With web push notifications, you can stay in touch with your audiences even if they are not currently visiting your website. This article demonstrates how you can use the web push channel to reengage your contacts in case they abandoned products in their carts.


  1. Abandoned Cart: in order to use product details (such as image, URL, etc.) in Abandoned Cart campaigns, you need:
    1. regular (e.g. once per day) Product Catalog updates set up in Mapp Engage,
    2. working Mapp Acquire account, or Abandoned Cart set up via the related Data create Record API endpoint.
  2. Web Push:
    1. An active Firebase account.
    2. Web push activated on your website


A) Configure Abandoned Cart Add Events in Mapp Acquire

Detailed instructions are available in this online help article.

B) Set up Web Push Channel in Mapp Engage

  1. Go to Administration > Channels > Websites.
  2. Click Create Website Channel
  3. Give the channel a name.


    Mandatory, unique channel name, used to identify the website channel within the system and is not visible to your contacts.

    DescriptionOptional, also not visible to your contacts.
  4. Enter the FCM Credentials: the FCM Json Key. The following video shows how to generate the Key in Firebase. For more information see Firebase Cloud Messaging.

    If you didn't provide a FCM Json Key, or if you provided an invalid one, you won't be able to activate the channel upon the last step (Summary). Instead, you will only be able to Save the channel or Close the creation process. In case of a valid FCM API Key, you will be able to first Activate the channel before saving it and closing the process.

    Click Next.

  5. A Summary page gives you an overview of all of the previous steps.
