Create It
Leave outlifetime_seconds and set resources.extendable_lifetime. funded_until is when the current
reservation ends:
+00:00. funded_until moves an hour later at each renewal. If your
available balance can’t cover the next hour, the sandbox ends at funded_until.
Top up automatically or set a
low-balance alert to stay ahead of it. A sandbox paid with your own
provider account has no funded_until.
On a route that can’t extend a lifetime, or when you set lifetime_seconds, BoxRouter reserves the
whole lifetime when the sandbox starts.
What a Reservation Is
A reservation is held from your balance, not spent. It shows asreserved until the provider’s records
set the charge, and the charge is the provider’s cost, never the reservation. A read of the sandbox
says how it is reserved in charge.funding:
