The goal is to build a WhatsApp bot that delivers automated responses focused on invoicing. When a user sends a specific keyword or command, the bot should connect to my invoicing API, generate a new invoice, verify the user’s account / order details, and immediately send the finished document back through the same chat. After delivery, it must keep listening so the user can ask for status updates; the bot will query the API and reply with the current state of that invoice. I will supply full API documentation, authentication keys, and message templates for greetings and confirmations. Preferred tech stacks are Node.js or Python together with the official WhatsApp Business Cloud API or Twilio’s Conversations API, but I’m open to alternatives if you have production-ready experience with them. Deliverables • Source code with clear README for local setup and deployment • Secure integration with the invoicing API (generate, send, track) • User verification step before any invoice action • Simple log or dashboard that shows every invoice request and its status • Brief video or written walkthrough proving the flow on a live number Acceptance criteria: the bot must generate, send, and track at least three test invoices during a live review; responses should land in WhatsApp within five seconds of each trigger. This is the API

Greetings, Do you already have a test WhatsApp Business number available for development, or should our team set up a sandbox environment for the bot first? Our understanding is that you need a WhatsApp bot, built in Node.js or Python, that listens for keywords/commands, verifies the user, connects to your invoicing API to generate invoices, delivers them back through WhatsApp, and continues to track status updates on demand. The solution must include secure API integration, logging or a simple dashboard for invoice tracking, and a walkthrough video demonstrating live invoice generation and status queries. Our team has experience building production-ready WhatsApp bots with Twilio Conversations API and the WhatsApp Business Cloud API, integrating external APIs securely, and providing maintainable, documented code with deployment instructions. We ensure fast response times, user verification, and robust logging for operational visibility. For quick coordination, please click the chat button as our team is available most of the time. FYI, the current bid amount is a placeholder for proposal submission. Looking forward to connecting via chat. Regards, Yasir LEADconcept PS: Let me know, if you want to see our team past work to determine our skills/expertise or past customer's references.

Hi, I can build a secure, production-ready WhatsApp invoice automation bot using Node.js or Python with the official WhatsApp Business Cloud API or Twilio Conversations API. I’ve implemented similar webhook-based bots that generate documents, validate users, and return files in real time with reliable logging and status tracking. My approach would be: • Webhook listener to capture incoming WhatsApp messages • Keyword/command parser with validation logic • Secure API integration to generate invoices • User verification step before any invoice action • Immediate PDF/document delivery back to WhatsApp • Status query handler to fetch live invoice state • Lightweight dashboard (or admin log view) to track all requests I’ll ensure responses are delivered within 5 seconds by using async processing, optimized API calls, and proper webhook handling. Security will include token validation, signature verification, and environment-based secret management. Deliverables will include clean, well-structured source code, a clear README for deployment, and a live demo walkthrough generating and tracking at least three invoices. Estimated timeline: 10–14 days depending on API complexity. I can start immediately and follow a milestone-based delivery plan. Best regards

Hello, I will build the WhatsApp invoice bot using Node.js and the WhatsApp Business Cloud API, with keyword-triggered flows for invoice generation, user verification, and status tracking through your invoicing API. The bot will stay in a persistent listening state so users can query invoice updates anytime within the same conversation. For the webhook handler, I will add a message queue with retry logic so that if your invoicing API is slow or briefly unavailable, no request gets lost and the user still receives a response within the five-second window. Questions: 1) Does user verification happen against your invoicing API, or is there a separate auth system? 2) Should the log dashboard be a simple web page, or do you need it inside an existing admin panel? Let us discuss via chat. Best regards, Kamran

I will implement a simple dashboard or log for all invoice requests, ensuring secure, reliable operation. Source code will include a clear README and deployment instructions. I have experience delivering production-ready WhatsApp automation systems with sub-5-second response times. Clarification Questions: Should the bot support multiple simultaneous users, or will only single-user testing be required initially? Are invoice notifications limited to WhatsApp, or do you also want optional email copies for users? Thanks, Asif

Hello, I have carefully reviewed your project details and understand that you need a WhatsApp bot that can generate invoices through your API, deliver them instantly to users, and provide real time status updates through chat. With strong experience in backend automation, API integrations, and chatbot development, I can confidently build a reliable solution. First, I will design the bot workflow using Node.js or Python integrated with the WhatsApp Business Cloud API or Twilio Conversations API to handle message triggers and commands securely. Next, I will implement a verification layer that validates the user account or order details through your invoicing API before allowing invoice generation. The bot will then call the API endpoint to create the invoice and immediately send the generated document back through the WhatsApp conversation. Then, I will build a status query handler so users can request invoice updates, where the bot fetches the current state from the API and responds instantly. I will also implement structured logging to track all invoice requests and responses. Finally, I will provide clean source code, a documented README for deployment, and a walkthrough showing the full workflow on a live number. Would you like the logging system as a simple dashboard or structured log file? Let’s connect in chat so I can review the API and start building the bot. Best Regards, Aneesa.

Hello, I’m excited about the opportunity to contribute to your project. With my experience building WhatsApp automations in Node.js/Python and integrating secure, production-grade APIs, I can deliver a bot that validates the user first, generates an invoice on command through your invoicing API, and returns the finished document back into the same WhatsApp chat within your 5-second response target. I’ll tailor the implementation to the official WhatsApp Business Cloud API or Twilio (whichever best matches your current setup), and keep the bot stateful so users can request status updates at any time and receive accurate, real-time responses from the API. You can expect clean source code with a clear README, an auditable log/dashboard for every invoice request and status change, and a concise walkthrough proving at least three live test invoices end-to-end.

Hi, From what you described, the flow is straightforward but needs to be built properly: listen for a trigger, verify the user, call your invoicing API, generate the invoice, send it back in WhatsApp, and continue handling status requests without breaking the session. I would build this using Node.js with the official WhatsApp Business Cloud API. It’s reliable, production-ready, and avoids unnecessary third-party layers. If you prefer Twilio, I’m comfortable with that as well. ✔My approach would be: - Set up a secure webhook to receive WhatsApp messages - Verify the user before any invoice action - Connect securely to your invoicing API (using env-based credentials) - Generate and retrieve the invoice document - Send the PDF or link back through WhatsApp within seconds ✔I’ll also include a simple log dashboard or structured log view where you can see: - Phone number - Invoice ID - Action taken - Current status - Timestamp I’ve previously built WhatsApp bots connected to payment and internal APIs, where response speed and reliability were critical. Keeping responses under five seconds is realistic with proper async handling. ✔You’ll receive: - Clean, well-structured source code - README with setup + deployment steps - Secure API integration - Live demo proof with at least three test invoices generated and tracked Before starting, I’d just confirm how user verification should work and whether your API returns a direct PDF or a URL. Thanks Sagar

Hi, As per my understanding: You need a WhatsApp bot that automates invoicing workflows. When a user sends a specific keyword or command, the bot should verify the user, connect to your invoicing API, generate an invoice, and send the completed document back through the same WhatsApp chat. After delivery, the bot must continue listening for follow-up queries such as invoice status, fetch updates from the API, and reply instantly. The system should include secure API integration, logging or a simple dashboard for tracking requests, and clear documentation. Implementation approach: I will build the bot using Node.js or Python integrated with the WhatsApp Business Cloud API (or Twilio if preferred). The bot will detect keywords, trigger user verification, and securely call your invoicing API to generate invoices. Once generated, the document will be returned through WhatsApp along with confirmation messages. I will implement status-check commands that query the API and respond with the latest invoice state. Additionally, I’ll add logging or a lightweight dashboard to track requests and responses. The final deliverable will include clean source code, deployment instructions, and a walkthrough demonstrating the full workflow. A few quick questions: Will invoices be returned as PDF files or links from the API? What method should be used for user verification (order ID, phone match, token)? Do you already have a WhatsApp Business Cloud account configured?
