Do we need to update code on website  if we made any changes on jotform?

If you have downloaded and used the source code, then you should re-embed your source code on website when you update it. For other publish methods (such as embed, iframe, pop-up), it is not neccessary to re-embed.

For further information about publishing methods, please check this guide; https://www.jotform.com/help/67-Which-Form-Embed-Code-Should-I-Use

Hope this helps. Thank you.

Deniz is right. You do not need to update the code if you are using the default embed code, iframe, lightbox or popup. However, this is not the case for the full source code. You will have to update them manually whenever you made changes to your form.
