PreLab Configuration Steps:

Throughout this and other classes in the series we will make use of the Postman REST API Client. You can find more information about Postman at https://getpostman.com

Task 1 - Import the Postman Collection & Environment

In this task you will Import a Postman Collection & Environment for this lab. Perform the following steps to complete this task:

  1. Open the Postman tool by clicking the postman-icon icon of the desktop of your Jumphost. The initial window may take a few moments to appear.


    The Postman client receives very frequent updates. If you are prompted to update the client please click the Remind me later button to skip updating the version installed in your lab environment

  2. By default, the Postman client requires verification of SSL/TLS Certificates to a public Root Certificate Authority. However, by default, BIG-IP and many other devices use a self-signed certificate for SSL/TLS connections. To allow connections with self-signed certificates we need to modify the default settings of Postman.

    • Open the Postman Settings windows by clicking File ‣ Settings:


    • Verify your client is configured to allow self-signed certificates by setting SSL certificate verification to OFF


    • Click the X in the top right of the Settings window

  3. A Postman Collection lets you group individual REST requests together. This Postman collection can then be shared and imported. To import a Postman Collection, click the Import button in the top left of the Postman window


  4. Click the Import from Link tab. Paste the following URL into the text box and click Import



  5. You should now see a collection named F5 SecDevOps in your Postman Collections sidebar. Postman automatically resizes its GUI depending on its window size. It might be necessary to use the short Ctrl + \ (on Windows) or click the show sidebar icon at the bottom left corner of postman if you do not see the sidebar.


  6. To assist in multi-step procedures we make heavy use of the Environments capability in Postman. This capability allows us to set various global variables that are then substituted into a request before it’s sent. Import the Environment file by clicking Import ‣ Import from Link and pasting the following URL and clicking Import:

  7. Set your environment to F5 SecDevOps by using the menu at the top right of your Postman window:
