Beyond payments, Fintech Core manages the customers a venture serves and their banking primitives. Full request/response schemas live in the API Reference.

​
Clients

Register the people and businesses you serve:
  • POST /api/v1/clients/person — individual (KYC fields, contact, nationality).
  • POST /api/v1/clients/company — business (registration, tax, address).
  • GET /api/v1/clients / GET /api/v1/clients/{id} — list and fetch.
Each client carries KYC status, risk level, and blacklist/blocked flags.

​
Onboarding

/api/v1/onboarding captures the KYC/KYB details for a client — source of funds, occupation, expected volumes, verification status, and the current onboarding step — and exposes the overall status.

​
Accounts

Open and manage accounts for a client (/api/v1/accounts): create, fetch, list, check balance, and move through states (activate, freeze, close). Balances track available, current, and reserved amounts.

​
Beneficiaries & transfers

  • /api/v1/beneficiaries — saved payment recipients (IBAN/BIC or account/SWIFT/routing), validated on entry.
  • /api/v1/transfers — bank transfers (SEPA, SWIFT, domestic, …) with a status workflow and a unique_reference for safe retries.
Use the API Reference tab to try any of these endpoints with the built-in playground.
