You can [get the data](https://docs.payvalida.com/api-recaudo/api-recaudo-en/purchase-orders/consult) of an order using our **API**, you can also [modify](https://docs.payvalida.com/api-recaudo/api-recaudo-en/purchase-orders/update) or [eliminate](https://docs.payvalida.com/api-recaudo/api-recaudo-en/purchase-orders/delete) it.
