Jewellery E-Invoice & E-Way API

@anshumanvermaUK

Hi, I can build a clean and efficient REST API with endpoints for e-invoice, e-way bill, and GST owner lookup supporting both XML and JSON payloads. I’ll ensure API-key based security, proper validation, and fast, container-ready architecture with clear documentation. Thanks Anshuman

Hello, I hope you are doing well. I can definitely build a clean, container-ready REST API for your jewelry billing system with endpoints for /einvoice, /ewaybill, and /gstowner. My approach would be to create a lightweight API service that accepts both XML and JSON payloads, processes them efficiently, and returns validated responses, including ARN, e-way bill numbers, or GST owner details. I’ll structure the code with clear documentation and API-key header security and provide Postman/Swagger collections for easy testing and integration. Two quick questions: 1) Which government e-invoice / GST API provider will the service integrate with (NIC, ClearTax, or another gateway)? 2) Do you prefer the API to be built using Node.js, Python (FastAPI), or another stack that fits your deployment environment? Best regards, Rajat J

I see you’re developing a jewellery-specific billing system and need a clean REST API to handle e-invoices, e-way bills, and GST owner details. You want a solution that accepts both XML and JSON payloads, secured by an API-Key header, and easy to containerize. Your project requires three endpoints: /einvoice, /ewaybill, and /gstowner, each returning validated responses including government-issued ARNs and GST profiles. You also want clear documentation with a Postman or Swagger collection and a setup guide for local and staging environments. I have built similar PHP-based REST APIs integrating XML and JSON processing for billing and tax automation, delivering well-structured code with clean folder hierarchies and thorough comments. I’ve created endpoints that interact with government APIs and return validated responses, along with detailed Postman collections and deployment instructions, ensuring seamless integration and testing. I can complete this API within 10 days, ensuring all endpoints work perfectly with your XML/JSON jewellery billing files. Let’s discuss any specifics to align the implementation precisely with your needs.

I will build a lightweight, container-ready REST API using Node.js (Express) or Python that supports both XML and JSON inputs for generating e-invoices, e-way bills, and GST owner lookups. The service will include secure API-key authentication, clean modular code structure, and fast validation handling. I’ll provide fully documented endpoints, Swagger/Postman collection with sample payloads, and a clear setup guide for local and staging deployment. The solution will be optimized for easy integration with your jewellery billing system and quick scalability.

Hi, I’m a backend developer with experience in REST API design, JSON/XML processing, and government-compliant integrations (GST/e-invoicing workflows). I can build a clean, fast API with the required endpoints: /einvoice → generate e-invoice + return ARN /ewaybill → create e-way bill from same payload /gstowner → fetch GST owner details instantly The API will support both XML and JSON inputs, secured via API-Key header, and structured for easy containerization (Docker-ready). You’ll get: • Well-structured, commented source code • Validated request/response handling • Swagger/Postman collection (XML + JSON examples) • Clear setup guide + README for local/staging deployment I’ll focus on performance, clean architecture, and reliability, so your billing system can plug in smoothly. Let’s build this solidly — just message me

Hello, A jewellery billing API that touches IRP for e-invoicing and e-way bills needs the payload validation tight from the start — the government portal returns cryptic errors if field formats don't match exactly, and debugging that mid-project costs more time than getting it right upfront. Here's what I'd deliver: Three clean endpoints (PHP + lightweight framework): - /einvoice — accepts XML or JSON jewellery billing payload, calls IRP, returns ARN in validated response - /ewaybill — same source data routed to e-way bill generation, returns EWB number - /gstowner — GST number lookup returning registered owner details instantly Security: API-Key header on every endpoint — no other auth complexity added. Deliverables: - Clean source code, clear folder structure, commented throughout - Postman + Swagger collection with sample XML and JSON jewellery-billing calls - Setup guide + README: API-Key config, local and staging run instructions - Containerisation-ready structure I'll test all three endpoints against your sample billing files before handover — ARN, EWB number, and GST profile all verified correct. Quick question — are you connecting to the live IRP sandbox or a third-party GST service provider API?

Hello, Your project is very clear and well-structured, and I’d be happy to build a clean, scalable REST API for your jewellery billing system. I have strong experience designing and developing APIs with a focus on performance, clean architecture, and maintainability. I can build the required endpoints (/einvoice, /ewaybill, /gstowner) with full support for both JSON and XML payloads, ensuring consistent and validated responses. Here’s how I would approach your project: * Design a clean, modular API structure (controllers, services, validation layers) * Implement API-Key based security for all endpoints * Handle both XML and JSON parsing seamlessly * Ensure fast and reliable responses, ready for production use * Provide Swagger/Postman documentation with real examples * Deliver a clear setup guide and README for easy deployment (Docker-ready) I’m comfortable using Laravel, Node.js, or FastAPI depending on your preference, and I’ll make sure the API is lightweight, well-documented, and easy to integrate into your system. Looking forward to working with you and delivering a robust solution.

Hi, I built exactly this — REST APIs with clean structure, Postman collections, and proper docs. I built OmniSell Pro, a production SaaS that includes a complete invoicing system with GST/VAT calculations, PDF generation, and third-party API integrations. I understand billing systems deeply. For your jewellery e-invoice + e-way bill API: - POST /einvoice — accept XML/JSON, return government-issued ARN - POST /ewaybill — generate e-way bill from same source data - GET /gstin — fetch registered owner details instantly from the GST number - API-Key header authentication - Postman collection with sample XML/JSON calls - Quick README for local + staging setup - Clean folder structure with clear comments I can deliver all 3 endpoints in 5-7 days. One question — which e-invoice API provider are you using? (NIC, Cleartax, Mastergst, etc.) This helps me confirm the exact payload format. Muhammad Fakhar

Hi, Your vision for a centralized, automated real-estate CRM is clear, and this is exactly the kind of system I build. I specialize in backend systems, API integrations, and automation, and have experience developing platforms that handle lead pipelines, external data sources, and real-time workflows. For your CRM, I would focus on: Automated lead capture, scoring, and assignment API integrations for listing data + real-time buyer/seller matching Web scraping for unsupported portals Workflow automation (alerts, reminders, email sequences) Scalable backend with clean data handling and reporting dashboards Suggested stack: Node.js/NestJS or Laravel backend, React frontend, with scalable API architecture. Timeline: MVP in ~1 weeks (aligned with your goal) Given the scope, I’d prefer to discuss a fixed-price or phased approach, but I’m open to starting within your hourly range for initial work and planning. I can share relevant work and propose a clear architecture before we begin. Let’s build a system your team will actually rely on daily. Best regards, Dusan
