Send http request to sharepoint to create subsite, and set default owner, member groups


23 October 2018

08:58 AM


I am using flow and send HTTP request to Sharepoint to provision some subsites, going for a non azure /pnp option if I can.


I create a subsite in a SharePoint online using the method posted below via REST API / Flow

However the UseUniquepermissions has two values, true or false.

If its false it inherits the parent permissions / groups as expected.

If its false you just get an empty Sub site and no site groups.


I want to replicate the ability of _layouts/15/permsetup.aspx where you can create specific owner, member, visitor groups of the subsite

So whilst I can manually create the standard owner, member , visitor groups and mimic them there is no way I have found to set one of these as the default associated groups via REST API. AssociatedOwnerGroup, AssociatedMemberGroup etc Lots of people say GET works but POST / MERGE doesn’t)


So either I require the ability to set a default group via REST API would suffice (this just helps out when people share the site as it will default to the appropriate group), or the ability to somehow set the out of the box associated groups AssociatedOwnerGroup, AssociatedMemberGroup etc would be good all via REST API.


Any help appreciated as this is my last stumbling block!
