If this is a specifically a ZOOM meeting, then without getting into the nitty-gritties of programming an API, try ZAPIER. Zapier is a tool that "sits" between two APIs and allows you to exchange data. In this way you can for example tell Zapier where the Wordpress data is in a specific account and which zoom meeting you want to add the new attendee to and define the data that needs to be transferred.
Otherwise a quick and dirty trick is to define the meeting as a webinar, import the attendee list and then change the webinar to a meeting. You can only make this change once AND only in one direction....no going back.
