i am new to v2, i use v1 for long time, currently upgrade to v2, i try to get all the terms belong to specific custom taxonomy.
In v1 i can do this to get terms /taxonom
Taxonomy terms are simply called this way:
https://yoursite.com/wp-json/wp/v2/the-taxonomy-slug
For instance, to answer your question:
https://yoursite.com/wp-json/wp/v2/location_category
From terminal:
curl -X GET -i http://www.example.com/wp-json/wp/v2/location_category
