The EV Roaming Tester has one public API. It is the HTTP surface you automate with an API key against the deployed service:
All operations live under /api/v1 and authenticate with a Bearer API key that starts with evrt_. There is no other supported base URL and no environment selector.

​
What you can automate

Only the operations in the API reference section of this site are public API. Everything else the application does (the interactive simulator, entity editing, account and key management) is browser functionality, not part of this contract.

​
Authentication

Every request sends the key in the Authorization header:
API keys are created and revoked in the app, in Settings, then Security, and require a paid plan. There is no API for managing keys: a key cannot mint, list or revoke other keys. See Create an API key.

​
Response envelope

Every response is JSON. Successes wrap their payload:
Errors carry an HTTP 4xx or 5xx status and a message:
Two statuses deserve a special mention because CI scripts get them wrong:
  • A 202 means the work was accepted and is still going. It is not a success verdict and not a failure. Poll or wait for the result instead of gating on it.
  • A 503 on a charging journey start means our runner is unavailable. It is a statement about our service, never a verdict about your partner’s implementation.
The full status-code table is in Troubleshooting.

​
Limits and usage

Plans set ceilings on connections, active API keys, runs per minute and runs in flight. Read your own numbers instead of hardcoding them:
The response reports your tier, active connections against their cap, active keys against their cap, in-flight and per-minute run ceilings, and your report retention window. A request over a ceiling returns an explicit 429 with a Retry-After header. An in-flight charging journey holds one run slot until it reaches a terminal state, and a run waiting on a recovery decision keeps holding its slot until you decide.
