Guides for your language

Each guide is a complete program you can run as it is: it reads its input from disk, calls the API, reports errors and saves the file. TypeScript and Python use the SDKs; every other language needs nothing but its standard library.

Every program on these pages was run in its language’s own toolchain against a stand-in for the API, with a valid key and with a refused one, and every webhook receiver against correctly signed, tampered and outdated deliveries.
