api_ key_ wrong_ environment
The API key belongs to the other environment.
On this page
HTTP status: 401 Unauthorized. Retrying the same request unchanged fails the same way.
Why it happens
- A sandbox key (ngk_sandbox_…) was sent to the live API, or a live key (ngk_live_…) to the sandbox.
What to do
Use live keys with api.nowgate.io and sandbox keys with sandbox-api.nowgate.io.
Example
The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
