With Gravity Forms, when a form is submitted it will be saved in DB and sent as a notification (with some field entries from the form) to a number of email addresses. I would like the recipient of the email to respond to the email via a URL or a second form.
Their response from the email notification should be recorded on the form entry sent to them first time on the DB. Is a URL or a second form better to do this? How can I best achieve this? I understand I could use the ID associated with each Gravity Forms form entries.
But not sure how I can reference the ID so that their response is recorded on the form entry.
A URL could redirect the recipient to a form which prompts their response. But not sure how to reference the original form entry and record their response on the original form entry?
Would one need develop a listener to the response so that once it is received we do a insert or update DB action?
