Sending an attachment from a SharePoint List using PowerApps

Hi Everyone:

Very new to Power Automate and PowerApps. Thank you for answering my question.

I have a list with a file attachment in a SharePoint List

In Power Apps, I have an email Icon and when it is clicked on, it will send an email with the attachment.

I am using Get Attachments and Get Attachment Content

In both of these items there is an Id field

And both, using Dynamic Content, the ID field does not show up

In my list, I know ID = 66 has an attachment

If I put 66 in both of these fields, it works!

But I don't what this hard coded, I want whatever list item is selected, it will pick up the ID and send that attachment

How do I pick up this ID?

Hey @ByteLogic,

The reason the ID is not showing in Dynamic Content is because your flow is triggered from Power Apps, not directly from SharePoint. So Power Automate doesn’t automatically know which list item you’re referring to , unless you pass that ID from Power Apps.
That’s why hardcoding 66 works, but it’s not dynamic.
Here’s what you should do:
In Power Automate

Use PowerApps (V2) as the trigger.

Add an input parameter (Number) — call it something like ItemID (Ask in PowerApps).

In both Get attachments and Get attachment content, set the Id field to that ItemID parameter instead of hardcoding 66.

In Power Apps
When calling the flow from your email icon, pass the selected item’s ID:
YourFlowName.Run(ThisItem.ID) (or Gallery1.Selected.ID if you’re using a gallery)

This way, the flow will always use the ID of the selected list item and pick up the correct attachment dynamically.

Let me know if you’d like help structuring the attachment array for the email step as well.

Hi,

In PowerApps, On Email Icon click: PowerAutomateFlow.Run(Gallery1.Selected.ID). This sends selected item ID to flow trigger parameter.

Flow trigger has Ask in PowerApps parameter. Use triggerBody()['number'] in "Get item" ID field use Gets full item details.

Use Get attachments from Site ID field: body('Get_item')?['ID'] from dynamic content. Now shows correct attachment for selected item.

Get attachment content same List ID: body('Get_item')?['ID'], File ID: body('Get_attachments')?['value']?[0]?['Id'].

Use Send Email and pass the Content of attachment and pass file name
Attachments field
Name: body('Get_attachments')?['value']?[0]?['Name']
Content: body('Get_attachment_content')?['body']

Note: For Multiple files
JSON Format Required
Attachments needs array format:

text
[
{
"Name": "filename.pdf",
"ContentBytes": "@{body('Get_attachment_content')?['body']}"
}
]

Thank you so much, Sam. I went your solution.

You were absolutely right when you said to change to Power Apps (v2), I had it at Manual Trigger.

But I did have to make a small adjustment to the Power Apps code:

OnSelect ='PowerAppV2->Getattachments'.Run({number:(ThisItem.ID)})

I am about to post another question about this flow, but I think it needs to go under a different title.
