A common question we receive is asking whether a merchant can integrate multiple websites into their Green account. The simple answer is, Yes!
This is not a problem at all. While we only have one website listed in a Green account as the primary website on file, this listing has no bearing on the API itself. If you would like to install a green plugin or integration on various websites, all you need to do is install them as you normally would per their instructions and use the same API Credentials (Client ID and ApiPassword values) on each integration.
All checks entered using an integration with those API Credentials will enter into that same account.
