MerchantKits Document Signatures lets you add a signature collection form to any page or post using a simple shortcode. Signers can draw their signature on a canvas or type it using a cursive font. Every signature is recorded with a SHA-256 integrity hash, signer IP, user agent, and timestamp — giving you a complete audit trail.

Key Features

Draw or type — configurable per form or globally in settings.
SHA-256 audit hashing — every signature generates a unique integrity hash.
IP & User Agent capture — complete audit trail for every signing event.
Admin dashboard — stat cards, recent activity, and quick-start guide.
Document management — create signable documents and link forms via shortcode.
WP_List_Table — sortable, filterable, searchable signatures list with CSV export.
Email notifications — automatic confirmation to the signer and notification to the admin.
REST API — full CRUD endpoints under wpsv/v1.
Theme-overridable templates — place your own wpsv/signature-form.php in your theme.
Works anywhere — drop the shortcode on any page, post, or order confirmation.

Shortcode Usage

[wpsv_signature]

Attributes:

document_id — links the form to a saved document.
title — heading shown above the form.

Privacy / External Services

All signature data (images, hashes, signer information) is stored in your own WordPress database. The plugin does not send signature data to any external server.

The draw-mode signature canvas is powered by Signature Pad (MIT License), which runs entirely in the visitor’s browser.
