API - application program interface. Related Terms. Application program interface (API) is a set of routines, protocols, and tools for building software applications.

By Rowena Pedrena. A traditional golf set has 13 clubs: three woods, nine irons (including three wedges) and one putter. The USGA limits the number of clubs a player may carry in his or her bag to 14. A player may include an additional wedge or wood to a fill a gap in hitting distance.
At a minimum, you should carry a set of irons that runs from 6 through PW, which counts for five more clubs. At this point, there are eight clubs in your bag, and there should be no doubt that those clubs are safe. That leaves you with six spots available to be filled.
