UniPost

UniPost is a unified social publishing API for developers who need to post across multiple social platforms from one integration. It is built for apps, workflows, agents, and SaaS products, and it is described as a way to stop maintaining separate social media integrations.

The service is organized around account connection, media upload, publishing, and delivery tracking. It says it turns platform differences such as connection models, content constraints, media behavior, publish lifecycles, and failure modes into one API. Supported actions include onboarding accounts, publishing posts, scheduling or drafting content, reporting analytics, receiving delivery events through webhooks, managing API keys, and handling inbox workflows. The documentation also says a publish request can include text, media, or per-platform variants, and that UniPost handles validation and delivery behind the single request.

Delivery is through an API and hosted OAuth flows. The production path is presented as three steps: get an API key, connect customer accounts, then send publish requests through the API. The page names endpoints for connect sessions, posts, analytics, webhooks, API keys, and inbox access, and it shows account IDs being used in a publish call. It also lists the social platforms X, LinkedIn, Instagram, TikTok, Threads, YouTube, Facebook, Pinterest, and Bluesky, while the headline says it can publish to every social platform with one API.

The site footer links to a Pricing page, but no plan details appear in the text provided. UniPost is presented as a developer-focused API product rather than a consumer app.
