A rule watches a custodial wallet account (`trigger`) and, when funds become available on it, transfers them to a target (`action`) — most commonly a sweep to a non-custodial wallet destination. Rules match at the account credit, not at the deposit rail: fiat deposits settle into the issued bank account's settlement wallet account, so a rule on that wallet account catches ACH/SEPA/SWIFT deposits, stablecoin deposits, and internal transfers alike. The action target reuses the money-movement vocabulary (`account` for the customer's own accounts, `destination` for recipient destinations). At most one non-archived rule may watch a given trigger account. Statuses: `active ⇄ paused → archived` — pause and resume through PATCH, archive (terminal) through DELETE. - name: sandbox x-displayName: Sandbox description: Simulate supported account, task, capability, and transfer outcomes. - name: institutions x-displayName: Institutions description: List institutions referenced by capabilities and applications. - name: webhooks x-displayName: Webhooks description: Configure webhook endpoints and inspect delivery activity. externalDocs: description: Swipelux Documentation url: https://docs.swipelux.com paths: /v3/sandbox/customers/{customerId}/verification: post: tags: - sandbox summary: Simulate customer verification description: >- Approve or reject an individual KYC or business KYB review in sandbox.
