# Error 998: Too Many Requests or Duplicate Action

PayMe's message with `language: "en"`: **Operation is not permitted**

HTTP 429. `status_additional_info` tells the two cases apart: `Too Many Attempts.` is the rate limit, and `Duplicated action detected, please retry later` means the same action is still running.

## Usual causes

- Too many `generate-sale`, `pay-sale` or `capture-sale` calls for one seller.
- A repeat of a refund, capture or withdrawal while the first is running.

## What to do

- Wait for the `Retry-After` time.
- Check the state with a query before repeating a call that moves money. See [Rate limits](/payments/getting-started/idempotency-and-retries#rate-limits).
