...records, where it will query specific rows either on a scheduled basis or on-demand, convert the resulting dataset into a clean JSON payload with simple key-value pairs matching a provided schema, and then deliver that payload to a remote endpoint via an HTTP POST webhook authenticated with a bearer token. The solution, which can be written in Python, Node.js, or PHP for reliable operation on a Linux server, must implement parameterized queries or ORM usage to eliminate SQL injection risks, store all credentials securely in external configuration files or environment variables, and include a robust retry mechanism with exponential backoff and comprehensive logging for any failed webhook deliveries that don't return a 200 OK response. The deliverable should include well-comme...

I need the full OpenClaw package downloaded with your own VPE/VPS resources, then handed over so I can install it on my Windows machine—and ideally any other device I might switch to later (Mac or Linux). No extra configuration is required on your side; I just want a clean, ready-to-run build. Along with the files, record a concise video tutorial that walks me through: • where you sourced the download • how to verify its integrity • step-by-step installation on Windows, plus any notes that make the process transferable to Mac and Linux Feel free to use any screen-recording tool you like, just keep the explanation clear and easy to follow. When we’re done, I should have the installer (or a zipped folder) and a video link or MP4 that I can repl...

...JSON payload, and • Push that payload to a remote endpoint via a standard webhook (HTTP POST with a bearer token). The table structure is already in place; I will explain the field names you should map. The JSON shape has to match a small schema I’ll share, but it is simple key-value pairs—nothing nested beyond one level. Code can be in Python, Node.js, or PHP as long as it runs reliably on a Linux server. Use parameterised queries (or an ORM if you prefer) so there is zero risk of SQL injection, and make sure any credentials sit in an external config file or environment variables. The webhook must return a 200 OK; if it does not, the job should retry with exponential back-off and log the response for review. Deliverables: • Source code with clear inl...
