I already have an app that creates PDFs as a copy of governmental system and embed a QR that currently points back to my own domain. What I now need is modify on my app , once scanned, to land users on the official GOSI ([login to view URL]) verification page and show the identical document so they can download the same PDF directly from the government site. I have zero API or documentation from GOSI, so the task involves analysing the network traffic, headers, tokens, and any hidden form data the verification page expects, then replicating that logic in a small service or script I can host. The job is finished when: • Scanning the QR opens the GOSI verification page (not a proxy or iframe) with the correct parameters automatically filled. • The page immediately displays the matching record and offers the “Download PDF” option for that file. • The solution works on mobile and desktop without requiring the visitor to log in. • You provide clear, reusable source code (Python, Node, or similar), a brief setup guide, and notes on any endpoints or tokens used so I can maintain the flow. If you can also suggest caching or graceful-failure handling, that’s a plus. Tell me which tools or techniques you plan to use and how quickly you can turn this around.

Hi there, I can analyze your current QR verification flow, inspect the requests, headers, tokens, and form parameters used by the official GOSI verification process, and update your application so the QR code redirects users to the official GOSI verification page with the required data passed automatically whenever technically supported. I'll provide clean, well-documented source code, setup instructions, and implement graceful error handling to make the solution reliable and easy to maintain. Before I begin, can you confirm whether the official GOSI verification page can already locate the document using information embedded in the QR code, or does your current system store additional data that will need to be mapped during the redirect? Kindly drop me a message to discuss more in detail. Thanks.

Hi, — this is really an undocumented verification-flow replication problem, not just a QR change, and I’ve built enough production integrations to know where these flows usually break. The real engineering risk is session and token coupling on the GOSI side: if the verification page expects short-lived state, hidden fields, or anti-automation headers, a simple redirect will fail intermittently on mobile and desktop. I usually structure this in two parts: first map the exact browser exchange from QR entry to record display and PDF download, then isolate the minimum reproducible parameter set in a small Python service or script. If the flow is direct-linkable, keep it simple; if it is stateful, I recommend separating token acquisition from redirect generation so failure handling is explicit. The closest work here is Custom Feature Development & Integration, where I dropped into an existing product, audited the codebase, implemented targeted logic, and handed off maintainable documentation. I’d also add graceful fallback around expired tokens, changed form fields, and verification mismatches so the app degrades cleanly instead of sending users into a dead end. These systems need to survive upstream changes, not just work once. If useful, I can first sketch the request chain, identify which fields are deterministic versus session-bound, and tell you whether this can be done as a pure redirect or needs a lightweight broker. Thanks, Hercules

Hi, I understand exactly what you're trying to achieve. Before committing to development, we'll first analyze the GOSI verification flow by inspecting the network requests, headers, tokens, and request sequence to determine whether this can be implemented reliably without official APIs. If the verification flow is technically feasible, we'll build a clean solution that automatically redirects users to the official GOSI verification page with the required parameters, works across desktop and mobile, and includes well-documented Python/Node source code, setup instructions, and graceful error handling. We have solid experience with reverse engineering web flows, network analysis, automation, Node.js/Python, and integrating with third-party systems where official APIs aren't available. We'll also review the attached PDF to understand the QR structure and verification process before proposing the implementation. Let's connect and review the sample together. If the workflow is technically possible, I'm confident we can deliver a reliable solution quickly. Rajesh

Hi, I understand you want to create a QR code that directs users to the GOSI verification page with the correct record displayed, allowing direct PDF download without login. This involves reverse engineering the verification process by analyzing network traffic and hidden form data, then recreating that logic in a script or small service. I plan to use Python for network analysis and scripting, leveraging requests and possibly Selenium if needed to simulate form submissions. The script will generate a URL with the necessary parameters, open the GOSI page, and ensure the matching record is shown with a download option. I will also include caching strategies to improve reliability and graceful failure handling for network issues. The source code will be clear, reusable, and include setup instructions, along with notes on any tokens or endpoints involved. I can deliver this within 5 days, depending on the complexity of the verification flow. Do you have any samples of how the verification page behaves, or specific records you want to target initially?

Hi, I can help with the safe and legitimate part of this workflow, but I would not replicate hidden GOSI traffic, bypass undocumented verification logic, or generate links that make a third-party PDF appear as an official government-hosted document without an approved integration. What I can do is review the current QR/PDF flow and build a compliant verification approach: the QR can open the official GOSI verification page, pass only publicly supported parameters if GOSI allows them, and provide a fallback page explaining how the user can verify the document manually. If GOSI has an official verification URL format, API, or approved partner process, I can integrate that cleanly and document it. I can also improve your app so each generated PDF has a clear audit trail, secure QR metadata, caching, graceful failure handling, and source code that is easy to maintain. If needed, I can help identify the correct public GOSI contact/process for requesting API or verification access. Question 1: Do you have any official GOSI-issued verification link format from the original PDF QR? Question 2: Is the goal to verify documents that already exist in GOSI’s system, or documents generated only by your own app? Regards, Houssame

Hi there, Your QR currently resolves to your own domain, but the requirement is a direct GOSI verification flow with the matching PDF download on gosi.org.sa. I’ve spent the last 4 years solving exactly this type of problem: reverse-engineering verification journeys, mapping hidden form fields, and reproducing server-side request sequences. I’ve delivered similar fixes where QR-based document checks were redirected to official portals with stable parameter handling and clean fallback logic. The real risk here is not the redirect itself; it’s reproducing the exact session, token, and header sequence the GOSI page expects without breaking on mobile, desktop, or future updates. I’ll inspect the page flow, capture network requests, identify required tokens or anti-forgery values, and build a small service/script that generates the official landing URL and preserves the lookup path. I’ll also add graceful failure handling and caching for repeated lookups. I’ll keep the code isolated, documented, and easy to deploy in Python or Node, with notes on each endpoint and parameter involved. Best regards, John allen

I understand you need the QR in your PDFs to redirect users straight to GOSI’s official verification page, showing the exact document and allowing PDF download—no login required, just seamless access. Since there’s no public API, I’ll start by analyzing GOSI’s network requests and forms during verification. I’ve done similar work before, where I reverse-engineered undocumented government portals to automate verification steps without user logins. I’ll identify required tokens, headers, and parameters, then build a lightweight service in Node or Python to generate URLs or auto-submit forms that land users directly on the correct record page. For caching, I recommend storing recent queries temporarily to reduce load and speed up response. For graceful failure, the script can fallback to a message with manual instructions or retry logic. Do you expect the PDF’s embedded data to change often? That affects caching design and token validity checks. I can deliver clean source code, docs, and setup instructions within 3-4 days. Let me know if you want me to share initial findings from my network traffic analysis as I start. Ready to begin when you are.

Hey, the part that'll bite here isn't finding the certificate number parameter — it's that GOSI's verification page almost certainly issues a short-lived CSRF token or session cookie before it'll render any record, so a plain QR redirect with query params alone will land on a blank or error state. I'd stand up a thin relay endpoint that pre-fetches that token via a headless request, then immediately bounces the visitor to GOSI with everything pre-seeded. What fields does your current QR encode — just the certificate number, or additional identifiers?
