Overview - Bob Payments

Bob offers official SDKs in two layers. They solve different problems and are typically used together: a server library creates the charge and verifies webhooks on your backend; the frontend SDK mounts the checkout and tokenizes the card in the browser.

Credit card is still coming soon. Today the SDKs operate with PIX; card tokenization in the Checkout SDK arrives when card is launched.

Choose your SDK

SDK	Layer	Language / Platform	When to use
Node.js SDK	Server (backend)	Node.js / TypeScript	Create charges, list transactions, and verify webhooks from your server.
PHP SDK	Server (backend)	PHP	The same, on PHP stacks.
Checkout SDK	Frontend (browser)	JavaScript / React	Embed Bob’s checkout on your site, tokenize the card, and run 3DS without exposing raw card data.

Secret keys (sk_live_, sk_test_) only exist on the server. Checkout session creation happens on the backend with a server library; the Checkout SDK runs in the browser and only receives the checkoutToken.

Typical flow (server + frontend together)

Your backend  ── Node.js/PHP SDK ──>  creates the checkout session (sk_...)
                                      │
                                      └─ checkoutToken ─> your frontend
Your frontend ── Checkout SDK ──────>  mounts the checkout, tokenizes the card, runs 3DS

No SDK for your language?

All operations are available through the REST API — the SDKs are conveniences on top of it. See the API Reference and call the endpoints directly from your backend in any language.
