# How to obtain the necessary values for Traffic Light COD form presells

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

## API key

In the Traffic Light panel, click your name in the top right corner and choose **Profile**.

Open the **API** tab and copy **Your API KEY** using the button on the right.

> ${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 find the offer you promote. The campaign code is the **number** shown before its name.

> ${color}[#d9534f](Careful: it is the number, not the stream code.) The stream has a code with letters (for example `RnwTbzKJ`), and it does not work in this field.

## Affiliate link

Still on the offer, click **Create a stream** (or open a stream you already have) and copy the **HTTPS link**. 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 country you advertise in — for example `790 MXN` for Mexico. Use the same price as the offer, so the visitor doesn't run into a different amount later.

## Where these values go

On the form, fill in **API Token** (the key), **Campaign Code** (the offer number), **Your Affiliate Link** and **Amount with currency**. Then click **Create presell** and choose the domain and the page address. The page shows up under **Created pages**.

## Tips

* **The product image already comes with the page.** It starts with a drawing in place of the photo; swap it for the real one in the visual editor, under **Created pages**.
* **Changed your API key on Traffic Light?** Create the pre-sell again. A published page keeps the details it was created with.
* **The campaign code only accepts numbers.** If you paste the stream code, AdsX warns you right away.
* **Advertise the pre-sell link**, not the affiliate link directly: it is the pre-sell that captures the order and sends the visitor to the offer.
