QUICKSTART CODE / MCP CONFIGURATION

    "profileId": "prof_default_01",

    "autoAdjustMedia": true

1. Unified Meta v21.0 OAuth Across Instagram, Facebook Pages & Threads

Nuntior integrates dedicated OAuth flows for Instagram Business (/v1/oauth/instagram/start), Facebook Pages (/v1/oauth/facebook/start), and Threads (/v1/oauth/threads/start). Tokens are automatically exchanged for long-lived 60-day credentials and stored in Nuntior’s AES-256-GCM encrypted vault.

2. Automatic 9:16 Aspect-Ratio & Audio Normalization

Set autoAdjustMedia: true on social_publish or POST /v1/posts to normalize 9:16 vertical video dimensions (1080x1920) and loudness (-14 LUFS) across Instagram Reels, TikTok, and YouTube Shorts.
