| HTTP status | `429` |
| Area | General |
| Problem `type` | `https://docs.nexafone.so/errors/rate_limited` |

Too many requests for this IP address, user or API key. Wait the number of seconds in the `Retry-After` header, then retry. See [rate limits](/v1/rate-limits/).

## What the `detail` says

The `detail` explains the occurrence; it can read, for example:

- Too many callbacks failed verification. Try again later.
- Too many requests. Try again later.

## Handling it

Slow down: wait `Retry-After` seconds, or back off, then retry.

## Example

```json
{
  "type": "https://docs.nexafone.so/errors/rate_limited",
  "title": "Too Many Requests",
  "status": 429,
  "code": "rate_limited",
  "detail": "Too many callbacks failed verification. Try again later.",
  "requestId": "01J9Z8Q4TQ3W6M5V2X7Y8Z9A0B"
}
```

Match on `code`, never on `detail`: the wording may change. See [Problem Details](/v1/errors/).
