Been awhile since there was activity on this one, figured I’d followup. I’d also like a way to apply my ACF key from the wp-config.php file. Recently been batch installing Let’s Encrypt SSL on my customer sites. Whenever there is a url change (like http:// to https://), ACF Pro drops the license and makes me reactivate. Having it applied from wp-config.php would solve this.
Another common scenario I run into is when I go from a development site to production (like newsite.wpengine.com to newsite.com). This also drops the license key and requires manually intervention to reapply.
