WikiPathways can be accessed programmatically through a REST web service. These services provide powerful means to query, access and interact with the pathway content at WikiPathways.  
-
WikiPathways can be accessed through a [[wikipedia:SOAP|SOAP]] webservice. This page contains documentation for the webservice API.

== Examples ==
+
-
=== Java ===
+
-
Check out [http://svn.bigcat.unimaas.nl/pathvisio/trunk/tools/soap-axis2/ the subversion repository] for example code on how to call the webservice from Java with [http://ws.apache.org/axis2/ Apache Axis 2].

==== login ====
+
=== Working with GPML ===
-
Start a logged in session, using an existing WikiPathways account. This function will return an authentication code that can be used to excecute methods that need authentication (e.g. updatePathway).
+
The pathways on WikiPathways are stored in the GPML format. This is an XML format and can be processed in any programming language. See [http://developers.pathvisio.org/wiki/EverythingGpml here] for the GPML specification. If you are developing in Java, we recommend using our [[#Java libraries|Java libraries]].
