Getting started

Sandbox

How sumu_test_ keys differ from sumu_live_ keys.

A sumu_test_ key and a sumu_live_ key run through the same request pipeline. Schematron validation, UBL generation, AS4 transmission, and SMP publishing behave identically regardless of which key you use — there is no simulation mode.

What differs

  • Rate limits: sumu_test_ keys get 120 requests/minute and 5,000/day; sumu_live_ keys get 600/minute and 100,000/day — see Rate limits.
  • Host: a sumu_test_ key only works against a non-production deployment, and a sumu_live_ key only works against production — mismatching either returns a 403 FORBIDDEN_ERROR.

Sending real data

Beyond the rate limit and host lock above, nothing in the request pipeline changes behaviour based on key type — check with SUMU before sending real party data through a sumu_test_ key. Treat "sandbox" as a different host and rate limit, not a guarantee that nothing leaves the building.
