Setting up MarfeelPass

Integrating MarfeelPass in your site is a hassle free process that takes a few minutes:

  1. Upload Marfeel’s ApplePay merchant file to allow Marfeel process payments on your domains.
  2. Create a no-code MarfeelPass experience for your web version. Start easy and frictionless simply adding a MarfeelPass button on your existing CMP notice popup without the need of development resources.
  3. Create a MarfeelPass Notice CMP experience for your web version. To prevent visual flickers and have a complete user experience disable your CMP’s notice popup so MarfeelPass becomes the UI to your CMP.
  4. Enable the MarfeelPass Notice CMP experience in AMP. Once the MarfeelPass CMP notice popup is setup on the web version you can enable it on your AMP pages seamlessly.
  5. Whitelist your domains to successfully accept payments

1. Upload Apple Pay merchant file

Apple Pay Merchant is a service that allows businesses and developers to accept payments within their apps and websites using Apple Pay. To authorize Apple Pay payments, the MerchantId associated with the Marfeel Developer needs to be uploaded to a specific server location. This process ensures the proper configuration for accepting Apple Pay transactions and enables a seamless payment experience for users.

Upload the Marfeel MerchantId file apple-developer-merchantid-domain-association (8.9 KB) to this server location

Don’t change any part of the location. Upload it to the root of your domain indicated as in the example above.

If you have multiple subdomains you need to upload the merchant file to each of them individually.

2. Create a Marfeel CMP No Code experience

For quick experimentation and testing, MarfeelPass provides a no-code configuration mode. This mode operates by manipulating the Didomi notice HTML in the DOM, adding or removing action buttons as needed. Keep in mind that using the no-code layout might cause visual flickers and could break if there are changes to Didomi notice CSS selectors.

We strongly recommend implementing the Web Native Integration to disable the default CMP notice, as explained below. The no-code experience should only be used during trials or proof of concepts.

Follow the steps below to create a no-code Marfeel Experience:

  1. Go to Experience Manager
  2. Click on Create Experience
  3. Choose MarfeelPass from the popup’s side bar
  4. Create a MarfeelPass CMP No Code experience

In the Content tab of the experience you’ll be able to set up:

  1. Amount to charge users to reject consent
  2. Reject button text
  3. If rejection payment should be shared across subdomains or not

3. Create a MarfeelPass CMP Notice Experience

Once you’ve easily tested MarfeelPass via no code it’s strongly recommended that you replace your CMP notice popup with a MarfeelPass notice. Doing so will:

  1. Allow MarfeelPass to show itself anytime users change the CMP configuration and completely or selectively reject a Purpose.
  2. Prevent visual flickers when adding the MarfeelPass button in the DOM

MarfeelPass only replaces the UI notice from your CMP. MarfeelPass delegates on the underlying CMP the consent management using generic TCF or vendor specific APIs.

Follow these steps below to create a MarfeelPass CMP Notice Experience:

  1. Go to Experience Manager
  2. Click on Create Experience
  3. Choose MarfeelPass from the popup’s side bar
  4. Create a MarfeelPass CMP Notice experience

3.1 Choose a Layout

Once created choose one of the two out-of-the-box responsive layouts MarfeelPass offers:

Customize all texts and call-to-actions according to your preferences and specific legal needs in your country. Choose between a favicon style or the full brand logo, and even create a custom layout.

3.1.1 MarfeelPass experience parameters

  1. Layout: choose the layout that better fits your strategy
  2. Country:
  3. Currency: The currency of the payment. Valid currencies are EUR or USD
  4. Amount: the price to charge users for 24h. Use a . to specify cents. Valid prices are 50 or 0.50
  5. Share payment across subdomains: Configures if rejection payment should be shared across subdomains or not

3.1.2 Visual Configuration

Use generic Experiences styles’:

  1. Primary color: To change the color of the call-to-actions
  2. Icon: To add an icon or the full brand logo

3.1.3 Targeting

You can have different MarfeelPass experiences impacting different users depending on some conditions. As the experience needs to use Pre-Targeting phase, dimensions available are limited to the following:

  • Host
  • Folder
  • URL
  • HTML Language
  • Browser Language
  • Experiment Groups - select “Custom Variable” and enter the name of the experiment group, which you need to have previously configured in Experiences Settings.

4. Configure MarfeelPass as your CMP notice

4.1 Didomi integration

Disable Didomi notice by default. This will prevent showing Didomi’s consent layer so MarfeelPass layer can show.

The code below must be added above Didomi’s initialization code:

<script type="text/javascript">
   if (!window.didomiConfig) {
      window.didomiConfig = {};
   if (!window.didomiConfig.notice) {
      window.didomiConfig.notice = {};
   if (! { = {};

   // time in seconds pay to reject should be valid. In this example, one day in seconds is 24h * 60min * 60s = 86400. = 86400; 
   window.didomiConfig.notice.enable = false;

Connector Details

MarfeelPass relies the following Didomi specific methods:

  1. MarfeelPass CMP notice will show when TCF API notifies there’s no valid consent string
  2. Accept all: Didomi.setUserAgreeToAll()
  3. Reject when payment successful: Didomi.setUserDisagreeToAll();
  4. List of partners: Didomi.getRequiredVendors()
  5. Open vendors list:'vendors')

5. Configuring AMP

Following the same strategy for the Web integration the MarfeelPass notice is displayed to the users instead of using Didomi’s default one.

Make sure to replace the experience id `{{EXPERIENCE_ID}}` with the one from your experience. Also add the promptUISrc, sandbox and uiConfig properties as shown below.
<amp-consent id="consent" layout="nodisplay" type="didomi">
  <script type="application/json">
      "promptUISrc": "{{EXPERIENCE_ID}}&type=amp&canonical_url=CANONICAL_URL",
      "sandbox": "allow-top-navigation-by-user-activation allow-popups-to-escape-sandbox",
      "uiConfig": { "overlay": true },
      "clientConfig": {
         "config": {
            "notice": {
               "initialHeight": "70vh"
             "app": {
                "apiKey": "XXX" //Your API key
         //... Any other custom clientConfig you might have

You can get your experience promptUISrc from Experience Manager:

Note that the promptUISrc property has canonical_url=CANONICAL_URL. You can add or remove this parameter in order to enable or disable the redirections to the canonical when payment mechanisms are not available. If the canonical_url param is not provided MarfeelPass will fallback to a simple Reject All option.


In order to properly track CMP metrics and private sessions on AMP please make sure to use AMP tracker v.2.0.

6. Whitelist your domains to successfully process payments

Before enabling MarfeelPass in production ask Marfeel Support team or your Account Manager to whitelist your domains in order to successfully process payments on them.

7. Review your site configuration

1. Ensure Marfeel SDK Priority

2. Disable Interaction-Blocking JavaScript Code

  • Check for any JavaScript code on your site that creates an interaction-blocking layer. It is essential to disable such code, as MarfeelPass manages this functionality directly.
