Postproxy
Postproxy · Marketing · Other
Postproxy is a unified social media API that handles publishing, comments, direct messages, and insights across many platforms through one integration. Instead of wiring up Instagram, TikTok, LinkedIn, X, YouTube, Facebook, Threads, and Bluesky separately, you send one payload and let Postproxy map it to each platform's rules. Why bother? Because maintaining eight integrations is a job on its own. It's built for agencies, SaaS products, and AI agents that publish on behalf of other people.
About Postproxy
What Is Postproxy
Postproxy is an API service, not a dashboard you click through. The selling point is simple. One integration layer for the whole social workflow. You authenticate once, connect profiles, then publish, reply to comments, answer DMs, and pull insights from a single contract. The service absorbs the messy parts of working with many platforms, like per-platform formatting rules and partial failures, so your code doesn't have to branch for every network.
The people who get the most out of it are developers building social features into their own products. A SaaS tool that lets customers schedule posts, or an agency running dozens of client accounts, would otherwise maintain a handful of separate integrations and never stop paying that maintenance tax. Postproxy collapses that into one set of endpoints, with official SDKs for Node, Python, and Ruby to cut the setup time.
The main limitation is reach into the social platforms themselves. When a network caps how often you can post, that ceiling still applies. X, for example, is limited to 20 posts per 24 hours per account on standard plans. Postproxy can't lift a platform's own limits, and higher X throughput needs pay-as-you-go or bring-your-own-key options.
Getting Started
- Sign up at the Postproxy app with just an email; no credit card is needed to start.
- Generate an API key from your account and confirm the free tier covers 10 posts.
- Connect the social profiles you want to manage, following the hosted authorization flow for each platform.
- Send your first request to the publish endpoint with a body, target profiles, and any media URLs.
- Read the per-platform response to confirm each network accepted the post, then build your scheduling and reply logic on top.

Key features
One API for the Whole Workflow
Postproxy replaces separate per-platform integrations with a single interface for publishing, comments, conversations, and insights. You learn one contract instead of eight. That's the core reason teams pick it over building directly against each network.
Single Payload, Multiple Platforms
You send one payload and Postproxy maps it to each platform's rules, then returns a per-platform outcome. If Instagram accepts a post but X rejects it, you see both results clearly. No guessing which network failed. This is where the abstraction earns its keep.
Official SDKs for Fast Integration
The service ships official SDKs for Node, Python, Ruby, and other common languages, alongside plain REST endpoints. The team's pitch is integrating in about 30 minutes rather than weeks. That holds up if you're using a supported language.
Full Engagement Through the API
Beyond publishing, you can reply to comments, respond to DMs, and manage reviews across all connected platforms. That means a support or community workflow can run from the same API key as your posting logic. Fewer systems to keep in sync.
Webhooks, Retries, and Logs
The API includes webhooks for post status, retries, and logs, with per-platform results in one response. For automation you get the visibility you need when something goes wrong. Not glamorous. But it's the difference between a toy and something you'd run in production.
Profile-Group Billing for Teams
SaaS products and agencies pay per connected profile group, where a group usually maps to one brand, client, or publishing setup and can hold up to 11 connected platforms. Agents and automations pay per connected profile instead. Two billing models cover two very different use cases. Pick the one that matches how you ship.
Pros and cons
Pros
- Removes the need to maintain a separate integration for every social platform, saving weeks of engineering that would otherwise go into plumbing rather than product work.
- Per-platform result reporting makes partial failures visible instead of silent.
- Official SDKs for Node, Python, and Ruby lower the setup cost for common stacks.
- Free tier covers 10 posts, so you can test the workflow before paying.
- Engagement features like comments and DMs mean one API handles more than just posting.
Cons
- Platform rate limits still apply; X caps you at 20 posts per 24 hours per account, and higher throughput costs extra.
- It's an API-first product, so non-developers can't use it without writing code.
- Pricing scales with connected profiles or groups, which gets expensive for very large operations.
