Extra Biller Fields
Some billers have hundreds or thousands of modifiable options on their join form. NATS lets you modify these extra features, which we call Nextra features, by adding the nextra field to the NATS pre-join form.
You can use the Nextra feature by adding the keyword nextra to any HTML name field, followed by the biller's shortname and the special value in brackets. In short: nextra[Biller Shortname][Special Value]. For example, you can send the special value "date" to CCBill using any of the following examples:
- <input type="hidden" name="nextra[CCBILL][date]" value="2006-06-11">
- <input type="text" name="nextra[CCBILL][date]">
- <textarea name="nextra[CCBILL][date]" cols="10" rows="10"></textarea>
If you want to send the same special value to NetBilling, you need to add a nextra command. For example: [NetBilling][date].
(Note: You can get the biller's shortname using the Billers Admin; click on the biller's name and find its shortname option.)
