Create an embedded signing session with pre-filled signature fields and enable or disable signature editing

Pre-filling a signature field with a recipient's name and disabling signature editing is a great way to protect a signed document from unwanted errors or tampering. The signer’s name will appear in the document where they can either confirm their signature or decline the eSignature invite. However, you can also allow signers to edit their signatures if your security policy permits it.
