The DodoPayments TypeScript API Library is a server-side client that provides convenient access to the Dodo Payments REST API from TypeScript or JavaScript. Generated with Stainless, it ships with a typed API surface, including TypeScript definitions for all request params and response fields. Install via npm and use a simple client initializer with an optional bearer token and environment toggle (live_mode or test_mode). The library supports common payment workflows (e.g., checkout sessions) and exposes full API coverage described in the docs. Error handling is centralized through APIError subclasses mapped to HTTP status codes (BadRequestError, AuthenticationError, NotFoundError, etc.). Requests can be retried by default (2 retries) with exponential backoff, configurable globally or per request. Timeouts default to 1 minute and can be customized; APIConnectionTimeoutError is thrown on timeout, and timeouts are retried. List endpoints are paginated with for await…of support, and helper methods exist to fetch pages incrementally. Advanced usage enables access to raw Response data via asResponse() or withResponse(). Logging is configurable via logLevel and supports custom loggers, and custom fetch implementations and fetchOptions are supported (including proxies for Node, Bun, and Deno).
