for use in testing stripe intents server side. note this is for use with a test mode key. relies on implementation details that might change

simulate_3dsecure_action.js

const { STRIPE_PUBLIC_KEY } = process.env,
  axios = require("axios"),
  qs = require("querystring").stringify,
  { JSDOM } = require("jsdom");

module.exports.simulateAction = async function(
  intentId,
  clientSecret,
  mode = "setup_intent"
) {
  // These are all the bits we have to gather as we go along
  const data = {
    url1: null,
    url2: null,
    url3: null,
    url4: null
  };

  if (mode === "setup_intent") {
    data.url1 = `https://api.stripe.com/v1/setup_intents/${intentId}`;
  } else {
    data.url1 = `https://api.stripe.com/v1/payment_intents/${intentId}`;
  }

  try {
    const res1 = await axios({
      url: data.url1,
      method: "GET",
      params: {
        is_stripe_sdk: false,
        key: STRIPE_PUBLIC_KEY,
        client_secret: clientSecret
      }
    });
    data.url2 = res1.data.next_action.use_stripe_sdk.stripe_js;
    
    const res2 = await axios({
      url: data.url2
    });
    const doc2 = new JSDOM(res2.data);
    data.url3 = doc2.window.document.querySelector(`input[name='return_url']`).value;

    const res3 = await axios({

    });
  } catch (err) {
    console.dir(err);
    throw new Error("simulateAction failed");

};

This broke in late Aug 2021, had to remove a bit of the logic for going from step 3 to 4. should work again
