Rest api call inside application

Hey Karthik, Is the document that's being signed a standard document where only the data in the fields changes? Or is it a unique document for each case? If it's a unique document each time, you could use one of our extraction methods to place the fields dynamically in the document: Text Tags Document Extraction (PDF Form Fields) If it's a standard document that won't change except the user entered info and signatures, you could use one of the above extraction methods or you could much more easily just use XY coordinates as you'll find in the Quick Start Guide or you could create a Template in the UI (or via the API) and simply use that as the basis for the transaction, each time. If you're using forms in the application to pre-fill the document, you'll need to update the field values before sending the transaction. With the XY coordinate method, you can pass the values through the payload. With the Text Tag method, you could potentially modify the document tags to add the entered values to be extracted by eSignLive. Otherwise, you'll need to do update document calls to update the field values before you send the transaction. If you'll use eSignLIve's signing ceremony to collect the information, you won't need to worry about any of this part. To embed the signing ceremony in your website, you'll simply need to get a signerAuthenticationToken after sending the transaction and make the src of your iframe: https://sandbox.esignlive.com/access?signerAuthenticationToken={token} Hope this helps. Let me know if you have questions.
