How to get posts by taxonomy term slug

Hi,

How can I fetch posts using the custom taxonomy term slug in the api call?

I have this in the json

pure_taxonomies: {
location: [
{
term_id: 44,
name: “Birmingham”,
slug: “birmingham”,
term_group: 0,
term_taxonomy_id: 44,
taxonomy: “location”,
description: “”,
parent: 29,
count: 1,
filter: “raw”
}
]
}

I am trying with the following url ( movie is the custom post type)

mywebsite/wp-json/wp/v2/movie?pure_taxonomies.location.slug=birmingham

but it is not returning targeted posts, instead it fetches all posts.

Any help will be appreciated

Thanks
