Why Use the DMs API

How Much Does a Social Media DM API Cost?

Building a unified messaging layer across 10 platforms means dealing with Meta's Graph API, Telegram's Bot API, X's DM endpoints, TikTok's Business Messaging API, Slack's Events API, and more, each with different auth, formats, and rate limits. Here's how Zernio compares.

* Zernio bundles DMs, comments, and review management with every connected account. Comments and reviews are unmetered; sending DMs is free to 10,000 a month, then $1 per 10,000.

Code Examples

const res = await fetch(
  "https://zernio.com/api/v1/inbox/conversations?accountId=ACC_ID",
  { headers: { Authorization: "Bearer YOUR_API_KEY" } }
);
const { data, pagination } = await res.json();

await fetch(
  "https://zernio.com/api/v1/inbox/conversations/CONV_ID/messages",
  {
    method: "POST",
    headers: {
      Authorization: "Bearer YOUR_API_KEY",
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      accountId: "ACC_ID",
      message: "Hey! How can I help you today?"
    })
  }
);
