Edit published post

Edit the text of an already-published post. Supported on X (Twitter), Discord, Facebook, and Reddit. Each platform enforces its own rules:

X (Twitter)

• Connected X account must have an active X Premium subscription
• Must be within 1 hour of original publish time
• Maximum 5 edits per tweet (enforced by X)
• Threads cannot be edited, only single tweets
• X assigns a NEW post ID on edit, returned as id

Discord

• No time limit and no premium requirement
• The message ID is unchanged after the edit

Facebook

• Graph only permits editing a post that the same app created, so this works on posts published through Zernio and is rejected for posts created in Meta Business Suite / Composer or by another tool
• Media cannot be swapped, only the message text
• Reactions, comments, and shares are preserved. The post ID is unchanged

Reddit

• Self-posts only. A link post has no editable body and is rejected before the write
• Body only. Reddit exposes no API to edit a post title, ever
• The post ID is unchanged

Media edits are not supported on any platform. The post record in Zernio is updated with the new content and an edit-history entry.

import Zernio from '@zernio/node';const zernio = new Zernio({ apiKey: process.env.ZERNIO_API_KEY });const { data } = await zernio.posts.editPost({  path: {    postId: 'post_abc123',  },  body: {    platform: 'twitter',    content: 'Hello, world!',  },});console.log(data);
