Change a SharePoint Site Collection's Property via Power Automate

[skarthanal]

I am trying to figure out a way to change a SharePoint Site Collection's sharing property as shown in the screenshot.  I want to change it from the default (Only People in your organization) to (People with existing access).  I can do this via Powershell but wanted to know if it is possible via Power Automate?

Hi @skarthanal,

As far as I am aware setting it is not possible to set the default link type setting for an individual site collection via the REST API.

Invoking a site design with a site script for external sharing settings would be possible via the REST API and a HTTP action:

Thank you for replying @Expiscornovus.  I followed the links but i am not fully understanding how to achieve what i need. My PS script is below:

Connect-SPOService -Url "web url"

Set-SPOSite -Identity "web url" -DefaultLinkToExistingAccess 1

When i create the JSON body how do i verify that the property is "DefaultLinkToExistingAccess"?

@skarthanal , sorry, I wasn't entirely clear in my previous post. I basically said it was not possible (as far as I am aware).

I only showed how you could set the main sharing settings via a flow. But example doesn't allow you to set the value of the defaultlinktoexistingaccess attribute.
