The Problem

Building OnlyFans integrations is hard:
  • Reverse engineering: OnlyFans has no public API. You need to reverse engineer request signing, session management, and authentication flows.
  • Constant changes: OnlyFans changes their API frequently—sometimes multiple times per day. Every change breaks your integration.
  • Security liability: Storing OnlyFans credentials creates security and compliance risks for your platform.
  • Maintenance burden: Keeping integrations working requires dedicated engineering resources.

Real example: A typical OnlyFans integration requires reverse engineering request signing, building session management, handling 2FA flows, and monitoring for API changes. Teams report spending 3-6 months just to get basic functionality working.

​
Platform-First Architecture

OFAuth is designed for multi-tenant platforms managing many OnlyFans accounts—not just single-account tools.

Connection Management

Each connected account gets a unique Connection ID. Manage hundreds or thousands of connections through a single API.

Per-Connection Billing

Pay only for active connections. Expired sessions don’t count toward your usage.

Webhooks at Scale

Get notified when connections expire, sessions refresh, or accounts need re-authentication.

Enterprise Features

Whitelabel options, dedicated support, and custom SLAs for high-volume platforms.

​
Security Model

OFAuth uses a delegated authentication model similar to Plaid or OAuth providers:
1

User authenticates on OFAuth

Users enter credentials on our secure, hosted authentication page—never on your servers.
2

OFAuth manages sessions

We handle session storage, refresh, and encryption. Credentials never touch your infrastructure.
3

You use Connection IDs

Your platform only stores a simple Connection ID string. No sensitive data to protect.
Compliance benefit: Since credentials never touch your servers, you reduce PCI-style compliance scope and security audit complexity.

​
Always Up-to-Date

OnlyFans changes their API frequently. OFAuth’s Dynamic Rules Engine handles this automatically:
  • 24/7 monitoring detects API changes within minutes
  • Automatic updates to request signing parameters
  • Zero downtime for your integration
  • Webhook notifications for breaking changes that affect your integration
Without automatic updates, a single OnlyFans API change can break your entire integration until you manually reverse engineer and deploy fixes—often taking days.

​
Full TypeScript SDK

Unlike raw REST APIs, OFAuth provides a full TypeScript SDK: 
import OFSDK from "@ofauth/onlyfans-sdk"

const sdk = new OFSDK({
  mode: "access",
  ofauthApiKey: process.env.OFAUTH_API_KEY
})

// Type-safe, with IntelliSense
const { data, error } = await sdk.messages.sendChatMessage({
  authentication: { connectionId: "conn_123" },
  userId: 456,
  params: { text: "Hello!" }
})
