How to accept a response from liqpay?

Question

Yii

Good day! Created a company on liqpay. In the API settings in the "URL of the store client-server:" I entered the address of the site where this data should simply be displayed via print_r (). In the Checkout/API section, I checked the autoredirect and post date checkboxes. I create a test button and put the form on the site. After the transition, I fill out the form and click the "Pay" button. Then the redirect is triggered and the browser tells me that I am trying to transfer data over an insecure channel, and when I click "Continue" I am redirected to the site but there is a Bad Request (# 400). Tell me what's the problem? As far as I understand this is a problem in _csrf but I don't know what to do. Can you please tell me what to do in this situation?
Thanks in advance!

Answer 1

Bad Request (#400) - as I understand it, yii2 issues. Then the problem is in _csrf. Solutions 2:
1. pass _csrf with the form
2. disable validation in the action that the request is knocking on or in the entire controller, like this:

public function beforeAction($action)
  {
    $this->enableCsrfValidation = false;
    return parent :: beforeAction($action);
  }
