Sign document with text signature

A Text electronic signature is an arbitrary text that is added to a document in a native way dependent on document type. GroupDocs.Signature Cloud provides text signature feature and allows to customize wide range of text settings - from font name, size and color to alignment, borders, shadow effects etc. This is how text signature may look like:

text

To manipulate with text signatures GroupDocs.Signature Cloud provides various text sign options.

API usage

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

  1. Upload input document into cloud storage and other files, like digital certificate or image stamp
  2. Sign document
  3. Download output document

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.
