PostProxy is Stripe for social media posting

What Stripe actually solved

Before Stripe, accepting payments online was a nightmare.

You needed to negotiate directly with payment processors. Implement different SDKs for different card networks. Handle PCI compliance yourself. Manage webhooks and retry logic for failed transactions. Build your own idempotency layer. Integrate with dozens of banks across dozens of countries with dozens of different rules.

Stripe did not invent online payments. It made payments something developers could add to an application in an afternoon. A few lines of code, one API key, and suddenly you could charge cards, manage subscriptions, issue refunds, and handle disputes — without knowing anything about the underlying infrastructure.

That abstraction changed everything. Entire companies were built on top of it. Features that previously required months of compliance work became weekend projects. Payments stopped being a reason not to build something.

Social media publishing is in the same place payments were before Stripe.

The current state of social media APIs

Every platform has its own API. Every platform has its own OAuth flow. Every platform has its own quirks.

Want to post to Instagram? You need a Facebook Developer account, a Facebook App, a Business Manager, a linked Instagram Business account, a long-lived token refresh flow, and a working knowledge of which Graph API version currently supports which endpoint.

Want to post to TikTok? Different OAuth spec. Different token format. Different media upload flow. Different content policy rules baked into which API calls succeed or fail.

LinkedIn, X, Threads, Pinterest, YouTube — each one is its own integration project. Each one takes weeks to get right. Each one needs ongoing maintenance as the platforms update their APIs, change their rate limits, deprecate endpoints, or shift their approval requirements.

If you are building an application that needs to publish to more than one platform, you are not building a product — you are maintaining a collection of integrations. That is not what you signed up for.

PostProxy as the abstraction layer

PostProxy does for social media publishing what Stripe did for payments: it hides the complexity behind a clean, unified API.

One API key. One endpoint. One request format. Post to Instagram, LinkedIn, X, Threads, TikTok, YouTube, Facebook, and Pinterest without touching a single platform-specific SDK.

curl -X POST "https://api.postproxy.dev/api/posts" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "post": { "body": "Launching today." },
    "profiles": ["instagram", "linkedin"],
    "media": ["https://your-cdn.com/image.jpg"]
  }'

That is it. PostProxy handles the rest.

OAuth token management. Media upload and transcoding. Platform-specific content formatting. Rate limit handling. Retry logic for transient failures. Status tracking and webhooks. All of it, abstracted away.

What this unlocks

When payments became a simple API call, a new category of products became possible. Subscription businesses that would have taken months to build now take days. Marketplaces that previously required enterprise payment deals are now built by indie developers.

The same thing happens when publishing becomes a simple API call.

AI agents can publish content as a native action, not a separate workflow. Content management systems can push articles to every social platform on publish. E-commerce platforms can announce new products automatically. Marketing automation tools can trigger posts based on events without integrating with five different social APIs.

Features that previously required months of integration work become weekend projects. Publishing stops being a reason not to build something.

The Stripe parallel holds in the other direction too

Stripe is trusted with financial infrastructure. That trust comes from reliability, compliance, and the fact that failures have real consequences — a failed payment is a lost sale.

PostProxy takes the same approach to publishing infrastructure. Idempotency keys prevent duplicate posts when retries happen. Webhook delivery is reliable. Status tracking lets you know exactly what happened to every post. The API behaves predictably even when the underlying platforms do not.

You do not want your publishing layer to be the thing that posts your content twice, or silently drops a post because an upstream API returned a 503. That is the kind of infrastructure problem PostProxy exists to solve.

Building on infrastructure, not around it

The best developer tools are the ones you stop thinking about.

You do not think about Stripe’s internals when you add a checkout flow. You trust that the payment will go through, that the webhook will fire, that the receipt will send. Stripe becomes invisible infrastructure that your product sits on top of.

PostProxy is built to be the same kind of invisible infrastructure for publishing. You make the API call. The post goes out. The webhook confirms it. You never have to think about which version of the TikTok API is current, or whether your Instagram token needs refreshing, or how LinkedIn formats its media attachments.

Publishing is infrastructure. It should feel like infrastructure — reliable, boring, and completely out of your way.
