WhatsApp Weekly Vehicle Checklist – Developer Specification

@codefusion53

Hi I can build this WhatsApp only weekly vehicle checklist as a reliable state based workflow with automated Friday reminders photo rules by vehicle type cloud storage naming PDF generation and Excel tracking updates. I focus on automation systems where completion rules and enforcement are strict and the process must resume exactly where the user stopped. I will implement a webhook driven WhatsApp flow where each driver is identified by phone number and each checklist runs as a state machine tied to the vehicle plate and ISO week. The system will ask the questionnaire step by step enforce required notes when any item is not OK then request the mandatory photo set with validation and guided prompts so drivers upload the correct angles. Media will be saved into the exact folder structure with system generated filenames and the final PDF will be created only when all requirements are met. Reminders will run on a schedule and will always check status before sending. Excel tracking will update automatically to green red or yellow and can include a link to the folder or PDF. The solution will be built modular so storage provider and Excel target can be swapped between Drive OneDrive or S3 and Google Sheets or Microsoft Graph. Best, Justin

Timeline: 10 days | Cost:€700 | Proven experience Hello . I’ve solved this exact problem before and can deliver a WhatsApp-based weekly vehicle checklist system with automated reminders, photo validation, and cloud storage in 14 days. Based on my past experience, the real challenge is not sending messages, just ensuring the state machine correctly tracks each driver’s progress and enforces all photo and questionnaire rules. On a similar project, careful state handling and automatic PDF generation prevented incomplete submissions and streamlined reporting. To proceed, I only need your Excel VEHICLES_MASTER file, preferred cloud storage setup, and WhatsApp Business API credentials. This is a straightforward project for me, and I’m confident in delivering a fully automated, compliant, and trackable vehicle checklist system. Happy to go into more detail in the chat.

Hello, I’m excited about the opportunity to contribute to your WhatsApp-based weekly vehicle checklist system. With strong experience building WhatsApp-driven, webhook/state-machine automations and integrating cloud storage plus Excel tracking (via Microsoft Graph or Google Sheets API), I can deliver a robust flow that enforces completion exactly as you described—questionnaire + conditional notes + mandatory photo set by vehicle type + validated storage + PDF generation—before a checklist is ever marked complete. I’ll implement the Friday scheduler and reminder enforcement (08:00/13:00/17:00/19:00) with status checks before every message, keep each checklist as a resumable state machine per vehicle/ISO week, and auto-generate the required folder structure, photo naming, and checklist PDF with links to stored photos. The WEEKLY_CONTROL sheet will be updated automatically on every status change (✅ green, ❌ red, ⚠️ yellow for issues) with optional links to the PDF/folder, while VEHICLES_MASTER remains the source of truth for assignments and rules. You can expect clean, documented code, reproducible configuration (reminder times, storage provider, Excel target), and a reliable system that prevents “partial” submissions from slipping through. Best regards, Juan

Hi there. This works when each driver has a resumeable WhatsApp state flow tied to one vehicle and one ISO week, with strict completion gates for answers, required photos, and PDF generation. Pitfalls are duplicate webhook events, missing or wrong photo counts by vehicle type, timezone mistakes for Friday reminders, ISO week rollover edge cases, cloud folder naming drift, and Excel update conflicts. First I will ingest your VEHICLES_MASTER file into a small database, then build the checklist state machine with webhook handlers plus validation rules and a scheduler that checks status before each reminder, then generate the PDF and upload photos with system filenames into the required folder structure and update WEEKLY_CONTROL on every status change. Which WhatsApp provider will you use and do you already have a verified WhatsApp Business API number and templates approved? Should the tracking sheet be Google Sheets or Microsoft Excel on OneDrive, and which cloud storage do you prefer for folders and PDFs? I have built WhatsApp automation flows with state machines, media capture validation, scheduled reminders, PDF generation, and Sheets Graph updates with idempotency and audit logs. I can start today, get one vehicle end to end running fast, then scale to all vehicles and hand you a clear readme. Danylo Podolskyi

@Zeeshan0489

Hi there, I’ve read your WhatsApp Weekly Vehicle Checklist spec and I’m confident I can deliver a robust, automated solution that runs on the WhatsApp Business API with stateful checklists, photo validation, and seamless Excel tracking. I have deep experience in building end-to-end automation pipelines, API-driven workflows, and cloud storage integrations that ensure data integrity and timely reminders for drivers. What you’ll get: a state-machine driven flow that creates a weekly checklist every Friday at 08:00, automated reminders at 13:00, 17:00, and 19:00 if incomplete, and a strict validation that all questionnaire fields and required photos are completed before marking a checklist COMPLETED. Photos are organized in a deterministic cloud folder structure and a generated PDF includes all metadata, answers, and links to photos. The WEEKLY_CONTROL sheet automatically reflects status with color codes and optional links. Next steps: I can sketch the data mapping from VEHICLES_MASTER to the WhatsApp flow, outline the API endpoints for photo validation and PDF generation, and deliver a working prototype within a short 1-2 week sprint after I review the Excel schema in detail. Best regards,
