Connex works with Magento 1 and 2.
If I have Magento 1.x, how do I upgrade to Magento 2?
Magento 2 and Magento 1 are completely different. You must install Connex from scratch. Login to Connex. Click add a new connection. Choose Magento 2 and enter your admin user name with password. Complete the install wizard.
If you would like us to transfer your Magento 1 settings to the Magento 2 connection, please contact us.
Does Connex send my Magento credentials, each time it request orders?
With your Magento user name and password, Connex generates a token valid for four hours. The token is sent to your site and it returns orders. For more technical details, read admin and customer access tokens.
How do I pair Magento 2?
You must enter your admin login, password, and URL on the Connex my connections page. Connex will receive a special token from your website, then remove the user name password from our database:
Does the Magento 1 and 2 integrations support the same features?
Yes, whatever you can do with Magento 1 you can do with Magento 2.
