Finish Tawseel SAUDI TGA API Integration

The Saudi TGA Tawseel REST API still has gaps inside my proprietary SaaS delivery backend, so I need an engineer who can step in part-time, review the existing code, and drive the integration to completion. Current state • Core backend is already live but built on an internal framework, not Laravel / Node / ASP.NET. • Authentication, Order Management, and Delivery Tracking endpoints all return errors or inconsistent data. • A full audit across every endpoint is required before going live with regulators. What has to happen 1. Inspect the current connector, identify where it diverges from the official Tawseel specification, and patch the code. 2. Complete any missing endpoints, including edge-case flows documented by TGA. 3. Create and run Postman (or comparable) test collections that prove every request/response fulfils the spec, including HTTP status codes and JSON structure. 4. Push fixes through Git, with clear commit messages so my internal team can follow the change history. 5. Supply a concise hand-off note summarising changes, test evidence, and any remaining risks. Tech environment REST, JSON, HTTP, Postman, Git. Familiarity with Laravel, Node.js, or ASP.NET is helpful for reading reference snippets, but the live code sits inside a proprietary stack, so flexibility is key. Prior experience integrating logistics or government services is a strong plus. Acceptance criteria • All Tawseel endpoints pass automated tests. • Authentication token flow remains stable for 24 h under sandbox load tests. • Order creation, status updates, and delivery tracking round-trips match the official examples byte-for-byte. • No 5xx responses during the final validation session. To respond Share one or two similar API projects, your hourly rate, and how many hours you estimate you’ll need for audit, fixes, and final validation. A concise Gantt or milestone outline is welcome so I can slot the work into our deployment calendar.
