How can I make it so that when I do a mailing list, the mailing list message is sent to all the people who have ever written to the group?

Question

API

Just no idea how to organize it. I hope for your help.

Answer 1

const { VK, createCollectIterator, getRandomId } = require(`vk-io`);

const vk = new VK({
  token: "",
});

(async function () {
  const iterator = createCollectIterator({
    api: vk.api,
    method: "messages.getConversations",
    params: {},
    countPerRequest: 200,
  });

  for await (const chunk of iterator) {
    for (let element of chunk.items) {
      if (element.conversation.peer.type === `user`) {
        // Send message
        /*
        vk.api.messages.send({
          message: "Test",
          peer_id: element.conversation.peer.id,
          random_id: getRandomId(),
                });
                */
      }
    }
  }
})();

To get a list of all the people who have ever written to a group, you can use the messages.getConversations method.
After that, we filter it to get only people, since this method also returns conversations created by the group, and send the newsletter to these accounts in a commented block.
