Sign-Then-Stamp API · For Digital Signature Platforms

Your users sign. Kenal stamps. The flow never breaks.

In Malaysia, a signed instrument isn't enforceable until it's stamped. When your customer's signature completes, hand the PDF to Kenal via the Partner API — stamping runs through STSDS, certificate comes back to your record. Your users don't bounce to MyTax.

What changes for your customers

Their contract finishes in your product. Sign, stamp, done — no context switch.
Certificate comes back to the same record your platform already owns.
LHDN queries handled offline by our team. Your customer doesn't triage stamping support.

What changes for your customers

Their contract finishes in your product.

Sign, then stamp — done. Without a context switch to MyTax or a separate login.

Certificate comes back to the record.

The same record your platform already owns. No separate filing system for stamped documents.

LHDN questions handled offline.

Our team handles appeals and post-submission queries. Your customer doesn't have to triage stamping support.

What changes for your business

Sticky workflow.

Users who sign and stamp in your product don't evaluate alternatives for the stamping half.

Commercial differentiation.

Competitors routing users to MyTax look incomplete next to a platform that handles both.

Referral commission.

Commission on every customer you introduce, per the partnership agreement.

The things that go away

"After you sign, go to MyTax to stamp" in your help docs.

User drop-off between signature and enforceability.

The competitive vulnerability where a user evaluates a signing platform that bundles stamping.
