e-Invoice archive: store validated MyInvois e-Invoices with a readable PDF copy

For each e-Invoice your ERP or middleware submits to LHDN MyInvois, keep the validated record and a branded PDF with the QR code in SharePoint.

The problem

After e-Invoicing went live, finance teams have XML/JSON records in one system and PDFs customers ask for in another, with no single archive.

The outcome

A searchable archive per customer and month, with the validated UUID, status and PDF together — ready for audits and customer queries.

Before you start

  • An e-Invoice solution already integrated with LHDN MyInvois (most ERPs and middleware vendors provide this). This flow does not submit e-Invoices to LHDN itself.
  • A Word template for the visual invoice, including a placeholder image for the validation QR code.

Build it step by step

  1. Receive the validated record — Your middleware calls the flow's HTTP trigger with invoice data, the MyInvois UUID, long ID and status.
  2. Build the validation link — Compose the public validation URL your middleware returns (or that LHDN specifies) and turn it into a QR image if the middleware doesn't supply one.
  3. Generate the PDF — Adobe PDF Services Generate document merges the JSON into the Word template, including the QR code, and outputs PDF.
  4. Archive — Save to e-Invoices/<customer>/<yyyy-MM> with columns: invoice no., UUID, validation date, status, total.
  5. Send to customer — Optionally email the PDF to the customer's billing address.

Connector action names are shown as they appear in Power Automate at the time of writing; Microsoft and Adobe occasionally rename actions or add new versions.

Error handling

  • Secure the HTTP trigger: restrict who can call it (the 2025+ trigger options allow Entra ID–only callers) and validate a shared secret header.

Licensing

  • HTTP trigger is premium. Adobe PDF Services is per transaction.

Variations

  • Handle cancellations: when the middleware reports a cancelled e-Invoice, update the status column and stamp the PDF 'CANCELLED' with Adobe PDF Services.
