Code generation

A single request

Code snippet turns the request on screen into runnable code, in thirteen languages: cURL, HTTP, JavaScript, Python, Go, C#, Java, Ruby, Rust, PHP, PowerShell, Dart, and a Claude prompt.

It is generated from the same request the engine sends — so what you copy is the request you just watched work, not a reconstruction of it. That includes the headers the client adds, which is usually what is missing when a snippet does not reproduce a result.

Resolve variables substitutes {{name}} for real values. Leave it off to keep the placeholders — and note the warning that appears when a resolved snippet contains secrets, before you paste it into a chat window.

A whole suite

Export as script produces a standalone Node file. No Sendwire, no dependencies beyond Node itself.

Your scripts are carried across verbatim. The exported file ships a small sw shim implementing the same API, and your pre-request and post-response code runs unchanged inside it.

That is worth being precise about, because the alternative is worse. An earlier version tried to translate scripts into declarative steps, and anything it could not express — an HMAC signature, a loop, a conditional — silently became a TODO comment and a dropped header. Running the same JavaScript means there is nothing to fail to express.

node checkout-flow.mjs

It exits non-zero when an assertion fails, shares cookies across steps, and prints results in the same shape as the command line — so it drops into CI as it is.
