Note :The XML-RPC APIs are deprecated (but
functional) now. We requests partners and users to make use of REST based APIs for their Zoho integration. We will be completely discontinuing support for these XML-RPC methods in a few weeks. Zoho Show's another
list of Data APIs is loosely based on the XML-RPC specification that
allows software running on disparate operating systems and different
environments to make procedure calls over the internet. To perform an
action using the Zoho Show API, you need to choose a calling
convention (GET/POST), send a request specifying the method name and
some arguments. In return, you will receive a formatted response from
the called method.
