The current script is attatched check it !!! Its for “ webook.com “ Website If u r someone who want me to provide all of things and do all of things ?? Dont bid i want someone creative care about dilverables and read my offer well . I have a working Tampermonkey userscript (v10.0) that bypasses the virtual waiting queue on a ticket booking website. The script successfully removes the queue overlay and exposes the "Book Tickets" button. However, once clicked, the page navigates to `/book` and an embedded iframe (seatcloud.com seating chart widget) loads for a split second then **immediately dies** with a "Session Expired" message. I need a developer experienced with browser extensions, Tampermonkey/Greasemonkey scripting, API interception, and session/token management to diagnose and fix this. --- Current Behavior: 1. Script activates on page load = works 2. Queue/waiting line is bypassed successfully = works 3. "Book Tickets" button becomes visible and clickable = works 4. Page navigates to `/event-slug/book` = works 5. Seatcloud iframe loads → instantly closes itself = problem 6. "Session Expired" / "Hold Token Expired" message appears = problem --- My Technical Analysis (Expected Root Cause): In the **normal user flow**, the process works like this: ``` User waits in queue → Queue releases user → Server generates a "hold token" → /book page loads → iframe receives hold token via config → Seating chart works ``` In the **bypassed flow**, the process breaks here: ``` Script skips queue entirely → No server-side hold token is ever generated → /book page loads → iframe has NO valid token → Widget fires "holdTokenExpired" → Session killed instantly ``` **The core problem:** The hold token is issued server-side as a RESULT of completing the queue. By skipping the queue, we skip the token issuance step. The iframe widget validates the token on initialization — finds nothing (or finds a null/stale value) — and self-destructs. **The fix likely involves one of the following approaches:** - Intercepting the booking initialization API call that normally issues the hold token, and triggering it manually/programmatically after queue bypass but BEFORE the iframe renders - Gating/delaying the iframe `src` injection until a valid hold token is captured from the network - Hooking into the WebSocket or API response that carries the hold token and storing it, then injecting it into the iframe config - Possibly replaying or spoofing the queue-completion handshake so the server believes the user exited the queue legitimately and issues the token naturally --- **Scope & Difficulty:** This is a **targeted, surgical fix** — not a full rewrite. The existing script (which I'll provide in full) already handles: - Redirect/navigation blocking - API interception - Storage protection - Visibility spoofing - Overlay removal - Iframe observation - WebSocket monitoring The missing piece is **hold token lifecycle management** — specifically, acquiring one before the iframe needs it. Its a task for someone experienced with: - Browser network interception (XHR/fetch hooks) - Token-based session flows - Reverse-engineering SPA booking systems - Tampermonkey `@run-at document-start` timing issues - Cross-origin iframe communication (`postMessage`) --- **Important Disclaimer:** The above is my **best guess** based on log analysis. It's possible the actual issue is something else entirely — for example: - A server-side fingerprint check tied to queue completion - A cookie or header that's set during queue exit and validated on `/book` - A race condition where the iframe loads before the page's own Vue/Pinia store is hydrated - A WebSocket handshake that must complete before the widget initializes I'm open to your diagnosis if you find a different root cause. What matters is the end result: **the seating chart iframe must load and stay alive after queue bypass.** --- **Deliverables:** - Fixed/updated Tampermonkey script (`.user.js`) Or Python Script - Brief explanation of what was wrong and what you changed - Tested and confirmed working verified on my side as well at private web mode and shows that the queue bypassed and iframe session is not expired and alive on a event that has a queue --- **Budget:** Open to fair proposals — pay is based on result, not hours. If you fix it in 20 minutes, great, you still get paid in full. **To apply:** Tell me briefly what you think the issue is and how you'd approach it. One-liner "I can do this" replies will be ignored. ---
