You can protect your deliverable with password encryption by including a password property in your request. When a password is set, recipients will need to enter it to open the PDF.
Deliverable (Request)
{
    "type": "standard",
    "password": "123456",
    // optional properties: language, timezone, timestamp_format, etc ...
}
For optimal compatibility with PDF readers, use a password that contains:
  • Uppercase letters (A-Z)
  • Lowercase letters (a-z)
  • Numbers (0-9)
We don’t allow special characters, as some PDF readers may not support them
The deliverable PDF is protected with AES-128 encryption. Its security depends entirely on the strength of the password you set. To ensure confidentiality, we recommend choosing a password that is:
  • At least 12 characters long (longer is stronger)
  • A random mix of uppercase letters, lowercase letters, and numbers.
  • Not based on dictionary words, patterns, or personal information
  • Unique to the deliverable
