Lithic Developer Documentation

Build with Lithic

Card issuing, money movement, and program management — everything you need to launch a payments product, in one modern API.

Four ways to get up and running — from your first request to production traffic.

Bring Lithic into Cursor, Claude Code, Copilot, and other AI editors — search docs and run live API calls in flow.

Every endpoint, parameter, and webhook — with copy-pasteable examples in your language of choice.

A safe environment mirroring production — run cards, transactions, and webhooks end-to-end.

Authentication, environments, rate limits, and idempotency — the fundamentals every integration needs.

Guides and references, grouped by what you're building.
