Does Google Custom Search Engine require a third-party add-on to integrate with ExpressionEngine?
ExpressionEngine v2.5.0 - Build Date: 20120507
Thank you for posting your question here on the ExpressionEngine forums.
I am not aware of any needed plugin. There is an Add-On that works with Custom Search.
I will move this over to the Community Help Forum where someone who has set this up before should be able to give you some more direction.
