OnlyFans Integration in a Week: Architecture and Checklist

Ship a production‑ready OnlyFans integration in seven days with a clear architecture, accurate API calls, and copy‑paste checklists. This format is optimized for execution, not theory.

TL;DR

• Use OFAuth Link (hosted) to connect accounts and receive connectionId.
• Call OFAuth Access API with apikey + x-connection-id for stable, signed requests.
• Add retries with backoff, idempotency, and circuit breakers before launch.
• Track login conversion, API errors (400/401/403), and time‑to‑data.

Architecture at a Glance

• Frontend app (connect UI, dashboards)
• Backend API/service (stores users, orgs, connectionId)
• OFAuth Link (hosted auth flow)
• OFAuth Access API (managed + proxy endpoints)
• Optional: Webhooks for lifecycle updates
• Datastore (Postgres/SQLite/D1) + job queue (BullMQ/Cloudflare Queues/Sidekiq)

Day 1 — Foundations

• Create OFAuth account and retrieve OFAUTH_API_KEY (server‑side only)
• Set environment files for dev/staging/prod
• Model org/user entities; add field for connectionId
• Define data you need (profiles, messages, posts, stats)
• Plan hosted Link redirect allowlists for redirectUrl in your client app settings
• Define observability basics (logs, metrics, tracing)

Day 2 — Connect Accounts (Link Hosted)

• Build server endpoint to initialize hosted Link sessions
• Call POST https://api.ofauth.com/v2/link/init with JSON body:

{
	"clientAppId": "app_your_client_app_id",
	"redirectUrl": "https://yourapp.com/connect/callback",
	"clientReferenceId": "user_or_org_id"
}

• Redirect users to the returned url (or open in popup/iframe)
• On success, extract connection from success URL and persist
• Optional: Poll GET https://api.ofauth.com/v2/link/{clientSecret} to confirm status: active
• Render clear states (Connecting, Success, Canceled, Failed)

Example cURL (init hosted session):

curl -X POST https://api.ofauth.com/v2/link/init 
  -H 'content-type: application/json' 
  -H "apikey: $OFAUTH_API_KEY" 
  -d '{
    "clientAppId": "app_your_client_app_id",
    "redirectUrl": "https://yourapp.com/connect/callback",
    "clientReferenceId": "user_123"
  }'

Day 3 — Access API (Data + Actions)

• Implement service wrapper for Access managed endpoints
• Fetch the authenticated user profile:

curl -H "apikey: YOUR_API_KEY" 
     -H "x-connection-id: CONNECTION_ID" 
     https://api.ofauth.com/v2/access/self/me

• Use proxy for long‑tail endpoints while keeping session/signing centralized:

curl -H "apikey: YOUR_API_KEY" 
     -H "x-connection-id: CONNECTION_ID" 
     https://api.ofauth.com/v2/access/proxy/users/me

• Normalize responses and map to internal models
• Handle 400/401/403 with retries and user‑friendly messaging

Day 4 — Data Model, Backfills, and Caching

• Create tables for creators, posts, messages, subscribers, stats
• Background jobs to backfill initial data after connect
• Idempotent job keys; store cursors for pagination
• Introduce caches and TTLs for hot paths (profile, basic stats)
• Precompute aggregates for dashboards (7/30/90‑day windows)

Day 5 — Product Surfaces

• “Connect OnlyFans Account” screen (hosted, later embed)
• Reconnect flow when sessions expire
• Creator dashboard (KPIs, recent posts, messages)
• Messaging workflows within platform limits
• Content scheduler (drafts, queue, preview, publish)

Day 6 — Reliability and Observability

• Retries with exponential backoff + jitter; cap attempts
• Idempotency on writes (messages, uploads)
• Circuit breakers with graceful degradation
• Metrics: login conversion, API latency/error rates, queue depth
• Alerts: spikes of 400/401/403 and “Please refresh the page” errors
• Logs with correlation IDs (per request/job)

Day 7 — Launch & Hardening

• Security review: keys server‑side only; strict redirect allowlists
• Privacy review: limit PII access; audit sensitive reads
• Load test critical flows (connect, fetch, message, publish)
• Feature flags for risky areas; kill switches
• Rollout plan: staged enablement, observability dashboard ready
• Incident playbook: on‑call steps for 400/401/403 clusters

Go‑Live Checklist (Copy/Paste)

Security

• OFAUTH_API_KEY stored in server secrets only
• Success/return URLs allowlisted and validated
• No credentials stored; only connectionId

Reliability

• Retries with backoff + jitter implemented
• Idempotency keys for write operations
• Circuit breakers configured and tested

Observability

• Dashboards for connect success, error rates, queue depth
• Alerts for 400/401/403 spikes and latency SLOs
• Structured logs with correlation IDs

Product

• Connect/reconnect flows tested on desktop and mobile
• Dashboard, messaging, and scheduler flows usable end‑to‑end
• UX copies for errors and recovery paths

Notes

• Default to Access API for speed and stability; use proxy for gaps
• Consider direct calls only when necessary; isolate behind feature flags
• Monitor for “Please refresh the page” and 401/403 as rule‑change signals
