Both, but not at the same time. First your test credentials from chiron-acc.vlaanderen.be, which we use to check that the connection works. Then your production credentials from chiron.vlaanderen.be, and only those put your rides in the official ride database.
They are two separate pairs of a Client ID and a Secret. They look identical and they are not interchangeable. Below you will find how to tell them apart and what happens if you mix them up.
Chiron runs on two separate environments. In the test environment, the Flemish government checks whether your software talks to the database correctly. In the production environment, your rides are recorded for real. You register on each environment separately, so each one gives you its own Client ID and its own Secret.
You only request your production credentials once the test has passed. If you were already using other taxi software and are therefore already connected to Chiron, you skip the test phase and only need your production credentials.
A Client ID or a Secret tells you nothing by itself. Both are strings of characters with no visible difference. You recognise them by where they came from.
Nothing you cannot undo. TaxiBuddy checks every pair against the environment it belongs to before anything is stored. If it does not match, you get a message straight away and stay on the same screen.
Three steps, about ten minutes. You need your eID or itsme to sign in.
For the test that is chiron-acc.vlaanderen.be, for production chiron.vlaanderen.be. Sign in with the same method as last time.
Top right under your name you will find Your details. Lost your Secret? Click Renew credentials. The old values expire at that moment.
On the same screen where it went wrong. We put them to Chiron right away, so you see immediately whether it worked.
No. These are two separate environments, each with its own registration. Your test credentials work only on the test environment, your production credentials only on the real database.
No. The ten test messages only serve to check the connection. They never reach the ride database and do not count as a recorded ride.
No. If you were already using other software and therefore already have production credentials, you skip the test. You enter your production credentials straight away and your connection carries on.
No, skip that field. We work with a Client ID and a Secret. The public key is only needed if you work with your own cryptographic keys.
Yes. You register per company, with a separate email address for each one. So every company gets its own Client ID and Secret, per environment.
Let us know and we will update them right away. As long as the old values are in place, your rides do not reach Chiron.
