i wish to make an wordpress wordpress plugin, and also to place it public, however i want that just the customers which have a particular unique code to have the ability to activate it.

can there be possible while using wordpress api to request for any unique code at wordpress plugin activation (and also to condition the wordpress plugin activation with this code)? I looked wordpress codex, but nothing found.

thanks!

This seems like that old akismet wordpress plugin which needed customers to join up to have an API token. You are able to in your wordpress plugin require customers to go in configurations and at this time prompt these to sign up for an API key.

Begin to see the WordPress codex for adding an options page. Also see this example for among connecting in to the wordpress plugin activation:
