Django Rest Framework, CSRF and Vue.js

So I'm posting this as an answer to close the question.

The issue was because of the wrong CSRF header name that was sent on request. According to documentation:

As with other HTTP headers in request.META, the header name received from the server is normalized by converting all characters to uppercase, replacing any hyphens with underscores, and adding an 'HTTP_' prefix to the name. For example, if your client sends a 'X-XSRF-TOKEN' header, the setting should be 'HTTP_X_XSRF_TOKEN'.

Also I'm leaving here a reference to my question, which accumulates several problems that may lead to CSRF Failed: CSRF token missing or incorrect. error in Django.

Get token from cookie:

function readCookie(name) {    var nameEQ = name + "=";    var ca = document.cookie.split(';');    for(var i=0;i < ca.length;i++) {        var c = ca[i];        while (c.charAt(0)==' ') c = c.substring(1,c.length);        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);    }    return null;}var csrftoken = readCookie('csrftoken');

Send token in headers POST:

  this.$http.post('http://'+document.location.host+'/api//',{params: {foo: 'bar'}}, {headers: {"X-CSRFToken":csrftoken }}).then(function (response) {            this.response = response.data;        },        function (response) {            console.log(response);        });
