How to Activate WP SMS Licenses from wp-config.php

From version 7.0.1 onwards, you can activate your licenses directly from the wp-config.php file. This feature is especially helpful for users who need to activate licenses on multiple sites and prefer simply copying and pasting a code snippet rather than manually entering license keys for each add-on on each site, whether on a multisite network or individual WordPress installations.

How to Add License Keys to wp-config.php

1. Open wp-config.php for editing.

2. Find a suitable location, ideally towards the end of the file, above the line that says /* That's all, stop editing! Happy publishing. */.

3. Add the license keys by defining the WP_SMS_LICENSE constant:

For multiple add-ons (if you have licenses for more than one add-on), define the keys as an array:

 define('WP_SMS_LICENSE', [
 	'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
 	'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
 	'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
 ]);

Or, you can define them as a comma-separated string:

define('WP_SMS_LICENSE', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx,xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx,xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');

For a single license (e.g., WP SMS All-in-One or a single add-on), define it as a single string:

define('WP_SMS_LICENSE', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');

4. Save the changes to the wp-config.php file.

5. Visit your site and go to SMS → Add-Ons to confirm that licenses have been activated.
