Hello, I have experience working with WhatsApp integrations, REST APIs, and automation workflows using Node.js and Python. For your requirement, the official WhatsApp Business/Cloud API does not support sending messages directly into WhatsApp groups as a personal number, so the most reliable approach would likely be a companion-device or WhatsApp Web automation layer connected to your ERP through REST endpoints. I can help: • Analyse the best stable approach for personal-number group messaging • Build a lightweight REST integration layer for your ERP • Support text, images, videos, and attachments • Implement token/session handling and webhook flows • Provide deployment documentation and maintenance notes for Linux servers The solution can be built in Node.js with a clean API structure and straightforward deployment. Estimated timeline: • Functional prototype: 3–5 days • Final tested hand-off + documentation: 1–2 weeks Thanks, Chris

Hello, I understand you need a WhatsApp integration layer connected to your ERP that can post directly into existing WhatsApp groups while preserving your personal number as the visible sender. The real challenge here is that the official WhatsApp Business/Cloud API does not natively support sending messages into normal WhatsApp groups using a personal identity. In my experience, the most stable solution is usually a companion-device or WebSocket-based gateway approach that keeps the personal number authenticated while exposing secure REST endpoints to the ERP. This avoids the limitations of standard business APIs while maintaining group functionality. I previously worked on WhatsApp integrations using Cloud API, unofficial gateway layers, Node.js automation services and webhook-based messaging systems. One implementation included media delivery, session persistence, queue handling and ERP-triggered group notifications through authenticated companion-device architecture. My approach would be to first evaluate the safest delivery method for your use case, then build a lightweight REST integration layer with text/media endpoints, followed by token/session management, rate-limit handling and deployment documentation for Linux environments. A functional prototype would typically be ready within a few days depending on the selected integration method. Thank you.

@mojjammil

Hello, I am ready to dive into your project immediately. I’ve worked with WhatsApp Cloud API, Baileys, and device-linked gateway setups for ERP/CRM integrations, and in this case the official Business API won’t support posting into groups as a personal sender, so the stable approach is a companion-device session using a persistent Node.js service with webhook-driven REST endpoints. I can build the middleware for text/media delivery, session recovery, queue handling, and Linux deployment while keeping the ERP integration lightweight and fully documented for long-term maintenance. I want to discuss with you in more detail. Kind regards, Mojjammil

@MuhammadAhsan98

✋ I can first help you validate the best WhatsApp integration approach for group messaging from a personal number before building the ERP integration layer ✋ I reviewed your requirements carefully and the important detail here is the “send as personal number inside WhatsApp groups” requirement. Official WhatsApp Business Cloud APIs do not natively support posting into regular WhatsApp groups as a personal sender identity, so the solution will likely require a stable companion-device or session-based gateway approach rather than a standard business API implementation. I can help you build this in a reliable and maintainable way. The system can be designed cleanly so your ERP only communicates with a lightweight API layer while the WhatsApp session handling remains isolated and manageable. Let’s connect and discuss the ERP environment, expected message volume, and preferred hosting approach so we can structure the integration properly from the beginning.

@ukokab

I have analysed your requirement in detail. The official WhatsApp Business API does **not** support sending messages to groups. To achieve group delivery **with your personal number as the sender**, the only **practical, maintainable approach** is to build a custom integration using an **unofficial gateway** that operates via **WhatsApp Web**. This preserves your number and allows full control over text, images and videos. I propose the following stack: * **Core driver**: **WhatsApp Web** based driver (e.g., `waweb-js` / `Baileys` / `WPPConnect`) – widely used, well‑documented, and avoids heavy browser automation. * **Middleware layer**: A lightweight **Node.js** service that exposes a **REST API** for your ERP to call. * **Delivery endpoints**: `POST /send/text` (group ID, message), `POST /send/media` (group ID, file URL / Base64). * **Deployment**: Docker container on your Linux server – single command to run. All messages appear in the target group **from your personal number**, exactly as if you had sent them from WhatsApp Web. The service is self‑hosted, respects WhatsApp’s rate limits, and includes a session manager (QR‑based pairing, persistent credentials). I will also provide a small **discovery endpoint** that lists all groups your number belongs to, so your ERP can select the group dynamically. Best, Usman K

@ihorz5

Hi, this is Ihor from Ukraine. I've reviewed your project requirements and understand that the key challenge is enabling reliable WhatsApp group messaging directly from your ERP while preserving your personal phone number as the visible sender for both text and multimedia content. Since the official WhatsApp Business API has limitations around personal-number group messaging, selecting the right architecture and compliance-safe workaround will be critical. My approach will involve evaluating the most stable integration path, including WhatsApp Cloud API limitations, companion-device solutions, and reliable automation gateways that can operate through your personal number while still supporting ERP-triggered REST/webhook communication. I will build a lightweight integration layer with endpoints for text, image, and file delivery, implement authentication/token handling, and provide fully documented deployment and maintenance instructions for your Linux environment. A few additional questions: Q1: Is the ERP hosted on-premise or on a cloud Linux server? Q2: Do you already have a dedicated phone/device available for WhatsApp pairing and automation? Q3: Approximately how many messages or media uploads are expected daily to help evaluate rate-limit considerations? Q4: Would you prefer a fully self-hosted solution, or are you open to third-party gateway services if they provide better stability? Best regards,
