## Setting up at Secure Trading

If you wish to become a merchant and accept Secure Trading as a payment processor, register at [https://www.securetrading.com/](http://www.securetrading.com/). They should provide you with a Gateway Username, Gateway Password and Site Reference which is needed to setup Secure Trading with NATS.

You must setup the postback urls to which Secure Trading will post transactions to NATS (notification url):

*https\://\<linkdomain>/signup/process\_strading.php*

Please make sure to do the following when setting up the NATS notification url in Secure Trading's interface:

* *Do not return the field "maskedpan"*.
* *Add a custom field named, "passthrough"*.
* *Send all Requests, Payment types and Error codes.*

Ask Secure Trading to help you setup a redirect url to return members back to NATS for both approval and denial:

*https\://\<linkdomain>/signup/returnurl\_strading.php*

Next, they will need to add a custom field to the approval return url, "ok", and a different custom field, "failed", to the denial return ur&#x6C;*.*

Lastly, they need to replace \<linkdomain> with the linkdomain of your site.
