Errors

Unsupported Recipient Type

Error

What Happened

Legacy signature placeholders only work with recipients of type signer. The document uses legacy signature placeholders, but one or more recipients have a different type.

The response includes a detail property with more information about this error.

How to Fix

  • Update the recipient type to signer if they need to sign using legacy placeholders.
  • Alternatively, upgrade to generic placeholders, which support all recipient types.
