Postproxy is a unified API for publishing to social media platforms. It replaces individual platform integrations and handles platform-specific failures at publish time with one stable publishing layer.

Postproxy is a unified API that enables developers and businesses to publish content, manage comments, conversations, and insights across multiple social media platforms through a single integration. It is designed for developers, SaaS companies, agencies, and marketers who need to embed social features, automate workflows, or manage multiple client accounts efficiently, eliminating the complexity of dealing with each platform's unique API.

Managing social media across different platforms traditionally requires integrating with each platform's separate API, which involves handling varying authentication methods, content formats, rate limits, and failure modes. This process is time-consuming, error-prone, and difficult to scale, especially when managing multiple brands or clients. Postproxy solves this by providing a single, stable layer that abstracts away these complexities, ensuring reliable delivery and clear visibility into publishing outcomes.

A key feature is the unified API and SDKs, which allow sending a single payload to publish across multiple platforms like Instagram, Twitter, LinkedIn, TikTok, and more. Official SDKs are available for popular languages including Node, Python, Ruby, Go, Java, .NET, and PHP, enabling integration in minutes rather than weeks. The API automatically transforms content to match each platform's specific requirements, handles OAuth flows, token storage, and automatic refresh, and manages authentication seamlessly.

Another major capability is full engagement management via API, allowing users to reply to comments, respond to DMs, and manage reviews across all connected platforms through one interface. This centralizes the entire social workflow, keeping interactions connected to the original content. The system also provides webhooks to notify users when posts are published, fail, or are retried, and when comments or DMs need attention, enabling the building of dashboards or triggering of workflows.

For reliability, Postproxy offers delivery guarantees with automatic retries, rate limit handling, quota awareness, and clear per-platform publish state reporting. Every attempt is logged with timestamps and platform-specific outcomes, so users always know what happened. If a post fails, the reason and suggested next steps are visible, ensuring transparency and control over the publishing process.

The product works by acting as an intermediary layer between the user and social platforms. Users send one request with their content and target platforms; Postproxy then maps the payload to each platform's rules, handles format conversion, authentication, and delivery, and returns explicit per-platform outcomes. This deterministic approach ensures that failures are caught early and retries are managed automatically, providing a stable publishing surface despite platform-specific instabilities.
