# Create a comment or reply POST https://services.leadconnectorhq.com/social-media-posting/comments/{platform} Create a top-level comment on a post (`isParentThread: true`, `parentId` = postId) or a reply to an existing comment (`isParentThread: false`, `parentId` = commentId). Per-platform content max length: Facebook 8000, Instagram 2200, Linkedin 3000, Community 8000, Tiktok 150, Bluesky 300, Youtube 10000, Threads 500. **Optional-field platform support:** - `attachments` — supported on **Facebook only**. Ignored on Instagram, LinkedIn, TikTok, Bluesky, Community (Community processes the field but external URLs are not rendered due to its bucket restriction). - `mentions` — supported on **Facebook**, **LinkedIn**, and **Community** only. Ignored on Instagram, TikTok, Bluesky. - `notifyAllGroupMembers` — supported on **Community** only. When `true`, all group members get a push/in-app notification (equivalent to an `@everyone` broadcast). Independent of the `mentions` array and of `@everyone` text in `content`. Default `false`. ## Authentication Send `Authorization: Bearer ` using: - **Sub-Account token: OAuth access token or Private Integration Token.** Scopes: `socialplanner/comments.write` ## Parameters ### Header Parameters | Name | Type | Required | Description | |------|------|----------|-------------| | `Version` | string | Yes | API Version | ### Path Parameters | Name | Type | Required | Description | |------|------|----------|-------------| | `platform` | string | Yes | Supported Comments Platforms | ### Query Parameters | Name | Type | Required | Description | |------|------|----------|-------------| | `locationId` | string | Yes | Location ID | ## OpenAPI Specification ```json { "openapi": "3.0.0", "info": { "title": "LeadConnector API", "version": "v3" }, "servers": [ { "url": "https://services.leadconnectorhq.com" } ], "paths": { "/social-media-posting/comments/{platform}": { "post": { "summary": "Create a comment or reply", "operationId": "createACommentOrReply", "description": "Create a top-level comment on a post (`isParentThread: true`, `parentId` = postId) or a reply to an existing comment (`isParentThread: false`, `parentId` = commentId).
