## Setting Up at RSBilling Native

Before you can begin setting up RSBilling Native to handle transactions in NATS, you must first sign up for an RSBilling Native account. You can do this on River Styx Internet's website, located at [https://www.sentrypayments.com](http://www.sentrypayments.com/)

Please make sure that your server is allowed to access the domain secure.sentrypayments.com by River Styx Internet so that your NATS installation will get the most up to date IP address list.

## Setting Up RSBilling Native in NATS

### Billers Admin

To begin setting up RSBilling Native in NATS, go to the [Billers Admin](/nats-admin/billers.md), scroll down to the "Setup New Biller" drop-down menu, and choose "RSBNative" from the list of available options.

When prompted, fill in your RSBNative Merchant ID, and Merchant Password. You can also fill out the optional Transaction Server and Reporting Server fields here. All of this information must be obtained directly from RSBilling. If you do not have this information, please contact your biller to get the required information. Click Save when you have filled out the required fields.

### Sites Admin

Next, go to the [Sites Admin ](/nats-admin/sites.md)to continue configuring RSBilling Native in NATS. Create a new tour, or edit an already existing tour to use RSBilling Native with. On the next page, scroll down to the "Biller Details" section and enter your Site ID in the field marked, "RSBNATIVE Site ID."

Once you have done that, scroll down to the "Join Options for this Tour" section, and edit the join options you want RSBilling Native to process transactions with. On the next page, enter your Schedule ID in the field labeled, "RSBNATIVE Schedule ID" and click Save.
