Is there a way for a user to fill out a Gravity Form and then take that info to fill the PDF? Afterwards they will simply sign the filled out PDF.
Thank you for your interest in GroupDocs. From your request it looks like you are interested in our WordPress Signature plugin. Have you investigated it's functionality already? If you have perhaps you have a few questions that I can help you with?
If you need some additional functionality in our Signature plugin for WordPress - that is also possible, however we'd need a paid subscription on your part to proceed with modification, ideally a Premium API subscription or above.
Please let me know if you have any other questions and I'll be glad to help?
