Create a field-mapping/mergefield in the audience First you have to create it on Mailchimp and then you will see it on Magento (once you configure an API Key). By clicking in "add" in Magento, then you will see two columns, first one references to Mailchimp and the second one references to Magento, they have to be the same. In the left is the customer info and in the right is the value it will assign it. In this case we will use date of birth ![]() Other things to consider: a. Cronjobs: Mailchimp for Magento 2 requires the Magento cron to be set up an running, without this the extension can't work because it relies on this to synchronize data. See more at: http://devdocs.magento.com/guides/v2.2/config-guide/cli/config-cli-subcommands-cron.html b. Syncing from Mailchimp to Magento: Even though the main function of the extension is to sync data to Mailchimp, you can also sync subscriber information from Mailchimp to Magento. This on top of requiring a cronjob task to run, it requires a webhook for your configured list so that Mailchimp can communicate with your site when it has updated information for the subscribers. If the webook wasn't automatically created for your Mailchimp list (you can check this on your Mailchimp account, going to your list, then to Settings>Webhooks), you can create it on the Mailchimp extension settings in Magento using the "Create Webhook" button that appears when you enable 2-way sync. You need version 1.0.28 or higher to have this available. c. Domains and multistore: Have in mind that as of recently, Mailchimp has made some modifications to the API, and now each store you have connected to Mailchimp must have its own domain. Meaning that if you have a multistore Magento where the extension is configured either at the website or storeview level for multiple-stores, each store must have its own domain in one of the following ways, even if the only difference is the language. Format: Store 1: en.store.com Store 2: es.store.com Read the following article (Step 6) on how to add a store code: http://devdocs.magento.com/guides/v2.0/config-guide/multi-site/ms_websites.html |
