In this blog post I am going to show how it is possible to add and remove users to a SharePoint site using Microsoft Lists and Power Automate. I’ll be using the Send an HTTP request to SharePoint action throughout the Flow. “Send an HTTP request to SharePoint” constructs and executes SharePoint REST API calls. I’m not a developer, so a lot of my HTTP request calls are the result of “Googling” and banging my head against the wall.
Our site, called “SharePoint Demo”, has a List called “Users” with the following column definitions:
| Column | Type |
| User | Person. |
| Action | Choice with “Grant” and “Revoke” as the lookup values. |
| Group | Choice with “Visitors”, “Members” and “Owners” as the lookup values. This coincides with the default site security groups and can customized as you see fit. |
| SiteName | Single line of text. |
At a high-level our Flow triggers from new or edits to the Users list and either adds or removed the user from the SharePoint security group. Security group is based on a combination of “SiteName” and “Group”. For example “SharePoint Demo Visitors”.
Create a new Flow from the Users list > Automate > Power Automate > See your Flows > Create new > Automated from blank. Provide a Flow name, i.e. “SharePoint – Add/Remove Users”, select the SharePoint “When an item is created or modified” trigger and click “Create”.
Set the trigger to your target site and list name.
Insert a new “Initialize variable” step. Set Name to “varSiteName”, Type to “String” and Value to “SiteName Value” from the “When an item is created or modified” trigger.
Insert a new “Send an HTTP request to SharePoint” step. Set:
- Site Address to your target site.
- Method to “GET”.
- Uri to
"_api/web/SiteGroups?$filter=LoginName eq '@{concat(variables('varSiteName'), ' ', triggerOutputs()?['body/Group/Value'])}'&$select=Id&$top=1". - Headers to
{ "accept ": "application/json;odata=verbose", "content-type": "application/json;odata=verbose" }
Save your Flow and test by adding a new entry to Users list.
Copy the “body” from the OUTPUTS section of the “Send an HTTP request to SharePoint – Get Group ID” step.
Insert a new “Parse JSON” step. Set Content to “body” from the “HTTP request to SharePoint – Get Group ID” step. Click “Generate from sample” and paste in the “body” from the OUTPUTS section of the “Send an HTTP request to SharePoint – Get Group ID” step.
Insert a new “Condition” step. Set Choose a value to “Action value” from the “When an item is created or modified” trigger, “is equal to”, “Grant“.
In the “If yes” branch, insert a new “Send an HTTP request to SharePoint” step. Set:
- Site Address to your target site.
- Method to “POST”.
- Uri to
"api/web/SiteGroups(@{items('Apply_to_each-_Add_User')?['Id']})/users". Where “Id” is from the Parse JSON action. Power Automate will create an “Apply to each” action automatically. - Headers to “
{ "accept ": "application/json;odata=verbose", "content-type": "application/json;odata=verbose" }“. - Body to “{ “__metadata”: { “type”:”SP.User” }, “LoginName”:”@{triggerOutputs()?[‘body/User/Claims’]}” }”. Where “User Claims” is from the “When an item is created or modified” trigger.
Insert a new “Condition” step. Set Choose a value to “Action value” from the “When an item is created or modified” trigger, “is equal to”, “Revoke“.
In the “If yes” branch, insert a new “Send an HTTP request to SharePoint” step. Set:
- Site Address to your target site.
- Method to “GET”.
- Uri to
"api/web/SiteGroups(@{items('Apply_to_each-_Remove_User')?['Id']})/users/GetByEmail('@{triggerOutputs()?['body/User/Email']}')". Where “Id” is from the Parse JSON action and “User Email” is from the “When an item is created or modified” trigger. - Headers to “
{ "accept ": "application/json;odata=verbose", "content-type": "application/json;odata=verbose" }“.
- Insert a new Compose action and set Inputs to “Body” to the following expression “
@{body('Send_an_HTTP_request_to_SharePoint_-_Get_User_Id')['d']['id']}“. Hint: “Send an HTTP request to SharePoint – Get User Id” step.
Insert a new “Send an HTTP request to SharePoint” step. Set:
- Site Address to your target site.
- Method to “POST”.
- Uri to
"api/web/SiteGroups(@{items('Apply_to_each-Remove_User')?['Id']})/users/removeById(@{outputs('Compose-_User_Id')})". Where “Id” is from the Parse JSON action and “Outputs” is from the “Compose – User Id” trigger. - Headers to “
{ "accept ": "application/json;odata=verbose", "content-type": "application/json;odata=verbose" }“.
Test by creating new or modifying entries in the Users list.
I like this Flow pattern for automatically provisioning site security on behalf of non-technical site owners where the security groups may not be so straight forward. Adding approval workflows would be a natural next step with this Flow.

Hi Norm,
When we try to use this expression @{body(‘Send_an_HTTP_request_to_SharePoint_-_Get_User_Id’)[‘d’][‘id’]} under compose, we are getting below error:

Thanks for sharing. I originally wanted to work around the fact that SPO groups do not allow to add groups in a group while other systems accept this. In my case, I have to add a user to several groups, including one that contains all groups. I thought using a list to add users in each ad hoc group using your method would be a good workaround however I am not confident to spend less time to creates this PA and list than add a newcomer to several groups. I wish Microsoft will finally upgrade user groups management to have the features add a user or a group in a group, sort users by a column, allow viewing some additional columns or mask the user description column or add the feature sort. Then User group will be as Lists and more user-friendly. I bookmark your method in case I get the courage to bang my head and go through all Microsoft’s gymkhana

Hi Norm,
I am trying to trigger the flow whenever an entry is made in my SQL table.
I need to add the new users into their respective security groups. When the entry is made, one of the columns contain a HubIDs which is string type column and contains IDs which are a foreign key from Hub table which has the ids and names of the hubs(security groups) that the user is supposed to be a part of. These are not actual security group IDs. So I need to add the new user into the security groups that are assigned against his name in SQL table. I’m not much familiar with REST api and json, hence having a hard time trying to reach the output. And I couldn’t find anything related to such a problem statement. Yours is the closest solution I have found yet.
If possible could you help me out?

Hi Norm,
I have to create a SQL trigger whenever an item is added to the Users table to perform an action when the new user is entered, they should be directly added to their respective security group. Users table consists of Name, Email and SecurityGroupId in which the user needs to be added. The name of the security groups are in another table and securityGroupId acts as connection between these 2 tables. So I need to use the securityGroupId and find the name of the sharepoint security group where the new user is to be added. I’m very new to sharepoint as well as automate. Could you help me out a little here?

I am trying to do something similar to your original post. I am trying to add a user to a newly created item by looking them up from another list. The newly created item is a result of another flow when a user adds a document to a library. I’m not a developer, so I haven’t been able to get the http request calls to work.

Hi Steve,
Are you trying to grant item-level permissions to the user who added the document to the library or are you trying to add the user to a column in the list item that tracks the document added to the library?

Hi Martin,
It looks like an unexpected character was added to the source code as %22. I believe that is a quote. Removing the quote and try again.

This is the body, I think everything is correct. (I’m no using the conditios tho, it’s a flow to add user only)

“LoginName”:”@{items(‘Apply_to_each_2’)?[‘Claims’]}”
