# Listrak Data Import API

> REST API for importing commerce data — customers, orders, products, reviews, and rating summaries.
> Base URL `https://api.listrak.com/data`. Auth: OAuth2 client_credentials at `https://auth.listrak.com/OAuth2/Token` (Bearer token).
> This documentation is plain markdown, designed to be fetched and read directly by coding agents.

## Start here
- [Getting started](https://api-docs.tools.listrak.com/dataimport/guides/getting-started.md): authenticate and post your first batch - every body is a JSON array
- [Authentication (OAuth2)](https://api-docs.tools.listrak.com/dataimport/guides/authentication.md): client_credentials flow with Data Integration credentials; 401 is the only auth failure
- [Errors & retries](https://api-docs.tools.listrak.com/dataimport/guides/errors.md): only 201/400/401 are declared; a 400 rejects the whole batch with no per-record detail
- [PII & logging](https://api-docs.tools.listrak.com/dataimport/guides/pii-logging.md): the most PII-dense API in the set; log customerNumber/orderNumber/sku, never bodies
- [Copy-paste client & recipes](https://api-docs.tools.listrak.com/dataimport/guides/recipes.md): full Python + TypeScript batching client, nightly sync order, product and review shapes
