To receive the data, a well formed XML file is expected by the server. While most of the variables are OPTIONAL some of them are always required and besides a well formed XML file – two are essential.

ClickaPost API is implemented as vanilla XML over HTTP using raw XML (see sending via curl), or via either POST or GET (in which case you want to send your XML data in a variable with a name of "xml").

The XML request file must contain 2 nodes within the “request” branch:

• <auth> - used to specify the main authentication info for posting to server
• <posts> - where all post details are sent in between <post></post> tags.

Unique 64bit <token> tag is required under <auth> to properly identify the user who is posting. Users can generate this token and manage it in ClickaPost API section under My ClickaPost module.
