POST /v2/parties/external/allocate
The external party must be hosted (at least) on this node with either confirmation or observation permissions It can optionally be hosted on other nodes (then called a multi-hosted party). If hosted on additional nodes, explicit authorization of the hosting relationship must be performed on those nodes before the party can be used. Decentralized namespaces are supported but must be provided fully authorized by their owners. The individual owner namespace transactions can be submitted in the same call (fully authorized as well). In the simple case of a non-multi hosted, non-decentralized party, the RPC will return once the party is effectively allocated and ready to use, similarly to the AllocateParty behavior. For more complex scenarios applications may need to query the party status explicitly (only through the admin API as of now).
