Check marketing UTMs used at Checkout

When the utm_source, utm_campaign or utm_medium parameters are used to load a store page, the system creates a cookie named IPS whose value is equal to the value of the parameter.

The orderForm of orders closed by the user will receive this cookie in the header of the request sent to Checkout (until this cookie expires). In other words, the moment the customer clicks the Buy button, the buy button native control (<vtex.cmc:BuyButton/>) will perform a POST request to send the value of the utm_source parameter to the Checkout.

In this way, the Checkout will be able to assemble the orderForm considering the marketingData used in the purchase.

To make sure the content of the utm_source parameter is being sent to the Checkout, you can follow the steps below:

  1. Access any page of the store with the utm in the querystring (e.g. {AccountName}.com.br?utm_source=facebook).
  2. Enter the Developer tools (F12 in Chrome, if you are in Windows, or Cmd+Opt+I on a Mac)
  3. Go to the Application tab.
  4. Open the store's website cookies and look for the IPS cookie.

The presence of the utmSource field with the same value as utm_source means that the information was correctly received by Checkout. If the utmSource` field was empty in the orderForm, it would indicate that the value was not sent to the Checkout.

📘

When the value is not sent to the Checkout, any benefits linked to the utm_source will not be applied to the orders, and OMS will not register these UTMs as order parameters.

Why are the UTMs not being applied to the cart?

One of the most common reasons the marketing context is not sent to the Checkout is the customization of the purchase call.

As previously stated, the native buy button control (<vtex.cmc:BuyButton/>) performs a POST request sending all the data needed to the Checkout, including the value of the utm_source, utm_campaign and utm_medium.

However, if instead of using this control, your store decides to customize the call and therefore makes the POST of the purchase request on its own, you must remember to send in this POST all the data that may be useful to assemble the orderForm, including the marketing context.

To send the UTM values ​​to the cart, access the Add marketing data endpoint or enter the marketingData information via the sendAttachment.
