URL Redirect After Signing add-on
WP E-Signature's URL Redirect After Signing add-on allows you to automatically redirect your signer to a fixed URL after they successfully sign a document.
To get started, visit E-Signature > Add-ons > find URL Redirect After Signing Add-on > Enable.
Then create a new document or open an existing document in editing mode and view the URL Redirect option on the top right of the page.
Type or paste in the URL you'd like your signers to arrive at after they sign your document > Add > publish your document.
Then test by signing and getting redirected to your desired page.
