Let's look at the details.
Is there a test environment?
Yes. Test and Live use separate keys and state. A test order is not proof of live readiness.
Can developers have limited access?
Yes. Technical access is separate from company finances and staff administration.
Where is the API contract?
The existing Letisim documentation covers catalogs, offers, quotes, orders, events and integration examples.
