License Key Constants

The constant for main Gravity Flow plugin is GRAVITY_FLOW_LICENSE_KEY

Each extension has a license key constant that allows the license to be set via code instead of the database:

GRAVITY_FLOW_FLOWCHART_LICENSE_KEY
GRAVITY_FLOW_PDF_LICENSE_KEY
GRAVITY_FLOW_CHECKLISTS_LICENSE_KEY
GRAVITY_FLOW_INCOMING_WEBHOOK_LICENSE_KEY
GRAVITY_FLOW_FOLDERS_LICENSE_KEY
GRAVITY_FLOW_WOOCOMMERCE_LICENSE_KEY
GRAVITY_FLOW_VACATION_LICENSE_KEY
GRAVITY_FLOW_STRIPE_LICENSE_KEY
GRAVITY_FLOW_PARENT_CHILD_LICENSE_KEY
GRAVITY_FLOW_FORM_CONNECTOR_LICENSE_KEY
GRAVITY_FLOW_PAYPAL_LICENSE_KEY

When the license key constant is set then the license key setting in the WordPress admin interface will be hidden.
If there are no other settings available on the settings page then the settings page for the extension will not be displayed.

For example, add the following line to your wp-config.php file:

define( 'GRAVITY_FLOW_FORM_CONNECTOR_LICENSE_KEY', 'your key' );

The constants require Gravity Flow 2.4.4 or newer.
