Hi @dixonbridgeta,
You could update the StorageMaximumLevel field value via the Microsoft.Online.SharePoint.TenantAdministration namespace. This can be accessed via the _api/Microsoft.Online.SharePoint.TenantAdministration.Tenant
You would need to retrieve the site id. After that you can update that property value via a POST request.
Below is an example.
Be aware, that value is in MBs not GBs 😁
In this example I am setting the storage limit to 250 GB
URI
_api/Microsoft.Online.SharePoint.TenantAdministration.Tenant/Sites('@{outputs('Send_an_HTTP_request_to_SharePoint_-_Get_Site_Id')?['body']['Id']}')
Headers
{
"Accept": "application/json;odata=nometadata",
"Content-Type": "application/json;odata=nometadata",
"X-HTTP-Method": "MERGE"
}
Body
{
"StorageMaximumLevel": "256000"
}
