Get list of changes of comparings

GroupDocs.Comparison Cloud allows to obtain list of changes between source and target files.

The following code sample demonstrates how to get list of all changes.

API usage

There are steps that usage of GroupDocs.Comparison Cloud consists of:

  1. Upload input documents into cloud storage
  2. Compare documents or get document info
  3. Download comparison result document from storage

Steps 1 and 3 are storage operations, please refer to this File API documentation for usage details.

Swagger UI lets you call this REST API directly from the browser.

cURL example


* First get JSON Web Token
* Please get your Client Id and Client Secret from https://dashboard.groupdocs.cloud/applications. Kindly place Client Id in "client_id" and Client Secret in "client_secret" argument.
curl -v "https://api.groupdocs.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=xxxx&client_secret=xxxx" \
-H "Content-Type: application/x-www-form-urlencoded" \

SDK example

Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of GroupDocs.Comparison Cloud SDKs along with working examples, to get you started in no time. Please check Available SDKs article to learn how to add an SDK to your project.
