Yousign offers several signature levels in compliance with the eIDAS requirements and the law in European countries, for all your documents.

Each signature level offers additional security and legal weight to ensure optimal risk management.

There are three different levels of eSignature:

• Simple eSignature, useful for online signatures for your daily work
• Advanced eSignature, to secure signatures for your sensitive documents
• Qualified eSignature, which is the legal equivalent of a handwritten signature

Learn more about the three signature levels in this guide.

Define my signature level:

The signature level is specified at the signer's level. The signature level must be set in the signature_level property in the signer payload. All Signers must have the same signature level.

How to set the signature level?

The signature level is specified at the Signer's level. The signature level must be specified in the signature_level property in the Signer payload. You will find below a payload example for a Simple eSignature level :

{
  "info": {
    "first_name": "John",
    "last_name": "Doe",
    "email": "[email protected]",
    "phone_number": "+33760047242",
    "locale": "en"
  },
  "signature_level": "electronic_signature",
  "signature_authentication_mode": "no_otp",
  "fields": [
    {
      "document_id": "{{documentId}}",
      "type": "signature",
      "page": 1,
      "width": 180,
      "x": 400,
      "y": 650
    }
  ]
}
