A hammer, chisel, file, rasp — all humble tools. In the hand of a master like Antoni Gaudí though, they are the instruments used to create a world wonder.

Just like these crafting instruments, the API is the tool providing developers with the opportunity to reshape our digital world. It is the tool that is forming online wonders that will bring about the next phase of the digital economy — the great connection. It is an exciting time to be working with APIs.

Just as for the master Spanish sculpture, continuous learning is essential. It is critical that your API skills and knowledge do not become outdated, an easy outcome given the fast moving environment we find ourselves in.

This is why I felt it would be useful to bring together some of the best online API learning resources. Don’t hesitate to add your own favorites in a comment or on our Facebook page.
