# How to set up the AdCombo postback in AdsX

The postback is the link that tells AdsX about each AdCombo sale. Once it is set up, every AdCombo sale shows up in **My Sales** in AdsX, along with the ad that drove it. You set it up once for each AdCombo account.

## 1. Copy the postback in AdsX

In the side menu, open **Advanced Tracking → Activate Platforms**. On the **AdCombo** card, click **Copy postback**.

## 2. Open the AdCombo postbacks

Log in to the [AdCombo dashboard](https://adcombo.com/?ref_id=2b1e0fe0b065324c2bc70ca80039a589). In your AdCombo account, click **Postbacks** in the side menu.

## 3. Fill in the postback

1. Click the **Settings** tab.
2. **Postback URL for leads:** paste the postback you copied in AdsX.
3. Check **I want to use only global postbacks**.
4. Click **Save**.

## 4. Activate AdCombo in AdsX

Go back to AdsX and, on the **AdCombo** card, click **Activate**. Without this click, AdCombo is not active in AdsX.

The card now shows **Activated**, and AdCombo appears as an option when you create a presell.

## How to know it worked

The next AdCombo sale shows up in **Advanced Tracking → My Sales**. If it does not, check:

- that **I want to use only global postbacks** is checked;
- that the link in **Postback URL for leads** matches the one you copied in AdsX, complete and with no space at the end;
- that the presell product is from AdCombo.
