You can protect a deliverable with password encryption by including a password property in your request. Recipients must enter the password to open the PDF. The deliverable PDF is encrypted with AES-128 encryption.
Deliverable (Request)
{
    "type": "standard",
    "password": "SecurePass123",
    //...
}
Password protection must be enabled on your account before use. Contact support to enable this feature.

Password Requirements

  • Between 4 and 32 characters
  • Uppercase letters (A-Z), lowercase letters (a-z), and numbers (0-9) only
