MerchantKits Document Signatures

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

Attributes:

• document_id — links the form to a saved document.
• title — heading shown above the form.
• description — optional introductory text.
• button_text — submit button label.
• redirect — URL to redirect to after a successful signature.
• type — draw, type, or both (overrides global setting).

Example:

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.
