Send HTTP Request to Sharepoint: Quirks!

Starting this thread here to share some of the quirks I've come across with the "Send an HTTP Request to Sharepoint" Action. I'll add to it as more things pop up.


  1. Create Sharepoint List POST request:
    1. Headers:
      1. If you use...
        1. content-type: application/json;odata=verbose
      2. must specify the __metadata object in the JSON body...
        1. {
              '__metadata': { 'type': 'SP.List' }, 
              'AllowContentTypes': true,
              'BaseTemplate': 100,
              'ContentTypesEnabled': true, 
              'Description': 'My first test list', 
              'Title': 'The coolest list ever'
      3. If you use...(notice the colon and the double quotes)
        1. content-type: "application/json;odata=verbose"
      4. You must remove the __metadata object from the body!!
        1. {
              'AllowContentTypes': true,
              'BaseTemplate': 100,
              'ContentTypesEnabled': true, 
              'Description': 'My first test list', 
              'Title': 'The coolest list ever'
        2. Otherwise the Flow will fail with the message: Status 400, Bad Request...
        3. {
            "message": "The property '__metadata' does not exist on type 'SP.List'. Make sure to only use property names that are defined by the type.\r\nclientRequestId: 4c16565b-cf95-42d9-9d9e-ddc2a5b01dec\r\nserviceRequestId: 2c680f9f-0032-0000-4762-24578c3e6a56",
            "status": 400,
            "source": "",
            "errors": [

Hows that for quirky?

Re: Send HTTP Request to Sharepoint: Quirks!

I have a quirky one when trying to add to sharepoint navigation:




It only works with the following which ends up meaning i need to go back in and delete junk out of the URL if you put the full url i.e. https:// flow does some funky stuff and trys to be too smart ! 😞


"__metadata": { type: "SP.NavigationNode" },
   'IsExternal': false,
      'Title': "@{triggerBody()?['Title']}",
        'Url': "//{triggerBody()?['ID']}"

Hi @yapper ,


Thank you for your sharing!

Please check this blog and get more details about SharePoint / Microsoft Flow – Maintain List details for no-code developers:


The interaction between Headers and JSON Body is not specified by MS Flow. Send HTTP Request to SharePoint action only provides a configurable interface to help users edit the request. The specific configuration needs to be referenced in the SharePoint REST API.
