Update a hyperlink or picture column in SharePoint using Microsoft Power Automate (Flow)

Setting a hyperlink column’s value using Power Automate is a bit different than setting other column types’ values. In SharePoint, a hyperlink column has two components – address and description. If you update this column type using Power Automate’s “Update item” action, your address and description are both set to the same value.

In SharePoint Designer workflows, we could do this easily with the usual “Set field” action:

But in Power Automate, we only get one field which maps to the URL/address part of the hyperlink field, and is duplicated as the description as well in SharePoint.

And if you’re thinking it could work with a comma, as some other field types might, it won’t. You’ll get “Enter a valid uri.”

To get this to work so we can set both address AND description as separate values, we have to use an HTTP request action instead of (or in addition to) the Update item action. This isn’t as complicated as it may sound. Here are the steps:

1. Add the Send an HTTP request to SharePoint action

2. Choose or enter your site for Site Address

3. Set Method to POST

4. Set the Uri to the following, changing List Name to your list’s name, and replacing [ID] with the ID field from dynamic content

_api/web/lists/GetByTitle('List Name')/items([ID])

5. The easiest way to set your headers is to copy and paste this text into the “Text mode” option as demonstrated in the GIF that follows.

   "Content-Type": "application/json;odata=verbose",
   "X-HTTP-Method": "MERGE",
   "IF-MATCH": "*"

6. Lastly, in Body, you can copy and paste this as well, but:

  • replace List_x0020_Name with your own list’s name. _x0020_ should replace any spaces in your list name.
  • replace Hyperlink with the name of the hyperlink column’s name
  • replace Google with the label/description/clickable text you want for the hyperlink
  • replace http://www.google.com with the URL/address part of the hyperlink
{'__metadata': {'type':'SP.Data.List_x0020_NameListItem'},'Hyperlink':
 {'Description': 'Google',
 'Url': 'http://www.google.com'}

Your final result should resemble this:

Test that out. When it’s working and you’re ready to take it to the next level, you can replace the static url (like Google’s in my example) with dynamic content. For example, you could create convenient one-click links to an item’s version history:

  1. Thank you, this post was tremendously helpful!

    One thing I would add is, if the list name has been changed, you have to use the current list name in the api field but the original list name in the body. The column name in the body has to be the internal SharePoint column name. That is what got it to work, for me, anyway.

  2. I tried this and it worked, then I changed the name of the column and did not work again. Now I am getting the following error: The property ‘Description’ does not exist on type ‘SP.File’. Make sure to only use property names that are defined by the type.

  3. Hey I tried this out and it was working! But then it all of a sudden wasn’t. I changed the name of the list but also changed it in the flow. I’m not a coder so I’m not sure why I’m getting this error now or what it means:

    “A type named ‘SP.Data.Asset_x0020_ApprovalsListItem’ could not be resolved by the model. When a model is available, each type name must resolve to a valid type.”
