Hi,
 WhatsApp Integration with Odoo – Step-by-Step Guide
    1. Select Your API Provider
    To integrate WhatsApp with Odoo, you can either use Meta's official WhatsApp Cloud API or opt for third-party services such as 360Dialog or Twilio.
    If you go with the Cloud API, you’ll need to:
        Set up a WhatsApp Business account
        Obtain your Access Token, Phone Number ID, and Business Account ID from Meta’s developer portal
    2. Install a WhatsApp Integration Module
    You’ll need to install a suitable integration module in Odoo. There are various community-developed modules available depending on the Odoo version you're using.
    Visit apps.odoo.com to explore available options. These can serve as good starting points for your implementation.
    3. Configure Your API Credentials
    Once the module is installed, head to the configuration section in Odoo and:
        Input your API credentials (token, number ID, etc.)
        Set up webhooks so you can receive WhatsApp messages directly into Odoo
    4. Create & Manage Message Templates
    WhatsApp only allows business-initiated messages using pre-approved templates. You’ll need to:
        Design and submit message templates for approval in Meta's developer dashboard
        Once approved, configure these templates in Odoo for use in automated communications
    5. Automate WhatsApp Messaging in Workflows
    Odoo’s built-in automation tools like:
        Server Actions
        Scheduled Actions
        Custom Python Code
    ...can be used to trigger WhatsApp messages for events such as:
        Order confirmations
        Payment follow-ups
        Shipping notifications
    6. Receive and Monitor Customer Replies
    By configuring webhooks, inbound messages can be routed back into Odoo. These can be displayed and managed within:
        The Discuss app
        CRM records
        Or any custom chat module you may have developed
    You can also set up two-way messaging capabilities depending on your integration design.
Hope it helps
