Transfers
Move money between two wallets in your organization, the wallet to wallet transfer action.
A transfer moves money from one of your wallets to another in the same
organization, instantly. There is one operation: it lives under the source
wallet, at POST /v1/wallets/:id/transfer, where :id is the wallet the money
leaves. Transfers settle synchronously, the 201 already carries
status: "completed" and the acuinf…trf reference.
Read the conventions first: the envelope, auth, idempotency, and
pagination are assumed across every operation. Transfers require the transfer
scope (not wallet) and an Idempotency-Key.
