GoFundNode developer portal
Everything you need to integrate a buyer application against the GoFundNode v1 API: submit typed jobs, hold and settle fiat-denominated credits, and receive signed webhooks.
The canonical contract is
docs/V1-API.md in the repository — it is the source of truth for every endpoint, field, and status code. This portal is a task-oriented companion; where anything here disagrees with docs/V1-API.md, the latter wins. The official SDK is @gofundnode/vendor-client (packages/vendor-client/README.md in the repository).
Payments are fiat-first (ADR-046). Customer credits are a consumptive, single-issuer, non-transferable, non-redeemable prepayment denominated in fiat. There is no token, wallet, self-custody, or stored value. An inbound Solana Pay USDC rail exists as a preserved payment-continuity exception (ADR-047), reconciled to fiat credits — it is not the primary GA customer rail and is off unless explicitly enabled. See Credits & account snapshot.
