Best Practices

Follow these patterns for production-grade, maintainable GST integrations.

Use Sandbox Before Production

Always validate integration against the sandbox environment. The sandbox mirrors production schema exactly. No surprises at go-live.

Set BASE_URL=https://api.sandbox.whitebooks.in/
Handle Token Expiration

Access tokens expire after 3600 seconds. Implement automatic token refresh logic before expiry to avoid 401 errors mid-session.

if (token.expires_in < 300) refreshToken()
Validate Invoice Data

Use the /validate endpoint before submission to catch GSTIN mismatches, invalid HSN codes, and tax computation errors upfront.

POST /api/v2/invoices/validate
Maintain Audit Logs

Store all API request/response payloads with timestamps for compliance audit trails. Include IRN and ACK numbers in your records.

Log: irn, ack_no, timestamp, gstin
