Migration from an existing plugin

Important for existing customers or users who already use the existing plugin (heidelpay/magento2 or heidelpay/magento2-merchant-gateway).

For users who already use the existing plugin, it is necessary for a transitional period to include both store plugins in parallel in the store and to leave the old one configured and active. The new plugin cannot reference old orders/transactions.

Therefore, you should preferably activate the required payment types in the new plugin and deactivate the corresponding payment types in the old plugin. The old plugin must continue to be configured and activated for the old orders placed via it in order to continue to ensure the payment processing of existing orders (for example, for a return or refund).

Step 1: Install the plugin via Composer

1. Install the Plugin using Composer.

   Install using Composer

   ```text
   composer require unzerdev/magento2
   ```
   

2. Once Composer has installed the dependencies and the plugin, activate it using the following command: php bin/magento module:enable Unzer_PAPI --clear-static-content

3. Run the setup:upgrade command through the console, to import the plugin schema into your database:
   php bin/magento setup:upgrade

4. The following commands clear the cache and execute the final steps for plugin installation— the generation of dependency injection and deployment of static files for the front end. php bin/magento cache:flush
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy

The installation is now complete, and you can configure the plugin in the admin back end.

Step 2: Configure your plugin environment

In the store backend, go to Stores > Configuration.

1. Select Sales > Payment Methods.
2. To configure the store view, select the level that you want to configure in the top left corner. Normally, you can configure settings for the module in the Default Config. This means that the key pair configured here is used for all store views.

Alternatively, you can configure different key pairs for each store view.

General Settings

Select Unzer Merchant Gateway (MGW) and select Settings to update the general setup details like your key pair.

Available parameters

Save the configuration before you register the webhook events so that the correct key pair is used.
