The key above is a shared sandbox demo key from the original quick-start. It only works against test data and is rate-limited. Replace it with your own test key from the portal.

Testing against staging (v1)

Historically, integration testing for v1 ran against https://staging.acmepay.duckdns.org/v1/, protected with HTTP basic auth. Ask the infrastructure team for credentials. The v2 sandbox has since replaced this workflow.
