&lt;p&gt;1.&amp;nbsp;Check&lt;span&gt;&amp;nbsp;if the user account , with whom you have registered your third-party credentials has proper required rights/ privileges&amp;nbsp;for the web API&amp;nbsp;/ data&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;2.&amp;nbsp;The process parameters needs to be a list of dictionary.500 error can be caused by&amp;nbsp;the process parameters that are not getting passed, and so the process does not start.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;3. Check the mandatory parameters for the process model you are trying to start. You need to pass input for all of them else the error will come.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
