FIELD NOTE
The SDK is part of the operating contract
HASiL's 17 July 2026 SDK 1.0 release notes introduce new document versions for the e-Invoice Special Voluntary Disclosure Programme and clarify tax-exempt transaction treatment. The notes advise taxpayers and service providers to update integrations to support the applicable versions.
This is not a reason to change production blindly. It is a reason to have a release process that can identify affected document types, run representative test cases, and record which version was approved for use.
FIELD NOTE
Build a change-control loop
The technical team should connect the SDK release feed to the people responsible for tax operations, finance, support, and integration maintenance.
- Subscribe to official release signals
- Keep document fixtures under version control
- Test tax-exempt and SVDP cases separately
- Record environment and API version
- Reconcile after every integration release
FIELD NOTE
Do not confuse a document update with advice
A specification can explain what the system accepts; it does not decide what your business should report. Keep the boundary clear between technical mapping, accounting policy, and tax advice.
That separation makes the implementation more credible and gives operators a place to escalate uncertainty instead of hiding it inside code.
DIRECT ANSWERS
Questions operators ask
Why do SDK release notes matter to a business user?+
Because a document or validation change can affect whether an integration submits, rejects, or records a transaction correctly.
Should a business implement every new document version immediately?+
Review the official applicability, test the affected workflow, and coordinate with finance or a qualified adviser before enabling a version in production.
