I want to set the template variable in Magento RMA email template using observer or plugin. Unlike in email order (i.e. email_order_set_template_vars_before) or email shipment (i.e. email_shipment_set_template_vars_before), default Magento's RMA doesn't have custom event for passing template variable. So, anyone has idea regarding that.

Thanks in advance !!!

To add a custom template variable in the email template for Magento RMA in Magento 2 Enterprise, you can use a plugin to modify the Magento\Rma\Model\Rma class.

Here are the steps to add a template variable in the email template for Magento RMA:

  1. Create a module and define the plugin in the module's di.xml file:

    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
      <type name="Magento\Rma\Model\Rma">
          <plugin name="add_custom_template_variable" type="Vendor\Module\Plugin\RmaPlugin" />
  2. Create the plugin class RmaPlugin and add the template variable in the beforeSendEmail method:

     namespace Vendor\Module\Plugin;
     use Magento\Rma\Model\Rma;
     class RmaPlugin
         public function beforeSendEmail(Rma $subject, $templateVars, $area, $store)
             $templateVars['custom_variable'] = 'Custom Value';
             return [$templateVars, $area, $store];

In this example, the template variable $custom_variable is added with the value Custom Value.

  1. Use the template variable in the email template for Magento RMA by adding the variable inside the curly braces:


That's it! Now you can use the custom template variable in the email template for Magento RMA.

  • Hello Navneet, In the RMA module, there is no file like this Magento\Rma\Block\Adminhtml\Rma\View Mar 16, 2023 at 11:00
  • Are you using Magento EE or CE? If you are using CE, then you must have installed a third-party module, because Magento EE has a built-in module. Mar 16, 2023 at 11:55
  • I am using Magento EE only Mar 16, 2023 at 12:01
  • I have updated my answer can you try with that Mar 16, 2023 at 13:00
  • I have checked the core magento rma module and I don't find the function sendEmail in given plugin !!! Mar 16, 2023 at 14:14
