Configure eSignature REST API for Wordpress Site

Client is currently using WPEsignature with Contact Form 7 on their Wordpress site to have users request a Rental Agreement be sent to their inbox for signature. Client wants to get off these two plugins and switch to Docusign for security, speed, and ease of use. Within Docusign, the Rental Agreement Template envelope is configured. We need assistance getting the eSignature REST API set up with the client site, so users can request the document and sign it from a form on the website, or have the document sent to their email. https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/embedding/embedded-signing/ This is above our team's expertise, so anyone with Wordpress + Docusign + JS development skills is needed.
