How to Publish to Any Social Platform from Inside Your Product with Unified.to

Unified.to’s Social Media API enables products to publish content to customers’ connected social accounts through a single SDK method and standardized Post object, covering platforms such as LinkedIn, Instagram, Bluesky, Google Business Profile, Mastodon, and Pinterest while executing writes directly on the originating platforms. Customers authorize accounts to generate connection IDs, applications list available profiles for account selection, and composers can support text, media, accessibility alt text, titles, calls to action, post types, replies, quotes, language, and scheduling where individual platforms allow them. Because platform capabilities and requirements differ, developers are advised to consult the integration capability matrix, adapt interfaces to supported fields, enforce mandatory media rules for platforms such as Instagram and Pinterest, and interpret 501 responses as unsupported functionality rather than retryable failures. After creating a post, applications should store its returned ID and retrieve its status and public URL to distinguish published, processing, rejected, draft, scheduled, or deleted states. The API also supports listing existing posts and metrics, updating or removing posts where available, replying through parent post IDs, and publishing the same content to multiple profiles through separate calls, while applications may need their own scheduling system when a platform does not support native scheduled publishing.
