License and domains

A license is valid for an unlimited period of time on one single Magento installation

  • If you're using more than one Magento installation, you will have to buy a separate license for each instance.
  • if you're running several domains on a same Magento installation, you will need only one license for all of them.
Although your license doesn’t have a limited period of validity, your support period does. By purchasing an extension, you’ll be granted a 6-month support period for free. Passed this period, you will have to pay for a new one (see FAQ: Extend your Support period)

You can pre-register your live domain to your license in advance.

Thanks to this option, you'll be able to get the extension ready to use on your domain before it goes live.

  3. Click on the link at the bottom of the page saying:
    Do you want to pre-register your domain in order to be ready to go live?
  4. Finally, enter your domain name and click on pre-register now .
Attention, this doesn't mean your license is activated. You'll still have to activate it on your new domain when the extension is installed. 

One license is valid for an unlimited period of time on one Magento installation only. However, it is possible to extend or transfer your license in 2 cases: 

  • If you would like to add your testing environments to your license. 
    In that case, it is possible to extend your license to an unlimited number of domains for free.
    For example: or
  • If you want to transfer your license to another live domain.
    In that case, the support period for your license must still be active.

    1. Go to your Magento admin panel. A message pops up at the top of the page.

      If the message doesn't appear then you must check that:

         1. The Adminhtml_Notifications and Wyomind_Core modules are well enabled.
         2. The HTML output of the Adminhtml_Notifications and Wyomind_Core modules are not disabled in:
      storesconfigurationadvanced advanced
         3. The encryption key well exists in app/etc/env.php:
       return array(
       'backend' => array(
       'frontName' => 'admin'
       'crypt' => array(
       'key' => '1e8f3c6772b7a6a6689c3c8cefa4ccf0'
       /* ... */
    2. Copy your activation key in:
      StoresConfigurationWyomind Your extension

      You can find your activation key in 2 different places:

      By choosing No, you will have to log on to Wyomind license server yourself.

    4. Click on Save config .
    5. A message appears at the top of your admin panel. Click on that link: 
      Activate it now!
    6. Copy and paste the license code in the License code field from your admin or simply click on Activate now! 

    7. Finally, refresh your cache, log out and log in back straight after, to complete the installation.

When the extension includes other modules, repeat the steps described above for each one, using the corresponding activation keys (each module has its own activation key).

Add another domain to your license

To activate the license on another domain (test, staging...):

  1. Once the extension is installed on the new domain, copy your activation key in:
    StoresConfigurationWyomind Your extension
  2. After having saved the configuration, a notification appears. Click on Add this domain to my license.

  3. A transfer request will then be sent to our team within an hour.
    Once the request is taken care of, you will receive a confirmation email.
    If your transfer request is accepted, you can use MSI Custom Attributes on both environments at the same time.

Note that the order in which you activate your license on your domains does not matter. You can start with your staging/dev/local environment or with your live domain, the process will be the same.

Also, if you have loads of staging domains, or if you are an agency managing load of domains for your customers, please contact us so that we can automatically whitelist these domains.

Once MSI Custom Attributes is installed, you have to activate the license.

For this, you can use the below command line (change the Activation key with the corresponding value):

bin/magento wyomind:license:activate Wyomind_MsiCustomAttributes <YOUR_ACTIVATION_KEY>

To retrieve the list of all the available modules as well as the licenses status, please use:

bin/magento wyomind:license:status

 Among the different status, you can find: 

  • registered = your license is registered
  • pending = you need to run the activation command line
  • invalidated = the license has been invalidated due to a wrong activation key or a license infringement
Check how to add another domain to your license.
