Have you ever tried to get the all site collection details using Power Automate?

SharePoint Connector

After yesterday’s news about the new actions in the SharePoint Connector, today I thought I’ll try and take this a step further.

The challenge I gave myself is can I get to all the site collections and collect the details of my site collections using a flow? the answer is yes!

Get to all your site collection details with the REST API

First of all I found a list that contains all the site collection information for my tenant.

The api to get to this is:


So I added this uri to my Send an HTTP request to SharePoint action

Get to all your site collection details

And well the rest is easy!

Get to all your site collection details within your Office 365 tenant using Power Automate? Microsoft Office 365, Microsoft Flow sitecollectiontitles

As you can see above it is possible to display the Title of my site.

But you can get to more:

"FileSystemObjectType": 0,
"Id": 1,
"ServerRedirectedEmbedUri": null,
"ServerRedirectedEmbedUrl": "",
"ContentTypeId": "0x010038A268F2641BCA4FA94C95C6CD37607A",

Things like Modification dates, HubSiteId and Site Owners are extracted within no time. And how about Storage Used? All of this information could come handy one day.

  1. This is interesting! Can you please let me know how to get the list that contains all the site collection information for my tenant.

  2. DO I need to have global admin privileges to get this list? My account just has SharePoint admin rights and I donot see an empty title list. However I see this: DO_NOT_DELETE_SPLIST_TENANTADMIN_AGGREGATED_SITECOLLECTIONS. Can you please suggest?

  3. I have found that list now! But the result is empty array. I am pretty sure I am using the current URL and there are thousands of site collections in our tenant. Can you help me on this?

    1. I think that you have the wrong list.
      When you go to :

      You should see quite a few entries like this:
      href=”Web/Lists(guid’8822a3c0-3099-4942-9a25-caa23dec131c’)” />

      One of these lists is the one you are looking for.

      so I go through each one of these and visit the following url:


      then keep replacing the guid in that url until you get items back that include your site titles:

      In my browser output when visiting the above url I search for Title and find something like this:


  4. Body
    “d”: {
    “results”: []

    I see the output for Send Http request to Shareoint as above. Is this the expected result? Really appreciate your time and helping me out.

  5. I am able to get the result. However I am trying to get the site collection owner names for all of the site collections retrieved. Is this possible using FLOW?

      1. Thank you for the response. Its actually the members in the owner group of a site that I am looking for.

  6. Hi Pieter, can you show us how you build the rest of the flow from the Compose to the end? At the moment I don’t understand how you extract the Ttile out of the HTTP response and put them in an array.

      1. Thanks, I used the triggerbody() expression in the Compose action but ater running the flow the input and output is empty. The output of Send HTTP request to Sharepoint however show the same results as when I visit /_api/Web/Lists(guid’8f287b97-a3a2-4b64-9b82-c313c9480235′)/Items.
        What am I missing?

      2. the triggerbody function will give you the output from the trigger only.

        If you want to get the output from the HTTP request action you will need to use something like:


        The name of the HTTP request action may of course vary, and you will need to adjust that.

  7. Great post, this is so useful and easy to setup. I am bumping into one problem, I only get 100 items (sites) returned. Is there a limit on the http request?

    1. Have you tried adding this to the url:


      The default is 100 items, but you should be able to increase the number of items returned by specifying the top

  8. Hi ,
    Is there any possible to create a new site collection under main site collection. Please kindly let me know.

    Thanks & Regards

  9. I’d like to get the sub sites name and its URL of my root site collection which are created based on date parameter passed. If i passed today’s date then i need to get the sub sites created today. Could you please help how to achieve that?
