Feature Comparison
Postproxy
The Unified API Endpoint
This is the whole vibe. One single API call to rule them all. You stop worrying about whether Instagram wants a square video or if LinkedIn has a character limit today. You just send your post, pick your platforms (like ["instagram", "linkedin"]), and attach your media. Postproxy takes that and does all the dirty work of talking to each platform in their own special language, so you don't have to learn five different dialects of API nonsense. It's the ultimate simplification.
Automated OAuth & Token Management
The absolute worst part of any integration? The auth dance. App reviews, permission scopes, tokens that expire at 3 AM—it's a bureaucratic hellscape. Postproxy becomes your auth guardian. You connect your social accounts once, and it handles all the token storage, refresh cycles, and re-authentication silently in the background. You just use your Postproxy API key forever. No more midnight panic because a token died.
Built-in Failure Handling & Retries
Social platform APIs are flaky. Rate limits hit you out of nowhere, quotas mysteriously vanish, and posts fail silently. Postproxy is built expecting this chaos. It automatically handles rate limits with smart backoffs, retries failed publishes, and is fully aware of platform quotas. Most importantly, it gives you explicit, clear statuses on what succeeded, what failed, and why. No more manual detective work.
Content Adaptation & Format Conversion
You can't just blast the same raw text and video everywhere. Instagram needs specific aspect ratios, X has a link card thing, YouTube wants a description. Postproxy acts as your content shape-shifter. It automatically transforms and optimizes your post body, titles, and media to match the requirements and best practices of each destination platform, maximizing your chances of a successful publish without you lifting a finger.

Use Cases
Postproxy
The AI Content Firehose
You've got LLMs or AI agents pumping out brilliant content 24/7, but then the publishing step breaks the whole flow. Postproxy slots right in as the final, reliable delivery layer. Generate your post with AI, send it straight to the Postproxy API, and watch it flow out to all your social channels without you having to manually tweak the format for each one. It turns AI generation into a fully automated publishing pipeline.
Multi-Client/Agency Social Management
Managing posts for a dozen different clients or brand accounts is account sprawl madness. With Postproxy, you connect all those different Facebook Pages, Instagram profiles, and LinkedIn company pages once. Then, from your central dashboard or API, you can publish to any combination of them with a single request, keeping access control and logging clean and centralized. Scaling client work becomes trivial.
n8n/Zapier Automation Workflows
You're building killer automations in n8n or Zapier that trigger on events—like a new blog post, a product update, or a calendar alert. The workflow runs perfectly until the "Publish to Social" step, which requires five different, fragile integrations. Replace that whole tangled mess with one robust Postproxy step. It makes your automations actually reliable from start to finish.
CI/CD for Social Content
For the devs who want to treat content like code. You can store post copy and assets in your repo, and use CI/CD pipelines to schedule and deploy social updates. Postproxy's API fits perfectly into this model, allowing you to trigger publishes via scripts or pipeline jobs. It brings software engineering best practices—version control, rollbacks, and automated deployments—to your social media strategy.

Overview
About Postproxy
Alright, let's cut through the noise. Postproxy is the single API that finally makes social media publishing not a total nightmare. Think of it as the universal translator and bouncer for your content, handling the messy, platform-specific drama so you don't have to. It's built for devs, automators, and anyone who's tired of juggling a dozen different API keys, OAuth flows, and random rate-limit errors from Instagram, Facebook, YouTube, LinkedIn, and X. Instead of writing and maintaining a mountain of custom code for each platform's ever-changing rules, you just send one clean request to Postproxy. It does all the heavy lifting: automates the boring auth stuff, handles rate limits and retries like a champ, magically adapts your content to fit each platform's weird quirks, and gives you clear analytics. It turns the chaotic, unreliable mess of multi-platform posting into predictable, boringly reliable infrastructure. Whether you're building in n8n, Zapier, with LLMs, or in your CI/CD pipeline, Postproxy is the missing piece that makes "set it and forget it" publishing actually possible. Oh, and there's a free plan to get you started. Basically, it's the cheat code for social media automation.

Frequently Asked Questions
Postproxy FAQ
What platforms does Postproxy support?
Right now, Postproxy handles the big players where publishing is most complex: Instagram, Facebook, YouTube, LinkedIn, and X (formerly Twitter). The whole idea is to cover the platforms with the most bureaucratic APIs and weird rules, giving you one smooth interface for all of them.
How does Postproxy handle media like images and videos?
You just provide the public URLs to your media files (like from S3, Cloudinary, etc.) in your API request. Postproxy's backend then downloads, processes, and reformats that media as needed for each specific platform's requirements—things like resizing, transcoding video, or generating thumbnails—before uploading it directly to the social network.
Is my data and access secure with Postproxy?
Totally. Postproxy acts as a secure proxy. Your API key and requests are encrypted in transit. For platform access, it uses official OAuth flows, so you're granting permission directly to Postproxy's secure app. It stores only the necessary tokens (encrypted) to perform actions on your behalf and never stores your social account passwords.
What happens if a platform's API changes or breaks?
This is a core part of Postproxy's value. Their team monitors all the supported platform APIs obsessively. When Instagram or LinkedIn rolls out a breaking change, Postproxy updates its internal adapters so your integration stays stable. You maintain one constant API contract with Postproxy, and they deal with the shifting sands of the social platforms for you.
