Please don't test your biller setup with Jettis's test account—it won't work correctly.
Setting Up on Jettis's Website
While registering with Jettis, make sure to take down the Merchant ID, Login, Password, and Terms URL that they provide for you. When you create a product with Jettis, make sure to record its Product ID. This information will be necessary for setting up Jettis in NATS3.
Setting Up Jettis in NATS
When prompted, fill out your transaction and chargeback fees, along with when you wish to deduct them. Fill in the Merchant ID, Username (login), and Password that were provided to you by Jettis under the "Account Info" section. If you were not provided with this information, please contact your biller to receive it.
Next, go to the Sites Admin, create or edit a site, and scroll down to the "Biller Details" section. Find the "Jettis" settings and enter a URL to your Terms and Conditions statement in the "Terms URL" field. This should match the URL that you provided to Jettis when registering.
Once you have done that, scroll down to the "Join Options this Site Offers" section and create or edit a join option to add Jettis compatibility. Under "Biller Codes for this Join Option," enter the Jettis Product ID for every join option you have set up with Jettis.
Click Save once you have finished filling out the available fields on this page. Jettis will now be configured and ready to process transactions in NATS3.
