How to Add Comments to SharePoint List Items Using Power Automate?

Problem Statement: I am trying to add comments to a SharePoint list item using Power Automate. For this, I used the "Send an HTTP request to SharePoint" action. However, my flow fails with the following error:

Action 'Send_an_HTTP_request_to_SharePoint-copy' failed: {"odata.error":{"code":"-1, Microsoft.SharePoint.Client.ResourceNotFoundException","message":{"lang":"en-US","value":"Cannot find resource for the request Commnets."}}

Steps I Took:

1. I created a flow in Power Automate.
2. I added a "Send an HTTP request to SharePoint" action with the following settings:

• Site Address: <Your Site URL>
• Method: POST
• Uri: _api/web/lists/getbytitle('Project Tracker')/items(<Item ID>)/Comments
• Headers:
• Content-Type: application/json
• Body

{
    "text": "This is a comment."
}

The error suggests that the resource "Commnets" cannot be found. I double-checked my endpoint URL, but the issue persists.

1. What am I doing wrong?
2. Is there a different API endpoint I should use for adding comments to SharePoint list items?
3. Are there any specific permissions required for this action?

• I am working with a modern SharePoint Online list named "Project Tracker."

• I have full control permissions on the list.

Any guidance or suggestions would be greatly appreciated. Thank you!

After investigating, I discovered the issue was caused by a typo in the endpoint URL. I had written Commnets instead of Comments. Correcting the typo resolved the issue.

Here’s the corrected configuration that worked for me:

HTTP Request Configuration

Method: POST

Endpoint:

_api/web/lists/getbytitle('Project Tracker')/items('ItemID')/Comments

Headers:

{
    "accept": "application/json;odata=verbose"
   
}

Body:

{
    "text": "This is a new item."
}
