\# Troubleshooting Below, you can find a list of problems that may occur during your integration and operation with Mercado Pago Point, and how to solve them. > SUCCESS\_MESSAGE > > If you are experiencing a problem with Mercado Pago, before resorting to the information in this documentation, make sure that all our services are working correctly by accessing our \[real-time status report\](https://status.mercadopago.com/). :::AccordionComponent{title="The terminal does not change the operation mode to PDV"} If you made the operation mode change of your terminal to PDV mode via API and you don't see it reflected, you will need to restart it. Remember that each update made to the operation mode of the terminals requires restarting them to complete the process. ::: :::::AccordionComponent{title="POS mode integration that stopped working"} If your integration stopped working momentarily, this may be due to some unexpected interruption in our payment APIs. While we work to restore the service, and only temporarily, you can continue with payment processing with Mercado Pago Point by changing the operation mode of your terminal to \`STANDALONE\`, which is the mode not integrated with our APIs. For this, you have three options: do it via API, via terminal, or via Mercado Pago Panel. Choose the one that best suits your needs. ::::TabsComponent :::TabComponent{title="API"} Send a \*\*PATCH\*\* to the endpoint :TagComponent{tag="API" text="Change operation mode" href="/developers/en/reference/in-person-payments/point/terminals/update-operation-mode/patch"} using the Access Token that corresponds according to your integration type (:toolTipComponent\[personal\]{link="/developers/en/docs/mp-point/create-application#bookmark\_access\_credentials" linkText="Access credentials" content="Mercado Pago Point integrations to your system for your own use and configured using your application's production credentials. For more information, access the link below."} or :toolTipComponent\[for a third-party\]{link="/developers/en/docs/mp-point/create-application#bookmark\_access\_credentials" linkText="Access credentials" content="Mercado Pago Point integrations to your system on behalf of a seller and configured using credentials obtained through the OAuth security protocol. For more information, access the link below."}) and making sure to send the value \`STANDALONE\` in the \`terminals.operating\_mode\` field. Confirm in the response that the change in operation mode was successful and restart your terminal to complete the process. ::: :::TabComponent{title="Terminal"} Press the \*\*More options\*\* button at the bottom of your terminal, choose the \*\*Settings\*\* option and then \*\*Linking mode\*\*. There, deactivate the \*\*Linked to point of sale\*\* option, and restart your terminal to complete the process. ::: :::TabComponent{title="Mercado Pago Panel"} Log into your \[Mercado Pago account\](https://www.mercadopago.com.ar/home), and access \*\*Your business\*\* in the left side menu. Access the \*\*Your Point terminals\*\* option, locate the terminal whose operation mode you want to modify and click on the three dots. There, select \*\*Unlink reader\*\*. To finish the process, restart your terminal. ::: :::: > NOTE > > Remember that this change should be temporary. You will need to \[return your terminal to PDV mode\](https://www.mercadopago.com.ar/developers/en/docs/mp-point/configure-terminal#:\~:text=mode%20on%20the-,terminal,-As%20the%20last) when the service is restored to maintain automatic reconciliation between your system and Mercado Pago and continue receiving your notifications. ::::: :::AccordionComponent{title="The order does not load automatically on the terminal"} If you created an order from your system and it is not automatically obtained by the terminal, it may be due to connection problems in your network. To solve this and be able to continue with the payment, you should press the \*\*Update\*\* button on your terminal, which will force the order to be obtained. This solution can also be useful for canceling it: if the order is not obtained by the terminal automatically, you can choose to :TagComponent{tag="API" text="cancel it via API" href="/developers/en/reference/in-person-payments/point/orders/cancel-order/post"}, or update your terminal and perform the \[cancellation\](https://www.mercadopago.com.ar/developers/en/docs/mp-point/payment-processing#:\~:text=Cancel%20an-,order,-An%20order%20can) through the reader. ::: :::::AccordionComponent{title="The API does not allow refunding an order"} If you are momentarily unable to perform a refund via API, and \[verified that you are meeting all the requirements to perform this operation\](https://www.mercadopago.com.ar/developers/en/docs/mp-point/payment-processing#:\~:text=Refund%20an-,order,-If%20you%20wish), it may be due to some unexpected interruption in our payment APIs. While we work to restore the service, you can perform refunds manually from your Mercado Pago Panel or from the same terminal. Choose the option that best suits your needs. ::::TabsComponent :::TabComponent{title="Terminal"} Press the \*\*More options\*\* button at the bottom of your terminal and choose the \*\*Activity with this Point\*\* option. There you can see the operations performed. You should select the operation you want to refund to access its \*\*Details\*\*. In this screen, scroll to the \*\*Related actions\*\* option, and select the \*\*Return money\*\* option. Finally, review the information to make sure you are refunding the desired transaction and confirm the action by pressing the \*\*Return\*\* button. The "Operation details" screen should now show you the refunded transaction with the status "Payment returned" and, going back to "More options", you can see this new activity with that terminal. ::: :::TabComponent{title="Mercado Pago Panel"} Log into your \[Mercado Pago account\](https://www.mercadopago.com.ar/home). On the main screen, you will see \*\*Your recent activity\*\*, with the operations performed. You should select the operation you want to refund to access its \*\*Details\*\*. In this screen, scroll to the \*\*Related actions\*\* option, and select the \*\*Return money\*\* option. Finally, review the information to make sure you are refunding the desired transaction and confirm the action by pressing the \*\*Return money\*\* button. You will see the confirmation of the operation and, if you press the \*\*Back to activity\*\* button, you will see the detail of the refund transaction. ::: :::: > NOTE > > To validate that the refund has been effective, whatever way you have performed it, verify that you have received a notification with the action \`order.refunded\`. ::::: :::AccordionComponent{title="The terminal does not print"} If you integrated the printing functionality and you are not able to get prints from your terminal, you must first make sure you have this option enabled. For this, contact our Support team and request its update. If your terminal already has the necessary update to perform printing, this functionality may be failing due to technical problems, such as insufficient paper roll or the coil has overheated. You should check the terminal warnings to be able to understand and solve the problem in each case. ::: :::AccordionComponent{title="Order status updates are not working correctly"} Verify that you have correctly configured \[notifications via Webhooks\](https://www.mercadopago.com.ar/developers/en/docs/mp-point/notifications) for the \*\*Order (Mercado Pago)\*\* topic. If you have configured any other topic, such as Payments or Point Integrations, you may be receiving alerts inconsistent with your integration. :::
