Why Use the DMs API

How Much Does a Social Media DM API Cost?

Building a unified messaging layer across 7 platforms means dealing with Meta's Graph API, Telegram's Bot API, X's DM endpoints, and more — each with different auth, formats, and rate limits. Here's how Zernio compares.

* Zernio's Inbox add-on bundles DMs, comments, and review management together.

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?"
    })
  }
);

{
  "event": "message.received",
  "data": {
    "messageId": "msg_abc123",
    "conversationId": "conv_456",
    "platform": "instagram",
