  • Follow the exact route shown above and verify the stored record, generated file and delivery evidence instead of relying on an alert alone.

What this guide covers

Use the signature pad and send the base64 PNG to the acceptance endpoint. These instructions follow the inspected module’s live hook, route, controller, model, installer, PDF helper and view flow.

Exact step-by-step process

  1. Draw the signature on the canvas.
  2. Use Clear Signature if a redraw is needed.
  3. Select Accept & Sign Document.
  4. If the canvas is empty, draw a signature and submit again.
  5. Wait for the signed confirmation state.

EvidenceVerify the history row, PDF, email metadata, open evidence, signature, public page, client view or postal fields produced by this flow.

Code-backed validations and workflow rules

  • Signature Pad 4.0.0 is loaded from jsDelivr.
  • Client-side JavaScript converts the canvas to a PNG data URL.
  • The controller strips the data URL prefix, base64-decodes the data and writes a PNG file.

Expected result and verification

  • The requested letter, template, setting, file or tracking detail is created or updated through the supported route.
  • The history row, generated PDF, email/send metadata, public verification, signature evidence, client view or postal display agrees with the action.
  • Any warning, missing file or failed send is investigated rather than bypassed.

Security, privacy and operational checks

  • Apply least privilege and verify recipient identity before sending or exposing public links.
  • Protect PDFs, enclosures, signatures, verification URLs, email-open metadata, IP addresses and customer data under organisational policy.
  • Test configuration and deployment changes with controlled records before production-wide use.
  • Interpret email opens and e-signatures according to their documented technical limitations.
