Call HTTP Web Service In SharePoint 2013 And Office 365 Using Nintex Workflows

Welcome to an article on how to Call HTTP Web Service in SharePoint 2013 and Office 365 using Nintex Workflows. This article will display the action “Call HTTP Web Service” so that all my developer friends don’t have to spend much time and effort while using this function in their projects.

Using this action you can call HTTP request to a URL and perform requests as REST which we will see on the configuration part of the workflow. Let’s see the implementation of this functionality.

• Create a list, Dev Testing.
  
  
• Click on the LIST tab on the Top ribbon and click on Nintex Workflows.
  
  
  
  
• You will see the following screen to create a new workflow.
  
  
• Click “Create new workflow”.
  
  
  
  
• You will come to the design phase of the Nintex workflows.
  
  
• Add the action, “Call HTTP Web Service” either by right click on the workflow or by dragging and dropping from the left toolbox.
  
  
  
  
• Now let’s configure it.
  
  
• When you double click on the action the following screen opens up.
  
  
  
  
  

Form Parameters

• Address: Here you can assign the url from where you want to call web request from.
  
  
• Request Type: The following are the type of requests:
  
  - HTTP Get
  - HTTP Put
  - HTTP Post
  - HTTP Delete
  
  
  
  
• Request Headers: Here you can specify a variable to store the value of the headers.
  
  
• Request Content: Here you can specify a variable to store the content.
  
  
• Response Content: Here you can specify a variable to store the response of the content.
  
  
• Response Headers: Here you specify a variable to store the response of the header.
  
  
• Response Status Code: Here you can specify a variable to store the response of the status code.
  
  
• Now we have configured our workflow, let’s go and publish it to use it.
  
  
• Click on Publish on the left corner of the ribbon of Nintex Designer.
  
  
  
  
• You will see the following screen:
  
  
  
  
• Give your workflow a name.
  
  
• Description.
  
  
• Choose your task list where it should store the tasks, It will be Workflow Tasks by default.
  
  
• Choose your history list where it should store the history logs, It will be Workflow History by default.
  
  
• Start Options:-
  
  You can either start your workflow manually.
  
  Or you can start your workflow automatically when an item is created. In our case we will make it as Start when items are created.
  
  Or you can start your workflow automatically when an item is modified.
  
  
• Click on Publish
  
  
• Your workflow will get published.

The values which you received and store in the variables can be updated to a list item so when you run this workflow, it will create a new item with all the values of the variables updated on the list as an item.

So in this article we saw how to call HTTP Web Service in SharePoint 2013 and Office 365 using Nintex Workflows,. We will see more new articles on the actions of Nintex Workflows in the other parts of the article. Till then, keep learning!
