Key features of Docusign eSign API

The Docusign eSign API provides a wide range of features for developers to integrate secure electronic signatures and document management directly into applications.

Key features include:

1. Signature requests

Users can initiate and manage signature requests programmatically using the Docusign eSign API. Here’s how it simplifies signing workflows for developers:

Email invitations: Upload a document, specify recipient email addresses, and send it programmatically. Recipients receive an email with a link to sign the document — no additional configuration required.
Bulk sending: Send the same document to multiple recipients (e.g. company policy updates) in one API call with bulk sending. Upload a list of email addresses, and the API automatically handles the distribution and tracking for each recipient.
Embedded signing: Seamlessly embed the signing process into your app or website. Users can complete signatures without ever leaving your platform, creating a frictionless experience.

Managing signature requests is also easy with the Docusign eSign API. It allows users to:

Progress tracking: Monitor the status of each signature request in real-time via API calls. Know who has opened, signed, or not yet signed the document without manually following up.
Reminders: Automate follow-ups for eSignatures using the API to trigger reminders, ensuring no delays in workflows.
Send custom notifications: Set up notifications to alert you when a document is signed or if there are any issues. This way, you are always informed about the status of your documents.

With Docusign eSign API, developers can streamline the document preparation process:

Direct uploads or cloud integration: Upload documents from a server, or pull them from cloud storage platforms like Google Drive, Dropbox, and OneDrive.
Dynamic document generation: Generate documents on the fly by populating templates with user-specific data, creating personalized and professional-looking documents.
Dynamic field placement: Use API calls to place fields (signatures, dates, text, checkboxes) programmatically, or integrate with Docusign’s drag-and-drop functionality.
Reusable templates: Automate repetitive workflows by creating templates programmatically. Templates store pre-defined field placements and settings, reducing manual effort.

3. Real-time status tracking
