Post Creation Example

{
  "date": "2024-12-01",
  "time": "10:00",
  "timezone": "America/New_York",
  "schedule": true,
  "accounts": [1, 2, 3],  // Account IDs are integers, not UUIDs
  "tags": ["tag-uuid-1"],
  "versions": [
    {
      "account_id": 1,  // Account ID must be an integer
      "is_original": true,
      "content": {
        "body": "Hello, world! This is my social media post.",
        "media": [],
        "urls": ["https://example.com"]
      },
      "options": {}
    }
  ]
}

Important Notes:

• Account IDs in the accounts array and account_id fields must be integers, not UUIDs
• Use the mixpost_list_accounts tool to get the numeric IDs for your accounts
• Content should be formatted with HTML tags (e.g., <div> for line breaks)
• For draft posts, use schedule: false and queue: false
• The content structure for versions is an array of objects, not a single object
