# Error 513: Duplicate Purchase PayMe's message with `language: "en"`: **Duplicate purchase attempt detected. Please wait one minute before retrying** PayMe refused a saved-card charge (`generate-sale` with `buyer_key`) because the same card was charged for the same seller, amount and currency within the last 60 seconds. This check is off unless PayMe turns it on, so most integrations never see this code. ## Usual causes - A retried or double-submitted saved-card charge. ## What to do - Check the first charge with a query before you retry. It may have succeeded. See [Saved Cards](/agents/steps/saved-cards). The full list of codes is on [Errors](/payments/getting-started/errors). If something else is going on, see [Troubleshooting by Symptom](/agents/errors/troubleshooting).
