Linkpoint
Please don't test your biller setup with Linkpoint's test account—it won't work correctly.
Setting Up on Linkpoint's Website
Before you can begin configuring Linkpoint as a biller in NATS3, you must first register a merchant account with them. This can be done through their website at http://www.linkpoint.com/.
While registering with Linkpoint, make sure to take down the PEM File Location and Store Name/Number that were provided to you by Linkpoint. This information will be necessary for setting up Linkpoint API as a biller in NATS3.
Setting Up Linkpoint in NATS
Billers Admin
To begin setting up Linkpoint API as a biller in NATS, go to the Billers Admin. Scroll down to the "Biller" drop-down menu, select Linkpoint API, and click "Add."
Note: If you don't see Linkpoint API as a biller, put in a support ticket, as you may need an updated version of NATS.
When prompted, fill out your transaction and chargeback fees, along with when you wish to deduct them. Fill in your PEM File Location -- this is the location of the digital certificate that Linkpoint issued to you in their Welcome E-mail. Enter your Store Name/Number next -- this is your Linkpoint username and password.
Click Save once you have finished filling in the available fields on this page. Linkpoint API should now be configured and ready to process transactions as a biller in NATS3.
