What is the WhiteBooks GST API?

The WhiteBooks GST API is a REST API set that lets developers file GST returns, fetch GSTR-2B, search GSTINs, and look up HSN / SAC codes programmatically. Authentication is API-key + OAuth2; the OpenAPI 3 spec is published in the developer portal.

How do I get sandbox access?

Request sandbox credentials at /about/contact-us. You receive a sandbox API key and a sample GSTIN within one business day. The sandbox mirrors the production endpoints so you can build and test end-to-end without touching real GSTINs.

What data formats does the API support?

All endpoints accept and return JSON. Bulk operations also accept multipart CSV uploads. Errors follow a consistent shape: HTTP status + error code + human-readable message.

Is rate-limiting applied?

Yes. Sandbox is rate-limited to 60 requests per minute per key. Production rate limits depend on plan; enterprise plans support burst rates and dedicated capacity. Throttle responses use HTTP 429 with a Retry-After header.

How is the API priced?

Pricing is per-call with volume tiers. Contact info@whitebooks.in or request a demo for a quote based on your monthly call volume and which endpoints you need.
