HSN Code Lookup API
Resolve an HSN code to its official description.
What the HSN Code Lookup API does
Look up the official description for an HSN code straight from the government master, rather than maintaining a copy that drifts out of date. Useful wherever a product catalogue has to carry a defensible HSN classification. Calls carry your own GST portal API credentials (GSTIN, username and password), so filings are made as you, on your own registration. We never file on our own account.
Popular use cases
- →Validating HSN codes in product and invoice masters
- →Catalogue onboarding for marketplaces and B2B commerce
- →Reducing invoice rejections caused by wrong classification

}Frequently asked questions
Why not keep my own HSN table?
You can, but the master changes and a stale table produces invoices that are rejected or classified wrongly. This reads the live government master.
Does this need portal credentials too?
Yes — it is served through the same GST gateway, so the same API user applies.
