Thanks for getting back to me apologies, the fisr URL I send was another post I was looking at, not the API call back the 2nd API call displays the same results. So yes I can see the following in the data:
xs_robots: "noindex, nofollow"
But it’s missing two custom meta boxes which I created in the same file as the majority of the above entries. Here is the file where I create the meta boxes, https://gist.github.com/xanthestudios/02b94880b71dd90ecbb28e5aa5ee63a2. YOu can see that most of them are shoiwng in the API results apart from xs_venue_short, xs_venue_long, xs_dates_start_date, xs_dates_end_date and xs_dates_entry_deadline.
Thank you for your input so far.
