Step 1

Purchase the extension on the magento marketplace. Don’t worry the extension is free and you won’t need any payment details. You can find the extension here - https://marketplace.magento.com/metrilo-analytics-magento2-extension.html

In order to make the purchase you will need an account on the Marketplace.

Step 2

In your Magento 2 installation folder run the following command:

composer require metrilo/analytics-magento2-extension

If all went well you will see something like:

In case you get asked for authentication:

Use the access keys from the marketplace profile you used in Step 1. They keys can be found on this page: https://marketplace.magento.com/customer/accessKeys/

The public key is the username
The private key is the password

In case you get a message about missing extension:

Make sure that you are using the correct credentials for authenticating in the marketplace. The credentials are sometimes cached in a file called auth.json in the project root or in the user root directory ~/.composer/auth.json.

Step 3

Now that the plugin is successfully installed run:

$ bin/magento setup:upgrade

Step 4

Configure the plugin by going to "Store" > "Configuration" > "Metrilo" > click "Analytics".

You can take the credentials from the Settings/Installation page of your Metrilo project.

Step 5

Clear any caches you might have to make sure that the metrilo code appears on all of your pages.

$ bin/magento cache:flush
