About Our Platform... for technology leaders 💻

Legend Bank provides an API‑first, bank‑owned and controlled platform that operates as the bank’s core for fintech programs. You build against enterprise APIs with a sandbox and Postman collections, integrate via webhooks and event logs, orchestrate ACH, wire and card from a centralized payments hub, and leverage automated settlement operations that keep partner economics precise—without a platform middleman.

Architecture & Data Ownership

• Bank‑Controlled Ledger: Customer and operating accounts reside on a bank‑controlled ledger with settlement to the bank’s core. There’s no external ledger to reconcile and no data transfers required for the bank to access customers, accounts, or transactions.
• Program Segmentation: Every fintech program is logically segregated, including customers, accounts, operating accounts, APIs, data partitions, and access controls. A fintech can only view and manage its own program.
• Real‑Time and Intra‑Day Access: APIs expose real‑time and intra‑day data for both end‑user and fintech operating accounts, enabling instant balances, funding, and servicing workflows.
• Resiliency & DR: Built‑in deposit resiliency, a documented funds‑flow, and bank‑controlled decisioning support DR scenarios in which the bank can provide customer access to funds during contingencies.

API Surface Area & Developer Experience

• API Domains
  • Customer: onboarding, KYC/KYB associations, servicing artifacts
  • Account: creation, configurations (products, features, rates, fees), statements, history
  • Money Movement: transfers, ACH, wires, settlement, reconciliation
  • Card: issuance, lifecycle, spend controls, disputes (via supported partners)
  • Platform: programs, operating accounts, roles/permissions, events, webhooks
• Enterprise Portal & Sandbox: Build quickly with an API portal, sandbox, and Postman collections. Use partner SSO for access. Direct integration support calls are available for complex builds and certification.
• Webhooks & Event Logs: Subscribe to events (e.g., balance changes, payment state transitions, KYC/KYB outcomes). Event logs support replay and troubleshooting.
• Console for Both Bank & Fintech: A shared console provides one version of truth across customer servicing, applications, account servicing, statements, transaction history, payments, operating accounts, case management, event logs, and webhooks.
• Access Control: Role‑based access for bank and fintech teams enforces least‑privilege across API keys, console capabilities, and program data.

Auth Note: Public endpoints and authentication details (e.g., OAuth 2.0/token strategy) are provided during onboarding through the developer portal and implementation guides.

Payments Orchestration

• Centralized Payments Platform: Orchestrate ACH (ODFI/RDFI), wire (ISO), and debit card issuance/processing from a single platform with bank‑defined rules and bank decisioning.
• Universal API or Rail‑Specific Endpoints: Integrate with rail‑specific APIs (ACH, wire) or call a Universal Payments API that applies smart routing to choose the optimal rail based on speed, cost, amount, cutoff, and risk policy.
• Observability & Compliance: Centralized payments provide a consolidated view across programs to strengthen security, reporting, and compliance.

Funds Flow & Automated Settlement Operations

• Defined Funds Flow: End‑to‑end flow from end‑user to bank operating accounts is documented and bank‑controlled.
• Automated Settlement: The platform automates calculations for revenue share, interest, and fees, and posts them to segregated program operating accounts. This reduces reconciliation work, improves auditability, and mitigates “lost money” scenarios common in multi‑system integrations.

Product Configuration by Program

• Program‑Specific Controls: Configure products, features, rates, and fees at the program level, enabling A/B testing and targeted pricing strategies within compliance guardrails.
• Self‑Service Ops: Self‑service capabilities reduce manual interventions for servicing, statements, disputes, case management, and account lifecycle operations.
