WhatsApp Notify — send your invoices on WhatsApp (official Cloud API)

The channel your customers actually read

Email gets lost, WhatsApp gets read — often within minutes. WhatsApp Notify sends your invoices and reminders straight to your customers' WhatsApp, from Dolibarr, through Meta's official Cloud API.

One click, or fully automatic

• 'Send on WhatsApp' button on the invoice.
• Optional automatic send on invoice validation.
• The invoice PDF goes as an attachment.
• Real-time delivery tracking: sent, delivered, read — colored badge on the invoice, updated by the webhook.

A real, official integration

Most WhatsApp modules out there are just 'web.whatsapp' links (manual) or paid third-party gateways. This one uses Meta's official Cloud API: approved template messages, automated server-side sending, reliable delivery statuses.

Highlights

• WhatsApp send button on the invoice + automatic send.
• Invoice PDF attached.
• Sent / delivered / read tracking (HMAC-SHA256 signed webhook).
• International numbers normalized to E.164 (configurable dial code).
• No external dependency (pure cURL, no Composer, no SDK).

Requirements

• A Meta Business account + a WhatsApp Business number (Cloud API).
• A Meta-approved message template (Document header for the PDF, body with 3 variables: customer, reference, amount).
• Dolibarr 18 to 23, PHP with the cURL extension.

Note: Meta charges per conversation/message (paid directly to Meta). Opening the account and the first template are free.
