Sandbox & testing

Every account gets a sandbox alongside production. Use a test key (qsk_test_…) and your calls run against a simulated environment:

• No real documents are created, no emails are sent, nothing is charged.
• No quota is consumed — hammer it as much as you like while building.
• The API shapes and responses match production, so code written against the sandbox works unchanged with a live key.

The Playground in the Developer portal fires real requests with your test key so you can explore endpoints interactively before writing a line of code.

Tip

Switch from sandbox to production by swapping qsk_test_… for qsk_live_… in the X-Api-Key header — nothing else changes.
