Ensure the authenticity of collected signatures with a simple API parameter

To satisfy the requirements of certain industries for the uniqueness and immediacy of electronic signatures, the airSlate SignNow API allows you to add the "force_new_signature" parameter in the request body of your embedded eSignature invite. As a result, signers will be required to log in and manually create a new signature instead of re-using their saved signature.
