# Payment gateways > Connect your Cademí to the gateway where you sell, so each approved purchase gives the student access on its own. Pick your gateway and follow the steps. Connect your Cademí to the gateway where you sell: each approved purchase reaches Cademí and gives the student access on its own, and a cancellation or refund removes it. ## How the connection works The connection lives in a **delivery**, under **Sales > Deliveries**. In the delivery you pick the gateway, enter the identifier of the product you sell there and copy the **Postback URL**, the address the gateway uses to tell Cademí about each sale. In the gateway, you paste that URL into its webhook (or postback) settings and choose the events it sends. Once it is set up, the **Gateway connection** section of the delivery shows when the last sale arrived, or **No sale received yet**. ## Pick your gateway - [Abmex](https://help.cademi.cloud/en/vendas/gateways/abmex.md) -
