Hello Rocco !

Not sure that I've got your idea, but if you don't want to use in Froala the same embedly key like you set in the Studio->Settings->General area then you may to correct it in the next place of modules/boonex/froala/classes/BxFroalaEditor.php file:

'bx_var_embedly_key' => bx_js_string(getParam('sys_embedly_api_key'), BX_ESCAPE_STR_APOS),
