Update a SharePoint Library Title and Description with Power Automate

Overview

Use Power Automate to update a SharePoint library or list title and description by calling the SharePoint REST API. This is useful when you want to automate metadata updates or rename a library from a flow.

Prerequisites

  • A Power Automate cloud flow with access to the target SharePoint site
  • A SharePoint library or list title to update
  • The Send an HTTP request to SharePoint action

Configure the SharePoint REST action

In the Send an HTTP request to SharePoint action:

  • Method: PATCH
  • Site Address: <SiteUrl>
  • Uri: / _api/web/lists/getByTitle('ListName')

PA Site Url

If you use a Power Automate variable for the list title, build the URI with an expression:

/_api/web/lists/getByTitle('@{variables('ListName')}')

Or use concat() to inject the variable safely:

concat('/_api/web/lists/getByTitle(''', variables('ListName'), ''')')

Required headers

Headers Url

Use these request headers:

Accept: application/json;odata=verbose
Content-Type: application/json;odata=verbose
If-Match: *

If-Match: * is required when updating list metadata. Without it, SharePoint may return an error such as:

The request ETag value ’’ does not match the object’s ETag value ‘“66”’.

Request body

{
  "__metadata": { "type": "SP.List" },
  "Title": "@{outputs('Library_Display_Name')}",
  "Description": " "
}
  • Title is the new display name for the library or list.
  • Description is the new description text.
  • If you only need to update the title, you can keep Description as an empty string or supply a new value.

Notes

  • This call updates list metadata only; it does not move files or change internal list IDs.
  • Ensure the list title passed to getByTitle() matches the existing library/list title exactly.
  • Use expressions to handle titles with quotes or special characters.
