Login to DropboxSign, and you can cancel from there. If you're the sender and logged into your Dropbox account, you may be able to cancel the signature request from within the platform. Here’s a general guide on how you can cancel a signature request:
Log In: Sign in to your DropboxSign account using your credentials.
Locate the signature request: Find the specific request you want to cancel. It should be listed in your dashboard or under your sent items.
Cancel the Request: Within the details or options for that signature request, there might be a "Cancel" or "Delete" button. Click on it to cancel the request.
Please note that the ability to cancel the signature request might depend on the status of the document and the actions taken by the recipients. If the recipients have already signed the document, it might not be possible to cancel it.
