Authentication

Celcoin uses OAuth2 client credentials. The server automatically manages token refresh.

Sandbox / Testing

Celcoin provides a sandbox at sandbox.openfinance.celcoin.dev. Set CELCOIN_SANDBOX=true to use it.

Without CELCOIN_SANDBOX, the server calls Celcoin production at api.openfinance.celcoin.com.br (up to 0.2.3 the default was api-sec.celcoin.com.br, a host that does not exist). Celcoin accepts production calls only over mTLS, with a certificate Celcoin issues, and only from IPs you registered with them in advance (Celcoin docs). From any other IP the token call answers 401 "O seu IP ou certificado digital nao foi reconhecido". This server does not present a client certificate, so in production point CELCOIN_BASE_URL at a proxy that holds the certificate and terminates the mTLS; called directly, production answers that 401.
