Integrating WordPress blog into SharePoint 2013

1796 Views

In this blog article, I will discuss about how we can easily integrate a WordPress blog with your SharePoint site with the help of SharePoint 2013 designer Work Flow.

Introduction

Using SharePoint 2013 REST API and building SPD based simple Workflow, we will fetch most recent 2 or more post from the blog site and add those in a SharePoint list.

If you are more interested about the advantages and disadvantages of the REST API, and for a comparison with other API’s, please refer the MSDN site here.

REST API Reference

Firstly, we will try to get the REST API provided by WordPress. Let’s go to WordPress developer's resources site.

http://developer.wordpress.com/docs/api/

Here, you can get the list of REST API, from which you can choose as per your requirement.

In order to retrieve most recent 2 blogs we will be specifying the number=2 in the parameter such as below:

https://public-api.wordpress.com/rest/v1/sites/yourwordpressblog.com/posts/?number=2

Building SP2013 SPD Workflow

Open the SharePoint Designer and click on site work flow.

As you can see in the image, we will build a site workflow named "Get WordPress Recent Blogs", which will read the information from WordPress Blog, create list items in a SharePoint list for further use.

Once the site workflow is created, you simply add stages, loops and name them properly, and then link them actions.

Name Stage 1 “Get Myblog Recent Items” and then add five actions and one Loop block, as shown in Figure 1.

Figure 1. Workflow Stage 1

  • Action 1 is not really required, but it will add one item to the history list, which can be used for debugging.
  • Action 2 is added to Call HTTP Web Service action. The HTTP URL is set to https://public-api.wordpress.com/rest/v1/sites/yourwordpressblog.com/posts/?number=2 and the HTTP method is set to “GET”.
  • Action 3 is again logging to history, the response should be “OK”. This means the WF is calling API perfectly.
  • Now we are creating a variable “itemcount “as Integer and setting the value to 2, since we require only 2 blogs.
  • Last action is to create another variable “Index” and set the value to 0.

In the "Call HTTP Web Service" action statement we do not set RequestContent or RequestHeaders parameter because we do not need to. We are only interested in the output of that web service. By simply setting the response parameter to a variable ResponseContent, the output of this web service call will get stored in the variable ResponseContent, which is a dictionary type variable.

The output of the web service looks like the following:

{"found":5,"posts":[{"ID":124,"author":{"ID":7899331,"email":false,"name" ……………..

To handle each blog item we could use the “responsecontent” variable so that we can put our action statement like “Get ([%Variable: Index%])/Title from Variable: responsecontent” to get Post’s property.

From the web service output we can see the ID, title. These are within “posts{“. Just to make things simple and to show a clear structure of post inside web service output, the full path to access post’s properties, the statement like “Get posts[%Variable: Index%])/ID from Variable: ResponseContent“ will retrieve ID property of an item.

These are the workflow variable details:

Figure 2 shows all the different action items.

  • Firstly, pick the ID
  • Next, delete the same ID if the item exits in the SP list
  • Next four action is updating the variables with posts’ value
  • Last item in the loop is to add an item in the SharePoint List

Now increase the counter by 1 and the same actions are for the 2nd Item.

This is it! You are now you are ready to publish and start this workflow.

If you want to run the workflow daily, then add another action item after the loop end such as below:

Now your SharePoint List will have the blog content . That’s it :)

Conclusion

Lastly, adding a delay for 24 hours every day will enable the list to update with 2 recent blogs. This is a very simple yet very powerful example of REST API and SPD workflow.
