Choose the API You Wish to Use:

Note that those two APIs are like oil and water; they DO NOT mix at all -- use one or another!


Simple API (Experimental)

Since 2019/04/15 we are removing the Simple API docs from the tabs on the Traditional API docs' pages. That docs-cohabitation concept did not work -- neither for docs nor for the users :(.

Until we are done with that documentation reorganization please make sure that your Simple API integration efforts start with one of the following four step-by-step integration guides:

Those four guides listed above are updated and polished and should be reasonably bug-free in this moment. If you find a bug, or would like to propose an improvement, please let us know.

The rest of the Simple API docs on both the old and the new locations are a fairly outdated mess -- and should not be relied upon until further notice!


Traditional API

Until the 2019/04/15 the Traditional API docs' pages were forced to host the tabs with their unruly, ever-changing, but rarely up-to-date, experimental Simple API cousins.

It did not work; both us and the users were getting lost -- so we are kicking the Simple API docs out to a new, separate, branch of documentation.

However, we might need a week or two to clean up all the mess that such a cohabitation created. If you spot a bug in the Traditional API docs please let us know.
