The most common way of supplying the token is via a HTTP header, which looks like this. So getting data from an endpoint is pretty easy but most rest APIs require an authentication token in order to verify your request. For a json endpoint, I'll automatically get a PowerShell object (hashtable) that represents the json response. The value returned will be automatically parsed depending on the content type of the response. However, if this parameter is omitted and the request method is POST, Invoke-RestMethod sets the content type to "application/x-www-form-urlencoded". For example, this GET request won't have a content type. This will default to a GET request, and any unsupplied optional parameters are omitted from the request. The simplest call you can make is to just provide the URL. I usually end up just using Invoke-RestMethod so I'll focus on it. First, we will check the sample input JSON file created above and how we can. The ConvertTo-JSON cmdlet converts any possible output to the JSON format and the ConvertFrom-JSON cmdlet converts the JSON input to the custom Object or the hashtable format. The most common case I tend to use this method for is querying or posting to a json rest API's. PowerShell uses the two cmdlets ConvertTo-JSON and ConvertFrom-JSON to work with JSON files. The difference between the two is quite small, Invoke-RestMethod simply being a slightly more convenient wrapper around Invoke-WebRequest as it only returns the content, omitting the headers. NET model you had to work with previously turning a request into a concise one liner similar to curl (Which is also an alias for Invoke-WebRequest in PowerShell). These cmdlets are a huge improvement coming from the. In PowerShell version 3, the cmdlets Invoke-RestMethod and Invoke-WebRequest where introduced. As the world continually becomes eaten by software more and more services are being replaced by software. When working with PowerShell, Microsoft has provided some helpful tools to work with JSON called the ConvertTo-Json and ConvertFrom-Json commands.
