While you may post to ClickaPost almost without using any of the Get Methods (except for the main <category> you are posting into), in order to fully maximize your classifieds your posts will definitely benefit if you enter more data.
Some of the fields like: <duration>, <showPriceType>, <country>, <stateProvince>, <city>, <keywords>, and <embeddedVideos> require you to have some specific knowledge and unique ID’s assigned to these items in order to associate them with your posts correctly.
In order to get this information, ClickaPost's API can respond back to you if you use the our "Get Methods".
