In this post, I will show you how to create a DateTime type filed in a SharePoint Online list using Power Automate flow action.
To implement this demo we will use the “Send an HTTP request to SharePoint” action

Site Address:
| https://{site}.sharepoint.com/sites/{SiteName} |
Method:
POST
Uri:
_api/web/Lists/getByTitle('{ListName}')/fields
Headers :
{ "content-type": "application/json;odata=verbose", "Accept": "application/json;odata=verbose" }
Body :
{
'__metadata': { 'type': 'SP.FieldDateTime'},
'FieldTypeKind': 4,
'Description': '{Field Description}',
'Title': '{Field Name}',
'DisplayFormat': 0
}
The screenshot below depicts an example
