![]() The most common way of supplying the token is via a HTTP header, which looks like this. QuickBooks - Parse the JSON of a Customer Balance Detail Report. ![]() So getting data from an endpoint is pretty easy but most rest APIs require an authentication token in order to verify your request. JSON Parsing with Sample Data for a Merchant/Payment Transaction. 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. The most common case I tend to use this method for is querying or posting to a json rest API's. We will use this example to get some JSON to work with. This command can query any web service or site over HTTP and return information (not just JSON). POWERSHELL JSON QUERY WINDOWSThe 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. Use the Invoke-Request Command in PowerShell To query an API with Windows PowerShell and get some JSON in return is to use the Invoke-WebRequest command. 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. The JSON format works off of collections of key:value pairs that can be organized into objects and arrays. Better yet, it’s supported by both PowerShell and SQL Server. This eliminates the need for some of the syntax. PowerShell makes working with rest API's easy. JSON (JavaScript Object Notation) is a human-readable file format intended for transmitting data (usually between a server and app interface). Last but not least, hashtables are also great for making your JSON input, along with the ConvertTo-Json cmdlet. ![]()
