I can help you build a robust, production-ready EDI integration layer for your 10-minute delivery platform, covering PO creation, acknowledgements, ASN, and invoice sync end-to-end. I’ll design secure REST APIs (JSON/XML) with webhook support, Basic Auth, IP whitelisting, and ISO-8601 UTC handling, while implementing clean validation, GST logic, UOM conversions, batch/HSN/UPC tracking, and async workflows. The solution will include clear error & warning codes (E/W series), partial acceptance handling, and warehouse-ready batch feeds, all backed by readable, well-documented backend code. You’ll receive fully tested endpoints, structured error handling, and complete API documentation (specs, auth, sample payloads, error reference), so vendors can integrate quickly and your team can maintain it easily. I’m ready to start immediately and deliver this in clear, reviewable phases. And also will provide 15 days post completion support for free.
