> Connect Lia to your Cademí: the product ID in a one-time sale delivery and the integration under Ferramentas > Cademí, where you paste the Postback URL.

Connect Lia to your Cademí so each approved purchase gives the student access on its own. You need the product ID and Lia's **Cademí** integration, where you paste the Postback URL. Lia does not ask for a token.

## 1. Create the delivery in Cademí

1. In the Cademí dashboard, open **Sales > Deliveries** and add a delivery.
2. In **Select a Gateway**, pick **Lia**.
3. In **Delivery Name**, enter a name that helps you recognize it later.
4. **Sales Mode** shows only **One-time sale**: a Lia delivery has no **Subscription** option.
5. The **Gateway connection** section shows the **Product ID** field and the **Postback URL**.

Keep the delivery open: you come back to it in the next steps.

## 2. Find the product ID

1. In Lia, open **Ferramentas > Cademí** (Tools > Cademí) in the side menu.
2. Select the product you deliver through Cademí.
3. Copy the **ID do produto** (product ID) shown on the screen and paste it into **Product ID** in the Cademí delivery.

## 3. Set up the integration

1. Still under **Ferramentas > Cademí**, paste the **Postback URL** of the delivery into **URL de postback** (postback URL).
2. Click **Salvar** (Save) and, in Cademí, save the delivery.

**One product at a time:** the Lia integration is set per product. Whenever you create a new product on Lia and want to deliver it through Cademí, repeat steps 2 and 3.
