OpenWater now has a quick configuration option that will connect with your Stripe account to automatically pull the necessary information for your StripeJS with 3D Secure payment configuration. From your OpenWater dashboard, go to System Settings > Payment Configuration:

Then click the "Add New Payment Configuration" button:

Name your configuration appropriately, check the box to "Allow payment by credit card" along with any other options that fit your needs, then scroll down to the Select Merchant Account drop down menu. Once there, click and look for StripeJS with 3DSecure - Quick Config:

Once you've done that, click on the "Connect with OAuth" button which will take you to Stripe. Login with your Stripe credentials and select the Connect option once logged in:

After the connection is established you'll be taken back to your OpenWater payment configuration settings where you will see your connected account here:

Save and Test to confirm.
