Is it possible to send a POST request to api.direct.yandex from a client?

Question

JavaScript

Actually, here is the description api.yandex.ru/direct/doc/concepts/JSON.xml , but is it possible to send a request from the client, without using the backend?

I do something like

var data = {
        "method": "GetClientInfo",
        "param": ["правильный_юзер"],
        "locale": "ru",
        "token": "правильный_токен"
      };
      $.ajax({
        type: "POST",
        url: "https://api.direct.yandex.ru/v4/json/",
        dataType: "jsonp",
        crossDomain: true,
        data: data
      });

But in the end I get the wrong answer. Tell me, in which direction to think, and is such an option possible?

When using the server and sending a request from it, everything works fine.

Answer 1

most likely an API error like XMLHttpRequest cannot load https://api.direct.yandex.ru/v4/json/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'domain' is therefore not allowed access.

Well, here's your answer. Actually what I started with: the browser is blocking a cross-domain ajax request. In short: I don’t think it will be possible to force Yandex to give the desired header (Access-Control-Allow-Origin). Conclusion: no, it will not be possible to make an ajax request to the Yandex api from another domain.

Answer 2

Try Postman . Perhaps Yandex does not support Cross Site Authentication. I didn’t go into details, but you probably specified the domain for your application and thus tied to the api. Therefore, requests are only possible from that domain.
