Verify multiple signatures

GroupDocs.Signature Cloud provides a method to verify if the signatures with given properties are present in a document. The result of verify method contains boolean value IsSuccess (true or false).

API usage

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

  1. Upload input document into cloud storage
  2. Verify signatures

For storage operations, like uploading or downloading documents, please refer to the corresponding articles of this manual.

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