I need custom code that lets Odoo talk fluently with WhatsApp so that two key interactions run on autopilot: • An order-confirmation message goes out the moment an order hits “Sale Order”. • A smart auto-reply is triggered any time a customer sends a WhatsApp message to our business number. Both flows must be built on the official WhatsApp Business API (already connected to odoo) I’m undecided on whether each sales channel, product type, or customer segment should get its own template, so I’ll rely on your guidance to design the right context logic and template structure. Whatever the final approach, the solution has to let me attach PDFs (invoices, quotations, tickets, etc.) or other small files along with the text when needed. Deliverables: 1. Installable Odoo module with documented source code. 2. Template setup for the two message types, including file-attachment support. 3. Clear README or short video walkthrough that shows how to add new templates and map them to events. 4. Test script or steps I can run to confirm the automation works end-to-end. If you’ve already integrated Odoo with WhatsApp before, please mention the stack you used and any live links or screenshots.

I can help with this, I will build an installable Odoo module that sends order-confirmation messages on "Sale Order" status change and handles smart auto-replies to incoming WhatsApp messages — both via the official WhatsApp Business API already connected to your instance, with PDF attachment support for invoices and quotations. For template routing, I will use a mapping table linking sales channel and product category to specific templates — making it easy to add new ones without touching code. Questions: 1) Which Odoo version are you running? 2) Should auto-replies vary based on keywords in the customer message, or use a single default response? Looking forward to discussing further. Best regards, Kamran

Dear Client, I would love to help you build a reliable Odoo–WhatsApp automation that handles order confirmations and smart auto-replies seamlessly. I am an Odoo Partner, and I have worked on integrations involving Odoo APIs, webhooks, and messaging platforms, including WhatsApp Business API. My approach: I will develop a custom Odoo module that connects cleanly with your existing WhatsApp Business API setup. For order confirmations, I’ll trigger automated messages when a record reaches the “Sale Order” stage, including support for dynamic templates and PDF attachments (invoices, quotations, etc.). For incoming messages, I’ll implement a smart auto-reply system using rule-based logic (customer type, order status, keywords, etc.), ensuring responses are contextual and scalable. I will also design a flexible template system, so you can: Create multiple templates based on product, channel, or segment Attach files dynamically Easily manage and extend templates from the backend The module will include clean, documented code, along with a README or walkthrough for managing templates and testing flows end-to-end. A few questions: Which Odoo version are you using? Are you using Meta Cloud API or a provider like Twilio/360Dialog? Do you need multilingual template support? What kind of auto-reply logic are you expecting (simple vs advanced)? I can also share similar integration experience during discussion. Best regards, Rekha!!!

Hi I can build a clean Odoo module for this, and the main technical challenge is making WhatsApp event handling reliable so order-triggered messages and inbound auto-replies stay synchronized with Odoo records and business rules. I solve that by extending Odoo’s sale and messaging workflows with structured trigger logic, template mapping, and attachment handling tied directly to the official WhatsApp Business API already connected to your instance. I have experience with Odoo customization, Python module development, webhook/event-driven flows, template logic, and document generation/attachment pipelines. I can structure the solution so order confirmations fire automatically on Sale Order status, inbound WhatsApp messages trigger context-aware auto-replies, and PDFs like invoices, quotations, or tickets can be attached when needed. The module will be documented, easy to extend with new templates, and organized so your team can manage mappings and testing without touching core code. Thanks, Hercules

Hi — the real goal here is not just connecting Odoo to WhatsApp, but making sure every message is tied to the correct business event and customer context. A common failure in setups like this is when a sale order changes state more than once, or a document is regenerated, and the customer receives duplicate confirmations or the wrong PDF attachment. I’d build this as a clean Odoo module with explicit event hooks for Sale Order confirmation, a controlled inbound WhatsApp routing layer for auto-replies, and template logic that can expand by channel, product type, or segment without turning into hardcoded rules. The hardest decision early is whether inbound replies stay simple and rule-based or need conversation-aware logic, because that affects maintainability and future scale. I’d lock the event/template model first, then wire attachments and testing around it.

Hi, I understand you need a custom Odoo module that uses the official WhatsApp Business API to automate two critical workflows: sending an order confirmation when a record reaches Sale Order status, and triggering a smart reply whenever a customer messages your business number. The solution also needs flexible template logic, support for PDF and small file attachments, and clear documentation so you can extend it confidently. My approach would be to build an installable Odoo module that hooks into the relevant Odoo events, manages WhatsApp template selection through configurable rules, and supports attachment delivery for invoices, quotations, tickets, and similar files. I would structure the code so message logic remains clean, reusable, and easy to expand for different channels, product groups, or customer segments. The handoff will include documented source code, template setup guidance, and practical steps for end to end verification. Before delivery, I will test event triggering, outbound message delivery, inbound auto reply behavior, template mapping, attachment sending, and module installation flow to ensure the automation works reliably inside Odoo. Best, Justin

Nothing drags down customer experience like slow or inconsistent messaging, especially when orders are coming in and clients expect instant replies. Not having Odoo and WhatsApp working together seamlessly leads to missed confirmations and late follow-ups, which can frustrate your team and your customers alike. With my help, you can expect order-confirmation messages to reach customers instantly and smart auto-replies to handle incoming WhatsApp chats without any manual effort. All of this will work smoothly using your existing official WhatsApp Business API setup. We’ll clarify how message templates should be mapped to channels, products, or segments to fit your business needs. I’ll build and deliver a ready-to-install Odoo module with clear documentation and a walkthrough for future template changes. You’ll get a simple way to test the automation and see it in action from start to finish. Would you like advice on the best way to structure your message templates for maximum clarity and impact?

Hi there, I see you're looking to automate WhatsApp messaging through Odoo, specifically for order confirmations and smart auto-replies. This is a great way to enhance customer interaction while saving time. My approach would involve creating a custom Odoo module that integrates seamlessly with the WhatsApp Business API you already have connected. I’ll ensure that both message flows are efficient and user-friendly, while also allowing for template customization based on your sales channels or customer segments. With 4+ years of experience in software development and API integration, I can create a documented solution that includes clear instructions for adding new templates and mapping them to specific events. One question I have is whether you envision any specific scenarios where different templates might be necessary for various customer segments, or do you prefer a more unified approach?

Interesting project, I will build the Odoo module that fires WhatsApp on Sale Order confirmation, runs a configurable auto-reply on inbound messages, and uploads PDFs through the WhatsApp Media API so attachments ride with the text. The split that matters here: event-triggered outbound needs pre-approved Meta templates with strict variable mapping, while replies inside the 24-hour customer window are free-form session messages with no template at all. I will model both paths so you add templates from Odoo settings without touching code. Questions: 1) Are the order confirmation templates already approved by Meta, or to be drafted? 2) Auto-reply matching by keyword, regex, or default fallback? 3) Odoo version (16, 17, 18) Enterprise or Community? Looking forward to your response. Best regards, Faizan

Hello Client, I’ve read your brief and can build an installable Odoo module that sends an order-confirmation when a Sale Order is confirmed and runs a smart auto-reply for incoming WhatsApp messages using the official WhatsApp Business API you already have connected. I will implement webhook listeners and queued workers in Odoo to ensure reliable delivery, and a clean template model that supports context rules (sales channel, product type, customer segment) with easy mapping to events. Technically I’ll extend Odoo models and use secure API calls to the WhatsApp Business API for text and media messages, implement attachment handling (uploading PDFs/media to WhatsApp or serving via signed URLs), and provide configurable templates stored in the module. I’ll include documented source code, template setup for both flows, a README (and short video if preferred) showing how to add templates and map them, plus a test script/steps for end-to-end verification. Next step: I’ll draft the template schema and event-mapping approach, then implement the module for your review. Which event mapping would you prefer as a starting point: separate templates per sales channel, or shared templates with customer-segment variables? Best regards, Daniel

Bonjour, Je suis convaincu de pouvoir créer un module Odoo performant et prêt pour la production, s'intégrant parfaitement à l'API officielle de WhatsApp Business et automatisant les confirmations de commande ainsi que les réponses aux messages entrants. Fort d'une solide expérience en développement Odoo (Python, ORM, actions serveur et intégrations API), je privilégie les modules fiables et maintenables, fonctionnant de manière optimale dans les flux de travail métiers réels. Je commencerai par analyser votre connexion actuelle à l'API WhatsApp Business et votre configuration Odoo afin de garantir une communication sécurisée et stable entre les systèmes. Ensuite, je développerai un module Odoo personnalisé qui déclenchera l'envoi de messages WhatsApp lors de la confirmation de commande et gérera les événements webhook entrants pour des réponses automatiques intelligentes, incluant un système de modèles flexible pour la segmentation (logique client/produit/canal). Enfin, j'implémenterai la prise en charge des pièces jointes PDF (factures, devis, etc.), fournirai une interface de configuration claire et une documentation complète avec un flux de test pour vérifier l'automatisation de bout en bout. Je vous guiderai également dans la mise en place d'une stratégie de modèles évolutive afin que vous puissiez facilement étendre vos règles de messagerie sans modifier le code source. Au plaisir de collaborer avec vous. Cordialement, Sean

I can help you build a reliable WhatsApp automation layer directly inside Odoo so your key interactions run on autopilot without breaking existing workflows. I’ve worked on Odoo customizations and third‑party API integrations that keep data synchronized and user experiences smooth. My experience includes integrating messaging platforms (such as WhatsApp-style APIs) with Odoo models for leads, orders, and support tickets, plus building custom server actions and schedulers to trigger messages based on defined events or states. This ensures conversations stay consistent and fully traceable in Odoo. I’d start by clarifying your two primary interaction flows, selecting the right WhatsApp API provider, then implementing secure, documented endpoints and Odoo logic to send, receive, and log messages correctly. I would love to chat more about your project! Regards
