Signing Envelopes

Signature Methods

SignSecure supports three signature methods:

Draw your signature using your mouse or touchscreen, or type your name and select a signature font. Works on desktop and mobile. 10 credits flat per envelope (charged once regardless of how many signers use this method).

Aadhaar eSign (OTP)

For envelopes requiring identity verification:

Enter your Aadhaar number
Receive an OTP on your Aadhaar-linked mobile number
Verify the OTP to apply a digitally signed signature

Costs 15 credits per signer.

Aadhaar eSign supports both coordinate-based and text-based signature placement. When text-based placement is used, the system automatically resolves the search text to page coordinates before sending to the Aadhaar provider.

DSC USB Token

Sign using a physical Digital Signature Certificate plugged into your computer. Requires the SignSecure Native desktop application to communicate with the USB token. 10 credits flat per envelope (charged once regardless of how many signers use this method).

All Methods

When a recipient is set to "All", they can choose any of the above methods at the time of signing.

Signature Placement

There are two ways to position signatures on the PDF:

Coordinate-Based Placement

Place the signature at exact (x, y) coordinates on a specific page. Works with all signature methods.

Text-Based Placement

Search for a text string inside the PDF and automatically position the signature above or below it. You can optionally limit the search to specific pages using the pages array.

`pages` value	Behaviour
omitted / `[]` / `[0]`	Search all pages
`[1, 3]`	Search only pages 1 and 3

Text-based placement works with both Electronic and Aadhaar eSign signature methods. For Aadhaar, the system automatically resolves text positions to coordinates before signing. DSC/USB requires coordinate-based placement.

Verification Methods

Method	Description
Link Only	Recipient clicks the signing link from their email (default)
Email Verification	Recipient must enter a 6-digit code sent to their email before signing

Email Notification Preference

The envelope creator can control when recipients receive email notifications:

Preference	Behavior
All Emails	Emails at every step -- signing requests, next-signer alerts, reminders, and completion (default)
Completion Only	Only a completion email is sent when every recipient has finished
No Emails	No email notifications at all

When set via the API, use the workflow.emailNotifications field ("all", "completion_only", or "none").

Signing Flow

Recipient receives an email with a secure signing link (unless email notifications are disabled)
Open the link to view the envelope
Fill in any required form fields assigned to you
Apply your signature using your preferred method
Confirm and submit

Recipient Roles

Role	Action Required
Signer	Must sign the envelope
Approver	Must approve (no signature drawn)
CC	Receives a copy, no action needed

After Signing

When all recipients complete their actions:

The envelope status changes to Completed
All parties receive a notification
The signed PDF is available for download
The audit trail is finalized

Redirect Back to Your App

If you create or send envelopes through the API, you can send signers and approvers back to your product after they finish.

Set workflow.redirectUrl to a full https:// or http:// URL when creating the envelope.

{
  "workflow": {
    "mode": "sequential",
    "verificationMethod": "link_only",
    "emailNotifications": "all",
    "redirectUrl": "https://app.example.com/signing-complete"
  }
}

SignSecure will redirect signers and approvers to this URL after they complete their action. The following query parameters are appended automatically:

Parameter	Description	Example
`envelopeId`	The envelope that was acted on	`abc123xyz`
`signerEmail`	Email of the person who signed/approved	`jane@example.com`
`role`	Recipient role	`signer` or `approver`
`status`	Always `completed`	`completed`
`event`	The action performed	`signed` or `approved`

Example redirect:

https://app.example.com/signing-complete?envelopeId=abc123xyz&signerEmail=jane%40example.com&role=signer&status=completed&event=signed

`emailNotifications` Values

Value	Description
`"all"`	Send emails at every step (default)
`"completion_only"`	Only send a completion email when every recipient has finished
`"none"`	Do not send any email notifications
