Special placeholders are four types of placeholders that are created automatically for every recipient. So, before placing special fields in your PDF contract, create a recipient using this request. After this, all the special placeholders will be created automatically with corresponding keys: Recipient_Key_1, Recipient_Key_2, Recipient_Key_3, Recipient_Key_4. Here’s an example of a placeholder key: "placeholderKey": "93447fb5-91ee-41ad-9f73-b4ae2d467292_4". Available placeholder codes:
  • 1: Recipient’s date signed.
  • 2: Recipient’s full name.
  • 3: Recipient’s email.
  • 4: Recipient’s signature.
