Getting List Attachment Information



I am building a Flow so that when a list item is created, it will send an email to include links to the item attachment files, that says that I will need to return file name and path.


In SharePoint Designer workflow, I can call REST web service to expand the AttachmentFiles field to get such details, and it looks like that I can do the same with HTTP action in Flow, but I don't know how to fill out the Authentication,  can someone show me an example ?

Hi @manlamcheng,


Please switch to Custom API (Custom connectors) instead of using the Http Action (which should not support the authentication type used in SharePoint, see posts from Samuel in this thread).

For custom connectors, check:

Register and use custom connectors in Microsoft Flow

Working with Lists and list items with REST


Besides, add an idea about suggest to add the attachments support for SharePoint List items:

Create attachments and list attachments from SharePoint Online List Item
