# How to obtain the necessary values ​​for AdCombo COD form presells

The **COD with Form** pre-sell for AdCombo asks for four values that live in your network panel. This article shows where each one is.

## API key

Click your name in the top right corner and choose **Account settings**.

On the **Security** tab, the **API key** is hidden. Click the eye to reveal it.

With the key visible, copy it using the button next to it.

> ${color}[#7C3AED](Treat this key like a password.) It gives access to your account on the network — never share it.

## Campaign code

Go to **Offers** and open the offer you promote. The campaign code is the **ID** shown right below its name.

## Offer country

It is in the offer name itself: in **Magicoa – MX**, the country is Mexico. Each AdCombo offer belongs to one country, and it is against that country that the network checks the buyer's phone — which is why the form asks for it.

## Affiliate link

On the same offer page, scroll to **Tracking URL** and copy the link with the button on the right. That link is what takes the visitor to the offer after the order.

## Amount with currency

This is the price the buyer sees on the page, in the format of the offer's country — for example `890 MXN` for Mexico. Use the same price shown on the offer's landing page, so the visitor doesn't run into a different amount later.

## Where these values go

In AdsX, go to **Products**, click **Start** on the product row, then **Create presell**, pick **COD with Form** and then **AdCombo**. The form asks, in this order: **API Token** (the key), **Campaign Code** (the offer ID), **Offer country**, **Your Affiliate Link** and **Amount with currency**.

## Tips

* **Changed your API key on AdCombo?** Create the pre-sell again. A published page keeps the details it was created with.
* **The campaign code only accepts numbers.** It is the offer ID, not its name.
* **The phone must match the offer country.** A number from another country is rejected by AdCombo when the order is placed.
