Enable Cashout API

The cashout API is off by default. Turning it on is a one-time setup.

1. Ask Finomesh to enable the cashout API for your gateway. This is a platform-controlled setting — you cannot switch it on yourself. Once it is enabled, a Cashout API section appears on your gateway → Settings.
2. In that section, click Generate signing secret and copy it — it is shown once and stored encrypted; it can never be read back. Store it as securely as your API key.
3. Add your server IPs under Server IP allowlist — API access (the cashout API shares this list with API checkout mode). An empty allowlist blocks all cashout calls.

A secret is required to open the API

Until a signing secret exists, cashout requests are rejected — enabling the gate alone does not open the API.
