Protect your deliverable with a password

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.

{
    "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
Special characters are not supported due to PDF reader compatibility

For strong protection, use at least 12 characters with a random mix of uppercase letters, lowercase letters, and numbers.
