NOTE: This feature is available as of version NATS 126.96.36.199
Token Plus is a feature in NATS4 that allows members of Token Sites to purchase additional tokens for their account, without requiring them to re-input their payment information. This lets your existing members complete additional token transactions quickly and easily, eliminating additional steps in the process.
To do this, you can give the following link to your users in order for them to purchase more tokens:
Enabling Token Plus
Before you can enable Token Plus in NATS, you must first have a Token Site set up in the Sites Admin. If you do not already have one, please see our Token Sites wiki article for more information on setting one up.
Once you have Token Sites set up in NATS, you can enable Token Plus by editing settings in the Sites Admin. To begin, navigate to the Sites Admin, locate the Token Site you want to enable Token Plus on, and click the "Set Join Options" action icon for that site. This will bring you to the "Join Options for this Site" page, where you'll see every join option that you have set up. Edit an existing join option, or create a new join option on which you want to have Token Plus enabled.
You will see a setting marked "Token Rebuy Allowed" -- check this box to enable the repurchasing of tokens by existing members. Once you have set that, configure the rest of your join option settings, and save your changes.
Token Plus will now be enabled for your chosen join option. You can enable Token Plus for any join option you set up for a token site in NATS. To do so, edit the join option for any site and check the "Token Rebuy Allowed" box.
You can also use rules to offer your Token Plus join option for a specific duration of time, letting you use it as a limited promotion. Please see our NATS4 Rules wiki article for more information on this feature.
Token Plus also contains additional security features, which allow you to further secure the transactions occurring on your join forms. For example, you can use API calls to get secure member authorization strings, verify surfer information on the join form, and change the input source to use POST instead of GET.
Use the MEMBER_STRING_AUTH_TOKENPLUS variable to choose whether or not you wish to use the new member auth strings available in NATS 4.1. These strings contain a variety of information, and are designed to prevent unwanted token purchasing attempts by outside sources.
This feature will be set to off by default. If you want to enable this feature for your Token Plus transactions, you can add the following necessary code to the config.php script on your NATS server:
$config['MEMBER_STRING_AUTH_TOKENPLUS'] = 1;
This will activate the MEMBER_STRING_AUTH_TOKENPLUS setting to use additional security for your member authorization strings. Do not add the provided code if you want to leave this feature disabled.
Once you have activated this setting, you must use the get_member_token_rebuy_string API call to get the correct auth string for the member you want to enable Token Plus for. Please see our NATS4 API Get Member Token Rebuy String wiki article for more information on this process.
This function will return the auth string that is required for your members to get authenticated for the Token Plus process. Include the auth string in the link for your member, and they will be able to use the Token Plus feature with the MEMBER_STRING_AUTH_TOKENPLUS security setting enabled.
Join Form Verification
The Token Plus feature verifies member e-mail addresses by default on the join form, but you can also add a switch to choose between verifying a member's e-mail address, password, or both e-mail address and password.
This feature will verify member e-mail addresses by default. If you want to enable this feature for your Token Plus transactions, you can add the necessary code in the config.php script on your NATS server:
$config['TOKENPLUS_REQUIRED_FIELDS'] = 1;
Add this setting with a value of '1' if you want Token Plus to verify member passwords. Change this to a value of '2' if you want Token Plus to verify both member passwords and e-mail addresses. Do not add the provided code if you want to keep authenticating member e-mail addresses.
This lets you choose what member information you want NATS to verify on the join form itself, preventing anyone from submitting a Token Plus join form with an incorrect e-mail address, password, or both.
Token Plus also offers another security feature, allowing you to change the method of submitting data from $_REQUEST to $_POST to further authenticate your members' information.
This feature is set to use $_REQUEST by default. If you wish to use $_POST to authenticate your join form transactions, add the following code to your config.php script:
$config['TOKENPLUS_POST_ONLY'] = 1;
Add this setting with a value of '1' if you want Token Plus to only allow $_POST when authenticating your members. If you want to use $_REQUEST when authenticating members, you do not have to add the provided code.
You can use the Throttling feature to help secure your tokenplus.php page, preventing surfers from forcing transactions without the correct auth string. Just go to the "Security" configuration page, found in the Configuration Admin.
For more information on this feature, please see our Throttling wiki article.
