I am new to Salesforce and the Drawloop(Nintex for Salesforce). We currently have a workflow where the Quotes are auto generated and converted in to a PDF using the Drawloop Package and Sent as an email attachment to the recipient. We need to now include the Esignature functionality so that the receipient can view the attachment and sign them. I am not sure if it is best to use Adobe sign/ Docusign/ if there is anything else that comes out of box with the Nintex.

Also is there any samples for adding the signing component in to the PDF that gets generated
