n8n-nodes-allsign

Create and send documents for electronic signature directly from your n8n workflows using the AllSign API V2.

🇲🇽 Español: Integración de n8n para firma electrónica con AllSign. Crea y envía documentos a firmar directamente desde tus workflows de n8n.

✨ Features

📄 Document — Create & Send

Upload a PDF or DOCX (from URL or binary input) and send it for signing in one step, with full control over signature requirements.

🇲🇽 Sube un PDF o DOCX (por URL o desde otro nodo) y envíalo a firmar en un solo paso, con control total sobre los requisitos de firma.

📱 Signers: Email & WhatsApp

Signers can be reached via email, WhatsApp, or both. When both channels are provided, the signer verifies their identity through OTP on both channels as part of the signing process.

• ✅ Email-only signers
• ✅ WhatsApp-only signers (phone number, no email required)
• ✅ Both channels — dual OTP verification during signing

🇲🇽 Los firmantes reciben invitaciones por email, WhatsApp o ambos. Cuando se proporcionan ambos canales, el firmante verifica su identidad por OTP en ambos como parte de la firma.

🔐 10 Signature Validations

| Validation | Description | | -------------------------- | -------------------------------------------------------------------- | | Autógrafa | Handwritten digital signature with biometric capture (on by default) | | FEA | Advanced Electronic Signature — Firma Electrónica Avanzada (Mexico) | | eIDAS | European Electronic Signature — eIDAS compliance | | NOM-151 | NOM-151-SCFI certified timestamping (Mexico) | | Video Signature | Recorded video of the signer during the signing process | | Biometric Selfie | Face comparison against the signer's government ID | | SynthID (AI Detection) | Verifies selfie is from a real person, not AI-generated | | ID Scan | Government-issued ID scan (INE, passport, etc.) | | Identity Verification | AI-powered ID + selfie verification pipeline | | Confirm Name | Signer must type their full name as confirmation |

📥 File Input

• Binary Input — Use a file from a previous node (e.g. Google Drive, HTTP Request, Dropbox)
• URL — Provide a public URL to a PDF or DOCX file (Google Drive and Dropbox links are auto-converted)

📐 Signature Field Placement

Place signature fields precisely on the document:

• By anchor text — Search for text in the PDF and place the field there
