The user accesses the following route: www.example.com/api/users/x, where x is variable.
How to get x and create routes with dynamic responses?
Automatically translated.
In your router.ex you need to write something like following -
get "/api/users/:x", SomeController, :actionName
Now in your controller, you need to use patten matching to get the value of x from _params, ie:
def actionName(conn, %{"x" => x}) do
# now x is available here
end
