Unlocking the Potential of API Integration for E-Invoicing in Malaysia

The Inland Revenue Board of Malaysia (IRBM) has initiated an e-invoicing mandate, requiring businesses to submit their invoices in a structured digital format. This transition is being rolled out in phases, with the first phase targeting enterprises with an annual turnover exceeding RM 100 million. At the core of this initiative is the MyInvois platform, which facilitates real-time validation of transaction data.

To meet the varying needs of businesses, the MyInvois platform offers two integration models: the MyInvois portal and API integration. While the portal caters to smaller businesses with limited transaction volumes, API integration is indispensable for large enterprises seeking to streamline operations and maintain compliance. This blog delves into the intricacies of API integration, its pivotal role in Malaysia’s e-invoicing ecosystem, and the specific APIs offered through the Software Development Kit (SDK).

The Role of API Integration in E-Invoicing

API integration bridges the gap between a business’s internal systems and the MyInvois platform. It enables seamless data exchange, real-time validation, and automation of core e-invoicing processes, including document submission, validation, retrieval, and tracking. By automating these processes, APIs eliminate the need for manual intervention, reduce errors, and accelerate transaction workflows.

Let’s take a closer look at how API integration aligns with the Malaysian e-invoicing process:

Document Preparation: Taxpayers configure their systems to generate invoices in XML or JSON format, adhering to the MyInvois’s data structure requirements.

Submission: Once a transaction is finalized, the system submits the invoice payload to IRBM for validation.

Real-Time Validation: MyInvois validates the document almost instantly. Errors are flagged for correction, while validated invoices are shared with suppliers and buyers.

Rejection and Cancellation: Buyers and suppliers can raise rejection or cancellation requests within a 72-hour window after validation.

Archival: Validated invoices are stored in IRBM’s database, ensuring compliance with record-keeping regulations.
