Environments: testing and production
API v1There is no sandbox host. Testing and production use the same host:
app.tilopay.com. The URL does not tell you which mode you are in.
How the mode is switched#
The mode is switched from the account in the Tilopay portal, not from the integration. There is no parameter, header or alternate URL that changes it from code.
How to verify it#
Tilopay.Init() returns an environment field:
| Value | Meaning |
|---|---|
"PROD" | Production |
"TEST" | Testing |
That is the only signal available at runtime. Read it and surface it in your own checkout while developing.
The real risk#
Because the host is the same, an integrator can believe they are testing while actually
being in production, taking real money. Verify that environment is "TEST" before assuming
you are testing; make an unexpected "PROD" fail loudly in development.
Test cards#
In testing mode you charge with the test cards: each one lists the number, brand, expected result and whether it opens the 3DS challenge screen.
