GraphQL API 的工作原理

curl -X POST https://transactional-graph.staging.fluzapp.com/api/v1/graphql \
  -H "Authorization: Bearer <ACCESS_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query GetSpendAccount($id: UUID!) { getUserCashBalanceById(userCashBalanceId: $id) { nickname availableCashBalance } }",
    "variables": { "id": "9c1f6b2e-4d7a-4c3b-9f11-2a5e8b0d6c74" }
  }'

{
  "data": { "wallet": { "balance": { "value": 12500, "currency": "USD" } } },
  "errors": null,
  "extensions": { "requestId": "req_01H..." }
}
