NATS4 Additional Tracking
Feature Summary
In NATS 4.1 (version 4.1.7.1 and above), you have the ability to allow your affiliates to add additional passthrough variables in their linkcodes that will get stored with a member's subscription record. These variables become available on postbacks. In addition to these passthroughs, methods for forcing the join option to be used on the join form and changing the default join option have also been added.
These additional tracking features can only be used if you allow them within their "Edit Affiliate Admin Settings" page. The two settings are called "Subscription Passthrough Variables in Linkcodes", and "Force Join Option in Linkcodes". Once you enable the feature for their account, they can add a "nats_at" array with the additional variables to the end of a link code.
Join Option Variables
You can force a specific join option on the join form by passing the following variable in the URL:
nats_at[force_optionid]
You can change the default join option on the join form by passing a similar variable:
nats_at[default_optionid]
Subscription Passthrough Variables
You can add up to 5 additional subscription passthrough variables that will get stored with a member's subscription
nats_at[subscription_passthrough1] nats_at[subscription_passthrough2] nats_at[subscription_passthrough3] nats_at[subscription_passthrough4] nats_at[subscription_passthrough5]
Keeping these variables in the URL after redirect
By default, the nats_at array will not available in the URL after the tracking redirect. It is still stored with the subscription and will become available on postbacks. You can control this behavior with the configuration "REMOVE_EXTRA_QUERY_TRACKING_VARS" which can be found in the "Surfer" section of the configuration admin.
Additional Parameters
If you need to ensure that any existing passthroughs are not used and are overwritten ( passthroughs are stored based on the IP & session), add the following parameter to the track link: nats_at[clear_existing_values]=1
Additional Notes
Example link:
http://<linkdomain>/track/<nats_code>/?nats_at[force_optionid]=<optionid>&nats_at[default_optionid]=<optionid>&nats_at[subscription_passthrough1]=<custom passthrough1>&nats_at[subscription_passthrough2]=<custom passthrough2>
The tracking is site specific. Going through a link code resets it.
