Flows
End-to-end use cases for Core — ledger accounting, card issuing, and payouts.
A flow is a complete, end-to-end use case that composes several Core concepts together. While the Concepts section answers "what is a ledger account, card, or spending control?", flows answer "how do I post a settlement, issue a card, or disburse a payout?".
Core flows are grouped by the kind of operation they describe:
- Ledger operations — moving money inside Core's books, including transfers between subaccounts with or without currency conversion.
- Issuing — creating cards and provisioning them to digital wallets.
- Payin — getting money into subaccounts: top-ups, static-key collection, per-payment intents, and settlement.
- Payout — getting money out of a ledger account.
