Changelog

A record of significant changes to the OnlyFans API Gateway platform.

May 24, 2026

Added
  • WebSockets documentation — New reference page covering the WebSocket relay endpoint, authentication, available actions, all connection error codes, and a reconnection pattern with exponential backoff.
Fixed
  • WebSocket connections dropping after 20 seconds — The gateway was sending an empty JSON frame {} as a keep-alive heartbeat. OnlyFans treated this as an invalid command and responded with an error, closing the connection. The heartbeat now uses a WebSocket protocol-level PING frame, which OnlyFans handles transparently without error.

Added
  • Audit Log — Every significant organization action is now recorded: API key creation, revocation, and rotation; member invitations, role changes, and removals; model connections; subscription events. Accessible from the sidebar (Admin only).
  • API Key Rotation — Rotate an API key secret without revoking and recreating it. The old key is invalidated immediately and the new key is shown once.
  • Model Setup Guide — Step-by-step documentation with screenshots for connecting a model account and making a first request.
  • Troubleshooting Guide — Solutions for all common API errors including 401, 402, 429, 502, session expiry, and signing failures.
  • Cost Calculator — Interactive tool on the Billing page to estimate monthly credit usage based on expected request volume per endpoint.
  • "Try it" buttons — Every endpoint card in the API Reference now links directly to the Playground with that endpoint pre-selected.
  • Changelog — This page.
Improved
  • Admin-only pages now redirect non-admin users to the dashboard instead of showing blank content.
  • Password confirmation required before viewing 2FA recovery codes.
  • Empty states across API Keys, Models, and Logs pages now include contextual action buttons.
  • Playground remembers the last configuration per endpoint across sessions.
  • Table of Contents now visible on screens 1024px and wider (previously 1280px+).
  • API Reference sidebar now shows section sub-links (User, Chats, Stats, Vault, Media, Fans, Payouts) when the page is active.
Fixed
  • "Copy this page" and "Copy full documentation" in the Ask AI dropdown were silently failing in all environments — now fixed.
  • Internal infrastructure details (server IPs, connection pool info) were leaking in signing error responses — now replaced with a generic user-facing message.
