How to use Postman and PowerShell to Query API Data

Postman and PowerShell

In this video, I demonstrate how to use Postman, a free API development and testing tool, to format URL’s and make requests against web endpoints and use those URL’s to get data in PowerShell.  I also give a quick walk through of viewing the data in PowerShell.

One thought on “How to use Postman and PowerShell to Query API Data

  1. Hi Travis,

    I am trying to work with invoke-restmethod for the first time. I have a URL from our HR provider. I know this URL works as I get an output in Postman using the key in the header. However when I use invoke-restmethod in PowerShell I get no out put.

    PS C:\WINDOWS\system32> $params

    Name Value
    —- —–
    ContentType application/json
    Method GET
    Headers {X-SFAPI-AppName, X-SFAPI-RSAKey, X-SFAPI-Account}
    Uri https://sfcola1.dataon.com/sfapi/index.cfm?endpoint=/philippinedemo_FULL_SDP_Emp_Info

    PS C:\WINDOWS\system32> (Invoke-RestMethod @params).length
    0

    Can you please help me out what could be wrong or what is causing the no output in the Invoke-RestMethod command?

    Thanks
    Ivan
