Hello Matthew,
Thanks for reaching out!
How are you trying to run the search? Are you using the right parameter? In WP the search URL parameter is s but in the REST API (WP and ours) is search.
So, if I want to search https://domain.com, using TEC REST API, to look for all events that container “Foo” in the title or description I will use https://domain.com/wp-json/tribe/events/v1/events?search=foo (case insesitive).
Can you share with me the full URL you are using to fetch results?
Let me know and we’ll figure this one out.
Cheers,
Andras
