

    So let’s just say you have a snapin associated to a host.

    The snapin ID is: 6
    The host ID is: 1

    This would be a POST request as per the earlier information.

    The URL you would call would be:


    The post requires some information, and luckily I kind of documented the “maximum” and “minimum” information for creating a tasking in this way.

    The “data to send” would be, at minimum:

        "taskTypeID": <IDOFTASKTYPETOUSE>

    For a “snapin” task, this is ID’s 12 or 13. important to remember which is a single snapin, vs. all snapin though.

    The “full” information you could send for tasking in a manner as above is:

        "taskTypeID": <IDOFTASKTYPE>,
        "taskName": "NameToGiveTasking",
        "shutdown": <bool>true/false,
        "debug": <bool>true/false,
        "deploySnapins": <bool>/<IDOFSNAPIN or -1 for all>,
        "passreset": "what to change password if passreset task",
        "sessionjoin": "<SessionNameToJoin>",
        "wol": <bool>

    In your case, with a specific known host and snapin to send you could do:

    curl -H 'fog-api-token: abcde' -H 'fog-user-token: fghij' -H 'Content-Type: application/json' -X POST -d '{"taskTypeID":13,"deploySnapins":6}' http://fogserver/fog/host/1/task

    This should create the tasking for you as you described. (Task Type ID 13 = Single Snapin Task, deploy Snapins is true/false/-1 = all/<IDOFSNAPIN>

    @theWizard The API is RESTful based. You might want to do a quick read up on RESTful interfaces. https://www.tutorialspoint.com/restful/

    Once the API is finished we will create guidance on using it. Actually what Tom posted below is the first time this information was made publicly available.

    Please give us some time to get the documentation in line with the advances the developers are making in the code.

  • @Tom-Elliott said in API:


    Hi Tom
    Thanks you for the detailed response much appreciated, i feel rather stupid asking but i don’t suppose you have a couple of examples to follow do you ?
    Say for instance if i wanted to list all active tasks or even add a snapin task.

  • Right now there isn’t much in terms of documentation. We are working toward getting there.

    Understand the API system is very new, but as much as I could “simply” implemented.

    What I mean with this:

    1. Data body or return is done with JSON.
    2. All objects in the core have some ability to managed with the API system with the only exception, so far, being Users.

    There are a few important bits in regards to interacting and using the API System.

    1. API Can be globally enabled/disabled.
    2. API Can be user enabled/disabled. – (You can define which users you want to have access to the api system.)


    1. API Global token is a header required with the name fog-api-token
    2. API User token is a header that can be used (Highly recommended) being passed as a header in the form fog-user-token
    3. You can not manually create the tokens via the presented text fields. This is what the purpose of the “Reset Token” Buttons are. There’s a Reset Token for the global API as well as one for each user.
    4. Tokens are cryptographically generated so no two tokens will be known regardless of how many FOG Server’s you decide to install. There is no “default” token essentially. This holds true for both User and Main API Tokens.

    You can use HTTP Basic Authorization (with curl -u <user>:<password> or header with name Authorization: Basic <base64encoded username:password>
    Although I have allowed the ability for this type of authentication, and it will work, I would still recommend using user token system as it cannot be received and decoded to a valid username/password pair to manage your fog server.

    Routes and Methods:


    1. /fog/system/info Returns 200 if accessible
    2. /fog/system/status Alias for #1
    3. /fog/<objectactivetasktype>/current Returns listing of “active” items. Active referring task types, (Snapin Task, Snapin Job, Task, Scheduled, Multicast)
    4. /fog/<objectactivetasktype>/active Alias for #3
    5. /fog/<object>/search/<whatareyousearchingfor> Idea is similar to the Search Page from GUI.
    6. /fog/<object> Same idea as “List all”
    7. /fog/<object>/<IDOFOBJECT> Same as if clicking edit on an item (only just to get its information).

    PUT (Requires a json body)

    1. /fog/<object>/<IDOFOBJECT>/edit Update the object.
    2. /fog/<object>/<IDOFOBJECT>/update Alias for #1

    POST (Requires a json body)

    1. /fog/<objecttasktype>/<IDOFOBJECT>/task Task object.
    2. /fog/<object>/create Create new object.
    3. /fog/<object>/new Alias of #2.


    1. /fog/<objectactivetasktype>/cancel Cancel specific items (requires json body)
    2. /fog/<objecttasktype>/<IDOFOBJECT>/cancel Cancel specific task for object.
    3. /fog/<object>/<IDOFOBJECT>/delete Delete/Remove object.
    4. /fog/<object>/<IDOFOBJECT>/remove Alias of #3


    1. /fog/system/info Returns 200 if accessible
    2. /fog/system/status Alias for #1

    I realize this is not a full on “here’s everything” but it’s something that should be able to help get you along the path.

    Plugin’s Compatibility.

    I have worked relatively hard to implement capability for plugins to also tie in with this. This means hooks can be used to implement API level functionality with plugins or custom elements you’d like to use.

    Hook Event Names what core element it ties in with:

    1. API_VALID_CLASSES, variable to adjust is labeled ‘validClasses’. Ties in with <object> items.
    2. API_TASKING_CLASSES, variable to adjust is labeled ‘validTaskingClasses’. Ties in with <objecttasktype> items.
    3. API_ACTIVE_TASK_CLASSES, variable to adjust is labeled ‘validActiveTasks’. Ties in with <objectactivetasktype> items.
    4. API_MASSDATA_MAPPING, variables to adjust are labeled ‘data’, ‘classname’, and ‘classman’. Operates on the “list” and “search” type routes.
    5. API_INDIVDATA_MAPPING, variables to adjust are labeled ‘data’, ‘classname’, and ‘class’. Operates on individual objects such as /fog/<object>/<IDOFOBJECT>
    6. API_GETTER, variables to adjust are labeled ‘data’, ‘classname’, and ‘class’. Operations for all items and is used to present the return of data in a common way regardless of what object is being called.
    • In regards to #6 of the Hook Event elements, think of it as this:
      If I request information about a task, one of the elements of a task is the “host” object. The data presented in the “Task” return for a specific host will look the same in the task return as it would if you looked the host up individually. For example, if the task is using a hostID of 7, the ‘host’ item in this element would look identical to the return data if you were go to route /fog/host/7
