# Malaysia: validation rules

Find the rule behind a rejected Malaysian e-invoice and correct it. Start with the document type you sent and the errors returned by Unify or LHDN.

A Malaysian e-invoice is checked twice. Unify checks the GETS request against LHDN’s requirements before anything is submitted. LHDN then runs its own [document validation rules](https://sdk.myinvois.hasil.gov.my/document-validation-rules/) when the document reaches MyInvois.

## Check the GETS request

Select **Malaysia** and the document type in the [field reference](https://docs.complyance.io/countries/my/fields/). The **Requirement** column shows which GETS fields are mandatory, optional or conditional. In **List with sample request**, choose the document type and inspect the fields for that selection. Use values from the invoice and the company’s registration records.

## Read a `422` response

A `422` response from Unify lists each failed rule in `errors`. `code` is the rule ID from the table below, `getsPath` names the GETS field to correct and `message` describes the rule. Correct the source data, then send the document again. See [Unify errors](https://docs.complyance.io/api-reference/unify/errors/) for the response format.

## Read LHDN’s result

After the `200`, [follow the document](https://docs.complyance.io/api-reference/unify/submit-and-retrieve/#follow-the-document) until `isTerminal` is `true`. `final_valid` means LHDN validated the document. `final_invalid` means LHDN marked it invalid; `government` holds LHDN’s answer with the reason.

LHDN’s checks cover the document structure and core fields, taxpayer identities, references on credit and debit notes, codes, duplicate documents, currency and exchange rates. Check the current [MyInvois code tables](https://sdk.myinvois.hasil.gov.my/codes/) when a code is rejected. For a credit or debit note, check that the invoice it refers to is valid in MyInvois. For a taxpayer error, confirm the identifiers against the company’s registration records. Do not replace a rejected identifier with a guessed value.

## Every rule Unify checks

These are the 173 rules Unify applies to a Malaysian GETS request, with the message you get back and the field it points at. `MY-*` codes are Unify’s checks of LHDN’s requirements. `IBR-*`, `ALIGNED-IBRP-*` and `BR-*` codes come from the Peppol rules and apply with the `peppol` modifier. **Applies to** shows the document types, modifiers or variant each rule belongs to. A receipt (`is_receipt`) skips the buyer checks.
