Developer tools

Four small helpers for the parts of an integration that are easiest to get subtly wrong. Each one runs entirely in your browser.

Webhook verifier

Paste a delivery and check the HMAC-SHA256 signature and the five-minute timestamp window - or sign a sample with your secret.

SSO JWT builder

Build and sign the inbound single sign-on token (HS256 or RS256), copy the login call, or decode and verify any JWT.

FIX message lab

Compose Logon, order, cancel and market-data messages with correct BodyLength and CheckSum, or parse one from your log.

Request builder

Choose any Partner or Trading API operation, fill the fields and copy the request in nine languages.

Nothing leaves your browser

Signatures, tokens and keys are computed with the browser's own WebCrypto; the pages make no network calls. Still, use test secrets and test keys here, and keep production keys on your servers.
