How to Auto-DM New Twitter (X) Followers With an API

To auto-DM new X (Twitter) followers, you poll your followers on a schedule, diff the list against the followers you have already seen, filter the new ones to accounts that can receive a DM, and send each a paced, personalized welcome message. This guide shows the detection loop in code and how to send safely.

Done right, this turns every new follower into a warm conversation. Done wrong, it is the fastest way to get an account flagged. The difference is filtering, personalization, and pacing.

The workflow

1. Poll your followers on an interval.
2. Diff against a stored set of followers you already know, to find new ones.
3. Filter the new ones to DM-able accounts that fit your customer profile.
4. Send each a personalized welcome DM, paced and one message variant at a time.

Detect new followers (Node.js)

Scraping followers is a single request, and the seen-set diff finds the new ones:

const known = new Set(); // persist across runs (DB / KV)

async function findNewFollowers() {
  const res = await fetch("https://app.xautodm.com/api/v1/scrapes", {
    method: "POST",
    headers: {
      "Authorization": "Bearer xad_live_...",
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      source_type: "followers",
      source_value: "https://x.com/yourhandle",
      count: 500,
      filters: { canDmOnly: true },
    }),
  });
  const { data } = await res.json();

  const fresh = data.filter((f) => !known.has(f.username));
  fresh.forEach((f) => known.add(f.username));
  return fresh; // new, DM-able followers only
}

Two details matter.

Send the welcome DM

Sending is the other half of the XAutoDM API, under the same key. Request the DM endpoint reference with your early-access key on the API page, then send one personalized message per new follower:

for (const f of fresh) {
  await sendDm({
    to: f.username,
    text: `Hey ${f.name.split(" ")[0]}, thanks for the follow. What are you working on right now?`,
  });
  await sleep(jitter(60, 180)); // space sends out, seconds
}

Note the pacing. A short delay with jitter between sends keeps you under X's DM limits and away from the spam filter. Never send identical text at volume; personalize with the follower's name or bio and rotate a few variants.

Keep it safe

• Filter before you send: DM-able only, skip your do-not-contact list, skip poor-fit accounts.
• Personalize every message: name or bio detail, no copy-paste.
• No links in the first message: earn the reply first.
• Pace and warm up: space sends across the day; ramp new accounts slowly.

Let the platform run it

You can wire this yourself, or let the managed side of XAutoDM handle the loop: it detects new followers, filters them, and sends paced, personalized DMs with follow-ups that stop on a reply, tracking each to a booked call. Either way, start with the data: see how to scrape X data with an API and request a key on the API page.
