API Calls from Cisco FMC

[NeWGuy1109]

I am trying to test few API Calls from my FMC via the following url :

https://<FMC-IP>api/api-explorer.

i want to run 

GET​/api​/fmc_config​/v1​/domain​/{domainUUID}​/devices​/devicerecords​/{containerUUID}​/bridgegroupinterfaces

GET​/api​/fmc_config​/v1​/domain​/{domainUUID}​/devices​/devicerecords​/{containerUUID}​/bridgegroupinterfaces​/{objectId}

but there is a field which asks for object ID & Container ID which is required to be filled manually.. where can i fined these values for my environment ?
