开发者指南以英文撰写，以确保代码、字段名和错误信息与 API 完全一致。
Error shape
{ "status": "error", "message": "amount must be positive", "code": null }message is written for people and can be shown to your staff. Server errors also carry code: "internal_error" and a reference: quote it to support and we can find the exact request.
HTTP statuses
| Status | Meaning | Retry? |
|---|---|---|
| 400 | Validation error: a field is missing or invalid. | No. Fix the request. |
| 401 | Missing, invalid or expired token or key. | After getting a new token. |
| 404 | The charge, transaction or resource doesn't exist for your app. | No. |
| 429 | Rate limit: too many requests or attempts. | Yes, after backing off. |
| 500 | Something went wrong on our side (with a reference). | Yes, with the same idem key. |
For any money movement, retry only with the same idempotency key. That's what makes retries safe.
