Integrating the DGII eBilling API requires precise handling of XML structures and secure server-side communication to ensure compliance with tax authority standards. I have extensive experience working with PHP and backend integrations, allowing me to handle the request/response cycle and data validation required for this specific API. Over the past 15 years, I have built and maintained complex, custom-coded platforms that go beyond standard CMS templates. My background in PHP, Linux, and software architecture means I can debug connection issues, manage server-side security, and ensure the API integration is stable and error-free. My bid is $435.58 with delivery in 1 days. Send me a message so we can discuss the API documentation and get this integration live.

Hey, I will build the REST API that handles the full DGII e-CF cycle — seed authentication, XAdES-BES XML signing with your .PFX certificate, e-CF submission, and TrackID status polling — starting in the sandbox environment and ready for production certification. One critical detail: I will structure the XML signing layer as an isolated service so certificate rotation or DGII schema updates do not require touching your core invoice logic. This also simplifies the pre-certification review since DGII auditors will see a clean signing flow. Questions: 1) What language/framework does your ERP/POS run on — or is the API standalone? 2) Do you already have your digital certificate and DGII test credentials provisioned? Looking forward to potentially working together. Thanks, Kamran

Hola, Entendemos que el objetivo es desarrollar una API intermediaria que sirva como un puente robusto entre su sistema ERP/POS y los servicios de e-CF de la DGII. Esta API gestionará el ciclo de vida completo: desde la autenticación secuencial (semilla, firma, token) utilizando el certificado digital, pasando por la generación y firma XAdES-BES del XML del e-CF, hasta el envío a la DGII y la consulta asíncrona del estado mediante el TrackID. Enfoque técnico: Proponemos una API REST segura desarrollada en Spring Boot (Java) o Node.js, ideal para las operaciones criptográficas y el manejo de XML requeridos. Expondrá endpoints simplificados para su ERP (ej. /issue-invoice), mientras internamente orquesta las llamadas a los cuatro endpoints de la DGII. Se gestionará el certificado .PFX de forma segura y se persistirán los logs y TrackIDs en una base de datos para auditoría. Módulos clave: Gestor de Autenticación (manejo del token y ciclo de vida de la semilla), Motor de Generación y Firma XML, Gateway de Comunicación con DGII (envío y manejo de TrackID) y un Servicio de Consulta de Estado. Estrategia de implementación: Priorizaremos el flujo de autenticación en el entorno sandbox para validar el uso del certificado. Luego, implementaremos la firma y envío de facturas. Finalmente, construiremos la capa de API para su ERP, asegurando un manejo de errores detallado antes del despliegue a producción. Preguntas: 1. ¿Cómo se proporcionará de forma segura el certificado .PFX y su contraseña a la API en el entorno de producción (ej. variables de entorno, un servicio de vault)? 2. Además de los errores de la DGII, ¿qué lógica de reintentos se espera si hay fallos de comunicación? ¿Debería la API encolar las solicitudes temporalmente? 3. ¿Cuál es el volumen de facturas estimado (diario/mensual) que se espera procesar? Saludos, Rohit

I’ve built similar DGII integrations before, connecting ERP systems to the DGII test and production environments. I’ll handle all steps: getting the seed, signing it with your .PFX certificate, authenticating to get the token, generating and signing the XML invoice in XAdES-BES format, sending it, and tracking the invoice status with TrackID. To ensure smooth error handling, I’ll include clear responses for failures from DGII so your system can respond accordingly. For the REST API, would you prefer stateful session management or stateless token handling? Also, do you have an existing XML schema for your invoices, or should I use the DGII’s standard versions? From previous DGII projects, I know this typically can be set up and tested quickly in sandbox once certificates and access are ready. I will deliver working endpoints with thorough documentation and sample use cases so you can easily integrate and test from your side. Ready to start immediately and get your ERP connected to DGII’s eBilling system efficiently.

Hello, I build LATAM e-invoicing integrations and currently run a DIAN (Colombia) e-invoicing system in production at high volume — the same architecture your DGII project needs: seed/token auth, .PFX/.P12 handling, XAdES XML signing, submission to the tax authority, status polling by tracking ID, and a REST wrapper with proper error handling. To be transparent: my production experience is Colombia's DIAN, not DGII directly. The two share the same structure, so most of your scope transfers. The DGII-specific piece — the Seed → sign → Authenticate token flow, then reception and status endpoints — is a clear delta I can ramp on fast. I'd rather say that up front than overstate it. Approach: DGII auth (seed, sign, token) e-CF generation + XAdES-BES signing Submission + TrackID capture Status inquiry endpoint REST API for your ERP/POS — issue, status, error handling Docs, use cases, source code I'd start in sandbox and get the auth + signing handshake working end-to-end first — that's where most DGII integrations stall; the rest follows quickly. Questions to scope accurately: Which ERP/POS are we connecting, and does it expose an API/DB? Preferred stack — .NET Core or Python? Do you already have the DGII test certificate? Happy to do a walk through the approach and share details of the equivalent DIAN system I run. Best, Deepthi

You need a DGII eCF integration that reliably handles seed signing with your PFX certificate and moves from sandbox to production without invoice duplication or signature errors. Most failed integrations come from fragile certificate handling and poor mapping of DGII error codes into the ERP workflow, not from the HTTP calls themselves. I built Tranero, a tax invoice submission platform that converts ERP records to XML and submits them to a tax authority API with retry handling, signing, and submission logs. Plan - Authenticate using Seed then sign and exchange for token with your PFX - Generate the eCF XML and apply XAdES BES signing - Submit to DGII reception, capture TrackID and persist responses - Provide a status endpoint, error mapping, and a small test harness plus docs and source code You did not list specific questions. To get started I will need sandbox credentials, a sample invoice payload or your invoice template, and access to the PFX or instructions for signing in your environment. Do you expect immediate synchronous confirmation or are you ok with async processing using TrackID callbacks? I will prepare an architecture diagram and test plan once you share sandbox access.

@spodstechno

Hello, I understand you need a DGII e-CF integration that can move from sandbox/pre-certification to production without changing your ERP/POS flow. The critical parts are the seed-based authentication, XAdES-BES signing with the PFX/P12 certificate, XML generation, TrackID handling, and reliable status checks with clear error mapping for your system. I would structure this as a small REST layer around the DGII endpoints so your ERP/POS only calls: - issue invoice - query status - receive normalized DGII responses This keeps DGII-specific complexity isolated, makes testing easier, and reduces production risk during certification. One important detail: will your ERP/POS send me the invoice data in a fixed JSON schema, or do you need help defining the XML-to-REST mapping as well? If you want, I can outline the integration flow and deliverable structure next.
