Can we merge the form submission with wordpress user registration field?

can we merge the form submission with wordpress user registration fields? Say we if someone register with this form will create user login for wordpress

Unfortunately registration and login forms are not allowed in JotForm, you are not able to add the "password" field to any forms or your account would be breaking our terms of use and would be suspended by our system.

Now if you do not have the need for password to be captured on the field, you could send the responses to the endpoint in your WordPress installation that would help you capture the submitted data and create the user. Unfortunately I do not think that there is any plugin that would allow you to do this, so you would need to create the plugin / change the code yourself in order to do this.

You have to use a webhook to create a user in WordPress, please read this article on how to setup a Webhook with JotForm.
