You need to add an content type application/json header to your request to prevent a 405 error. Are you sure there's a process definition with that id available in the Activiti Engine?

I do have the content-type set to application/json. Here is my part of my xml code
<?xml version="1.0" encoding="UTF-8"?>
<definitions id="model" xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlnsmgdc="http://www.omg.org/spec/DD/20100524/DC" xmlnsmgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">
<process id="myProcess" name="My process" isExecutable="true">
    <serviceTask id="servicetask1" name="javaclass" activiti:async="true" activiti:class="javaclass"></serviceTask>
    <endEvent id="endevent1" name="End"></endEvent>
    <userTask id="usertask2" name="Confirm end of Pipeline" activiti:assignee="kermit">

I wanted to attach a screen shot of my postman call but I couldn't. I tried processDefinitionId, processInstanceId and processInstanceKey with value as myProcess, myProcess:1:1234 and model in my json object but nothing worked. All of these postman calls returned method not allowed, 405 error

Your url is wrong.

You need to post to process-instances, with an S at the end.

as per the user guide:

<code>
POST runtime/process-instances
</code>

The 405 is correct, cause POSTing to /process-instance is not allowed (GET is, as it fetched one process instance)
