So today I started creating a new custom approval using Microsoft Flow. I had been working for about 15 minutes or so and thought to myself that it may be a really good idea for me to save my work because we all know that if I didn’t do it soon something would cause me to lose everything (because initial save hadn’t been accomplished yet. When I clicked on the save button I received an error I hadn’t received before. “Tag value to large. Following tag value…exceeded the maximum length. Maximum allowed length for tag value – ‘256’ characters.
When the business wants to control the data that is displayed to users a great way to do this is with content approval. It’s easy to implement and use. Simply enable the option in version control and anyone with Full Control, Design or Approve role is able to approve the items.
There is a great write-up by Chakkaradeep Chandran on how to automate the approval process of these items. However, what Microsft Flow is missing is the ability to see what status the approval process is at. There are many requests for this information in the Flow forums with no solutions beyond statements that Flow is lacking in this ability. I was able to come up with a working solution to achieve this. So read on to learn how to determine the approval status of a SharePoint list or library item.
Now that I have completed my series on building a modern solution with SharePoint, PowerApps and Flow I want to start building on that solution. The next enhancement I wanted to do was allow the capture comments from the approver in Microsoft Flow. So whether the approver approved or rejected the request I want to be able to capture the comments if they provided any. Because this is building on my previous solution you can see how that was built by clicking here.
Something that is used a lot in Microsoft Flow is the HTTP request. Whether you are calling a site’s REST endpoint or an Azure function, or in the case of today a SharePoint REST endpoint you need to be able to do something with the data returned. The steps to do that are very simple and only require a free tool called Fiddler. You can download Fiddler here (please note: I have nothing to do with Telerik, it’s just a nice tool I use often). Go ahead and download the tool and we’ll move forward with the steps parsing JSON in Microsoft Flow
