Frequently asked questions
Why pick WhiteBooks over Finagg for embedding GST APIs?
WhiteBooks is a standalone GSP-certified API platform — its commercial model is built around developer / enterprise API consumption. Finagg is primarily a supply-chain finance product; its GST tooling exists to enable its core finance flow, not as a general-purpose compliance API.
Do both have e-Way Bill support?
WhiteBooks ships a full e-Way Bill API (generate, extend, cancel, Part-B update, multi-vehicle, consolidated EWB) with NIC compliance certificates and PHP / Java / Node / Python SDKs. Finagg can produce e-Way Bills as part of its broader invoice-finance workflow but does not publish a standalone EWB API surface.
Are both GSP-certified?
WhiteBooks is GSP-certified (direct GSTN / NIC / IRP connectivity). Finagg uses a partner GSP for the compliance steps inside its supply-chain finance product, so embedding their stack as a pure GST API for a third-party ERP isn’t their commercial focus.
Where is the SLA published?
WhiteBooks publishes 99.99% SLA with credits at whitebooks.in/status and a public 30/90-day uptime history. Finagg has not published a public SLA for its compliance tooling at the time of writing.
Which one is faster to integrate?
WhiteBooks ships with a free public sandbox at apisandbox.whitebooks.in, OpenAPI 3.0 specs at /openapi/*, and first-party SDKs in Java / Node.js / Python. Most ERP teams complete the sandbox-to-production migration in a single sprint. Finagg integration typically goes through a sales-led pilot programme.
