Hi,<br />
<br />
I am a complete novice with REST APIs but have managed to connect to one using SOAPUI. <br />
<br />
My next step is that I need to perform a similar connection using a powershell script.<br />
<br />
So I need to connect using a Post method.<br />
<br />
1. Obtain the authorization value<br />
2. Use the value obtained as part of the authorization request as a &quot;Request parameter&quot; to make a Post call by using a pre-defined variable.<br />
3. Use a further parameter to specify the data format i.e. json

Hi,

I am a complete novice with REST APIs but have managed to connect to one using SOAPUI. 

My next step is that I need to perform a similar connection using a powershell script.

So I need to connect using a Post method.

1. Obtain the authorization value
2. Use the value obtained as part of the authorization request as a "Request parameter" to make a Post call by using a pre-defined variable.
3. Use a further parameter to specify the data format i.e. json

Make a REST call using Powershell

Windows PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language built on the .NET Framework. PowerShell provides full access to the Component Object Model (COM) and Windows Management Instrumentation (WMI), enabling administrators to perform administrative tasks on both local and remote Windows systems as well as WS-Management and Common Information Model (CIM) enabling management of remote Linux systems and network devices.

Powershell

Representational state transfer (REST) is an architectural style that gives a coordinated set of constraints to the design of components in a distributed hypermedia system used to design networked applications. RESTful systems typically communicate over Hypertext Transfer Protocol (HTTP) with the same HTTP verbs (GET, POST, PUT, DELETE, etc.) that web browsers use to retrieve web pages and to send data to remote servers. REST interfaces with external systems using resources identified by Uniform Resource Identifier (URI) that can be operated upon using standard verbs.

REST

JavaScript Object Notation, or JSON, is human-readable text used when transmitting data objects consisting of attribute:value pairs between a server and a web application as an alternative to XML. JSON, while it is originally derived from JavaScript, is a language-independent data format. Code for parsing and generating JSON data is available in many programming languages.
