I'm wondering if it is possible to create a frontend submission form using Metabox form builder for a 3rd party plugin. I've created a custom post type for "Meetings" and have a form set up for that fillable from the frontend. One of the fields is for the shortcode to use for a Zoom meeting that is associated with the Meeting. Not all Meetings will have a Zoom component. Right now the Zoom plugin requires creating the Zoom meeting in the admin side of the site. I would like to have users do that on the frontend as it is a private site and I don't want them in the admin area. Can this be done? Would it be possible to combine my CPT frontend form with the Zoom frontend form if it is possible?
