Contracts, not production authority

These versioned examples describe the current payment and refund DTOs. They do not activate a country, provider, credential, tenant, aggregator programme, or live execution mode.

Choose the environment deliberately

Sandbox rehearses deterministic outcomes with synthetic identities and no real funds. Live access is unavailable until country-cell, provider, commercial, security, capacity, and operational approvals all pass.
