Posta — Social Media Content & Scheduling

Posta is a social media management platform that lets you create, schedule, and publish posts across Instagram, TikTok, Facebook, X/Twitter, LinkedIn, YouTube, Pinterest, Threads, and Bluesky.

This skill enables you to interact with the Posta API to manage social media content end-to-end: authenticate, list accounts, upload media, create/schedule/publish posts, generate AI content, and view analytics.

Setup

Authentication (one of the following)

• POSTA_API_TOKEN — Recommended. Personal API token (starts with posta_). Long-lived, revocable, no password exposure.
• POSTA_EMAIL + POSTA_PASSWORD — Legacy login. The skill logs in and caches a JWT automatically.

If POSTA_API_TOKEN is set, email/password are not needed and the login flow is skipped entirely.
