\# How to prevent a payment from being charged back? It is not possible to avoid all chargebacks; however, you can reduce the probability of having a payment charged back by following these recommendations: 1\. \*\*Keep all the business data in your account up to date\*\* so that your buyers can recognize you. 2\. Add the Mercado Pago security script to your page and replace the \`view\` value with the name of the section (e.g., home, search, item) \`\`\`html \`\`\` > WARNING > > Attention > > If you don't have a value available for the section, you can leave it empty! 3\. Be sure to add all payment and customer details as name, address, and payment method in the \[Create payment\](https://www.mercadopago.com.mx/developers/en/reference/online-payments/checkout-api-payments/create-payment/post) request. 4\. \[Send the payment voucher\](https://www.mercadopago.com.mx/ajuda/16170) to your customer via e-mail or text message. ## Fraud Alert We'll let you know via IPN or Webhook notifications any time we notice irregular activity or there's a fraud alert on your account. In this situation, you must \[cancel the purchase\](https://www.mercadopago.com.mx/developers/en/docs/sales-processing/cancellations-and-refunds) and return the money to the buyer to avoid a dispute. Configure and enable \[IPN\](https://www.mercadopago.com.mx/developers/panel/ipn) or \[Webhook\](https://www.mercadopago.com.mx/developers/panel/webhooks) notifications on your dashboard to receive alerts for irregular behavior by enabling \*\*Fraud Alert\*\* (\`delivery\_cancellation\`). > NOTE > > Important > > When charging with \[Point\](https://www.mercadopago.com.mx/developers/en/docs/mp-point/landing), review the buyer's details and always request an ID.
