Which of the following are methods of data capture?

APIs (Application Programming Interfaces) allow different software systems to communicate and exchange data, making them a common method for automated data capture. Tags, such as tracking pixels or JavaScript snippets embedded on websites, collect user interaction data and send it to analytics platforms. FTP (File Transfer Protocol) is used to transfer files, including data files, between computers over a network, enabling bulk data capture and transfer. CDG is not a recognized standard method for data capture; it might refer to various unrelated concepts or be a made-up acronym in this context.
