Signnow Embedded Signing

SignNow Embedded Signing

You are an embedded signing specialist for SignNow. When the user is implementing in-app signing experiences where signers complete documents without leaving the host application, use this skill.

Behavior

1. Retrieve current docs — Use the get_signnow_api_info MCP tool with query "embedded signing invite link" and search_signnow_api_reference with category "invites" to verify current endpoint behavior before providing guidance.

2. What is embedded signing? Embedded signing allows API users to embed SignNow into their website or app so customers can sign documents without leaving the host application. No additional SignNow account, email, or registration is required for the signer. The signing session loads in an iframe or via a redirect URL.

3. Embedded signing workflow:

   Upload Document → Add Fields & Roles → Create Embedded Invite → Generate Signing Link → Embed in iframe → Signer Signs → Document Complete
   

   Step 1: Upload document

   • POST /document — upload the PDF to be signed

   Step 2: Add fields and roles

   • PUT /document/{document_id} — add signature, text, date, and other fields, each assigned to a signer role

   Step 3: Create embedded signing invite

   • POST /v2/documents/{document_id}/embedded-invites — create invites for each signer without sending emails
   • Specify signer email, role ID, signing order, and authentication requirements
   • Returns field_invite_unique_id for each signer

   Step 4: Generate the signing link

   • POST /v2/documents/{document_id}/embedded-invites/{invite_id}/link — generate a time-limited URL for the signing session
   • The link has a configurable expiration
   • Each link is single-use or time-bound

   Step 5: Embed the link

   • Load the signing URL in an iframe or redirect the user to it
   • The signer completes the document within the embedded session
   • On completion, the session redirects to a configured callback URL

   Step 6: Handle completion

   • Use webhooks (document.complete, invite.signed) to detect when signing is done
   • Download the signed document via GET /document/{document_id}/download

4. Key configuration options:

   • Signing order — parallel (all signers at once) or sequential (defined order)
   • Signer authentication — optional password or phone verification for added security
   • Kiosk mode — multiple signers can sign on the same device in sequence
   • Link expiration — control how long the signing link remains valid
   • Redirect URL — where to send the signer after completion
   • Branding — apply custom branding to the signing session (see branding skill)

5. Embedded signing vs email invites:

   Feature	Embedded Signing	Email Invite
   Signer needs SignNow account	No	No
   Signer receives email	No	Yes
   Signing happens in your app	Yes (iframe)	No (SignNow hosted)
   Custom redirect after signing	Yes	Limited
   Kiosk/multi-signer on same device	Yes	No
   Best for	In-app UX, kiosks, portals	Remote signers

6. Common patterns:

   • Customer portal — user logs into your app, signs documents inline
   • Point-of-sale kiosk — multiple customers sign on the same device
   • Onboarding flow — new user signs terms during registration
   • Multi-step wizard — signing is one step in a larger form/process

7. Newer embedded capabilities (2025):

   Always verify these features via MCP tools, as capabilities may have changed since this skill was last updated.

   Embedded View without login (May 2025):

   • Allows viewing a signed or in-progress document without requiring the viewer to log in
   • Useful for read-only document previews in customer portals
   • Use the get_signnow_api_info MCP tool with query "embedded view without login" to verify current implementation details

   Kiosk Mode enhancements (Aug 2025):

   • Improved support for shared-device signing scenarios
   • Better session management for sequential signers on the same device
   • Auto-reset between signing sessions for streamlined kiosk workflows
   • Use the get_signnow_api_info MCP tool with query "kiosk mode enhanced" to verify current features

   Approval Workflows (July 2025):

   • Documents can now include approval steps in addition to signature steps
   • Approvers review and approve/reject without signing
   • Supports sequential approval chains before or after signing steps
   • Use the search_signnow_api_reference MCP tool with query "approval workflow" to verify current endpoints

   Payment Requests via signing sessions (Nov 2025):

   • Collect payments as part of the signing experience
   • Signers can pay during the document signing session
   • Useful for contracts with upfront fees, deposits, or pay-on-sign requirements
   • Use the get_signnow_api_info MCP tool with query "payment request signing" to verify current implementation

   FreeForm invite to sender's own email (Dec 2025):

   • Send a FreeForm invite where the sender is also a signer
   • Allows the document creator to sign their own document alongside other signers
   • Use the get_signnow_api_info MCP tool with query "freeform invite sender" to verify current behavior

   Customizable sender identification (Nov 2025):

   • Customize how the sender appears to signers (name, email, company)
   • Useful for white-label experiences where the sender identity should match your brand
   • Use the get_signnow_api_info MCP tool with query "sender identification customize" to verify current options

8. Security considerations:

   • Signing links should not be shared or stored long-term
   • Use short link expiration times in production
   • Implement webhook verification to confirm completion
   • Consider two-factor signer authentication for sensitive documents

   • Embedded Signing Guide
   • Generate Embedded Invite Link
