How to fetch message views using TaaS

views.js

async function taasRequest(data) {
  data.api_key = "xxxxxx:xxxxxxxx";
  let res = await fetch('https://api.t-a-a-s.ru',
        method: 'POST',
        body: JSON.generate(data)
  )
  res = await res.json();
  return res;
}

const channelToScan = "profunctor_io";

let res;

// First we get chat_id from username
res = taasRequest({
  "@type": "searchPublicChat",
  "username": channelToScan
})

const chatId = res.chat_id; 

// Then we get necessary messages
res = taasRequest({
  "@type": "getChatHistory",
  "chat_id": chatId,
  "limit": "100",
  "offset": "0",
  "from_message_id": "0"
})

const messageIds = res.messages.map(m => m.id);

// View messages is necessary for view counter to update, otherwise it's stalled
taasRequest({
  "@type": "viewMessages",
  "chat_id": chatId,
  "message_ids": messageIds
})

res = taasRequest({
  "@type": "getMessages",
  "chat_id": chatId,
  "message_ids": messageIds
})

// Finally print views counts
res.forEach(message => console.log(message.interaction_info.views_count))
