    Making an API Request

    Article summary

    Skillable has developed a number of REST APIs to assist you to interact with and maintain your accounts on the Skillable Studio and TMS platforms, launch and monitor labs, retrieve data, integrate external systems, and more. This article will highlight a couple methods that API administrators and developers can use to make an API request using the Skillable Studio and TMS REST APIs.

    This article will highlight some of the methods you can use to make an API request as well as highlight the API request format. Also covered in this article is some of the tools that you can use when developing and testing your API requests.

    Required Permissions

    Skillable APIs offer one form of authentication: an API Key. All methods require an API Key, which must be obtained from a Skillable team member working with your organization. Our systems use this key to validate your development account.

    Pass your API Key as an HTTP request header with the header name "api_key". No other permissions or authentication will be required to complete an API Request.

    In Skillable Studio APIs, the API Key is configured as part of the API Consumer while in Skillable TMS, the API Key is associated with Organization accounts.

    When developing labs on the Skillable Studio platform you may have access to both a development and a production environment. These environments will likely require separate API Consumers providing different API keys.

    If you do not have an API Key for your environment(s), please reach out your Skillable representative or contact the customer support team for assistance.

    Best Practices

    API Workflow

    As a best practice the API key should never be exposed to client side code. Below is a sample workflow for using and integrating API calls. The sample assumes that the client side has a button or page that the student selects to launch a lab via API.

    1. Student selects a button that initiates the API call.

    2. An ajax call is made to the customer-owned service or learning management system.

    3. The customer-owned service makes a Launch API call and receives the lab URL from Skillable Studio.

    4. The ajax call returns to the browser and includes the lab URL.

    5. Client-side code redirects to the URL or spawns a new window and directs the new window at the lab URL.

    Spawning a new window is preferred for the following reasons:
    • Spawning a new window allows for the browser window to be resized to the ideal size for the student's machine.
    • Resizing can't be done in a redirect, as browser's do not allow resizing of user-opened windows.
    • The student is able to maintain the page they launched the lab from.
    • It is best practice to launch the lab in its own window, so the student can navigate to the page the lab was launched from if needed.

    Do not use Strict Mapping

    We advise against using strict mapping of API objects. We will add new API objects, but we will not remove any API objects that are already in place. If API objects are strictly mapped, your API integration may not work properly when new API objects are added.

    Window Manipulation

    If you launch a lab in a new window using JavaScript, Skillable Studio will resize the lab window after it is launched.

    To launch a lab in a new window, use the following JavaScript:, "lab", "width=800,height=600,status=0,resizable=1,toolbar=0,menubar=0,location=0,scrollbars=0");

    This tells the browser to open a new window with dimensions of 800x600. After a new window is opened, Skillable Studio will resize the window appropriately for the lab type that is being launched (Virtualization or Cloud Slice). Since the initial window dimensions were set by a script, future scripts are permitted to change those dimensions (resize the window).

    Windows spawned in any other context are only resizable by the user. If you open the window using an HTML link, or simply redirect the current window to the lab URL, Skillable Studio will be prevented from resizing the window.

    • Cloud Slice labs consist of two windows; the resource portal and lab console.
    • Virtualization based labs consist of one window; the virtual machine and the lab console.
      Lab console: on the right side of the screen, housing the instructions and any lab resources.
      Resource portal: on the left side of the screen, housing the cloud platform or the virtual machine(s) that the lab utilizes.

    How to Make an API Request

    API Requests can be submitted to launch a lab, obtain profile information, update accounts and more. The general format of the request will not change regardless of whether you making a request on the Studio or TMS platforms.

    • API Requests are not case sensitive.

    • Requests can use either the HTTP verb GET or POST.

      • GET: used to request data from a specified resource.
      • POST: used to send data to a server to create/update a resource.

      NOTE: The Skillable Studio and TMS APIs have been designed to use the GET verb for most API requests. Refer to the specific API endpoint documentation found on the Connect website for more details.

    API Request Format

    API requests use Methods and Parameters in the URL.

    A typical API request would look like:[method]?[parameters]

    An example request to launch a lab will look like:

    launch is the method.

    labid, userid, firstname, lastname and email are the parameters.

    labidThis is the lab ID of the lab that is to be launched. The ID can be found in the URL while viewing the lab profile in Skillable Studio.
    useridThe user ID you use to identify the user in your external system.
    firstnameThe first name of the user that the lab launch will be associated with.
    lastnameThe last name of the user that the lab launch will be associated with.
    emailThe email address on the user profile of the user that the lab launch will be associated with.

    API Testing Tools

    If you want to test your API requests before implementing them, you can do so using an API testing tool. There are many tools available for testing an API request. One of the most common tool used is Postman, and is available on Windows, macOS and Linux (x32/x64).

    Try It

    The API Documentation website has a try-it function in the top-right panel of each API endpoint that provides testing capabilities as well as sample code in various scripting languages and a JSON sample of the resulting output.

    You may download a OpenAPI collection of calls directly from the Connect website. The OpenAPI collection can be imported directly into a Postman Collection for easy access. Be sure to edit the authorization header to include the appropriate API Key.

    In this article, we will walk through the steps to use the Studio /Launch APi request, to launch a specified lab for a specified user using the Postman API Testing tool.

    Use the API documentation for the /Launch command as reference.

    To launch a lab via an API request in Postman:

    1. Download Postman for your operating system.

    2. Once the appropriate package for your operating system has been downloaded select it to launch the installer and install Postman.

      • Follow the prompts to complete the Postman installation.
    3. When the installation has completed, open Postman.

    4. To create a new request, select the + (plus) icon in postman .

      Postman Plus

    5. A new Untitled Request tab will open providing all the fields and attributes necessary to create an API request. Ensure that the HTTP verb field matches the verb indicated in the Connect website documentation. In the case of the /Launch command an HTTP verb of GET should be selected.

      Postman GET

    6. Copy the following /Launch API example and paste it into the URL field in Postman.

      Postman URL

    You'll see that Postman parses the URL and displays query parameters in the appropriate field in the Value column.
    Postman Query Params

    1. Replace the text in the value column, with data that corresponds to the key column.

      labidReplace 100 with the lab ID of the lab that is to be launched.
      useridSet the user id of the user to be used to launch the lab.
      firstnameEnter the first name of the user launching the lab.
      lastnameEnter the last name of the user launching the lab.
      emailAdd the email address of the user launching the lab.

      Postman Replaced Values

    2. In order to properly authenticate the API request the appropriate API Key will be required. Since the /Launch API endpoint command is a Studio function you will need the correct API Key from the API Consumer linked to the Lab Series that the Lab Profile was published to.

    API access requires an API key

    If you do not have access to the API Consumer, or can not retrieve the API Key contact the customer support team for assistance.
    Studio API Key

    1. In Skillable Studio select the Copy link for the API Key you will use to authenticate the /Launch API request.

    2. In Postman, select the Authorization tab, expand the Type list and select API Key.

      Postman Authorization

    3. Paste the API Key from the API Consumer in Skillable Studio into the Value field in Postman ensuring that the Add to field has the value of Header.

      Postman API Key Value

    Use API Header Key

    Alternatively, you can select the Headers tab, add the key name api_key to the Key column and paste the API Key from the API Consumer in Skillable Studio to the Value column.

    Next Steps

    The same API Request can be made in the Connect website using the Try it function. We would encourage you to explore this functionality using that tool as well.


    The Try it function only works for production Skillable Studio and TMS environments.

    Reference Materials

    The Postman application is a powerful tool for developing API Requests. Refer to their official documentation for more information.

    The Skillable Studio and TMS Restful APIs are fully documented on the Connect website. Refer to this site for information about all the publicly available API endpoints.
