Batch Malaysia Tax ID Lookup
Batches SSM numbers or NRICs from your spreadsheet to retrieve Tax ID Numbers for e-invoicing compliance.
What it does
Retrieve Tax Identification Numbers (TIN) for multiple business entities or individuals in a single batch operation. This automation bypasses the LHDN API's one-at-a-time limitation by processing lists of SSM registration numbers or NRICs from your spreadsheet, streamlining data preparation for e-invoicing compliance.
Step by step
- Set up a Google Sheets trigger that fires on row changes or manual execution to initiate the workflow.
- Configure an HTTP request node to send POST requests to the LHDN API endpoint with the required authentication headers.
- Implement a code node that slices the input array of SSM numbers into chunks of 50 to respect batch size limits.
Where the LLM does the work
- Generate robust error handling logic in the code node to distinguish between temporary network failures and permanent invalid TIN rejections.
- Design the data transformation script to map raw LHDN JSON responses back into a clean spreadsheet-friendly format with consistent column headers.
- Create user-friendly notification messages that clearly explain why specific IDs failed validation without exposing sensitive API error codes.
Watch out for
Sensitive personal data like NRICs requires encryption at rest and in transit so ensure your Google Sheets cell protection is enabled.
Batch failures can leave partial results incomplete so add a retry mechanism that logs failed IDs for manual review later.
API response schemas may change without notice so write the parsing code to be resilient against missing or unexpected fields.

You are helping me build the following AI agent workflow. ## Goal Batch Malaysia Tax ID Lookup: Batches SSM numbers or NRICs from your spreadsheet to retrieve Tax ID Numbers for e-invoicing compliance. ## Specification - What it does: Retrieve Tax Identification Numbers (TIN) for multiple business entities or individuals in a single batch operation. This automation bypasses the LHDN API's one-at-a-time limitation by processing lists of SSM registration numbers or NRICs from your spreadsheet, streamlining data preparation for e-invoicing compliance. - Trigger: Run manually (Manual · on demand) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Google Sheets: Input list of SSM and NRIC numbers - HTTP Request: Query LHDN API for Tax ID Numbers - Code: Batch processing logic ## Known pitfalls, handle each one explicitly in your implementation 1. Sensitive personal data like NRICs requires encryption at rest and in transit so ensure your Google Sheets cell protection is enabled. 2. Batch failures can leave partial results incomplete so add a retry mechanism that logs failed IDs for manual review later. 3. API response schemas may change without notice so write the parsing code to be resilient against missing or unexpected fields. ## Reference implementation https://n8n.io/workflows/4781 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Spreadsheet than Google Sheets?
Yes. Google Sheets is only the example spreadsheet in this recipe. The same flow works with Airtable, Baserow and Excel. Swap the spreadsheet connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for finance and accounting teams who'd rather review a draft than build one from scratch.
