Update a process instance

Details

URI	/processinstances/<process_instance_id> Where <process_instance_id> is the process instance ID.
Method	PUT
Parameters	userIdentifier=<user_id>     Required; the user ID you want to use as credentials for this API call. See Get userIdentifier for the steps required to get the userIdentifier value. view=<view_type>&scope=view     Optional; used to update process instance based on pre-defined views. Possible values for view_type are propertyinfo and processinstancestate. With processinstancestate, the process instance state, return code and status can be changed. <property_>action<_>=merge    Optional; use the merge option with the action meta tag query parameter to update only a portion of the process instance. The following the use cases are allowed: With view=propertyinfo, specifying property_action_=merge will merge the properties specified in the request body with the existing process instance properties. With view=processinstancestate, specifying action=merge will merge the state information specified in the request body with the existing process instance state.
Request Body	ProcessInstance VO
Response Body	Updated ProcessInstance VO
Returns	200 - Ok 401 - Not authorized 404 - Not found 500 - Server exception

Process instance state (processInstanceState) values:

• INITIALIZED
• PENDING
• READY
• ACTIVE
• COMPLETED
• ERROR
• CANCELED

Process instance return code (processReturnCode) values:

• SUCCESS
• FAILURE
• RUNNING
• TIMEOUT

The request body sent in the API will be strictly validated for the following:

 

• Process Instance Id sent has to exist in CSA, otherwise the call will fail with appropriate error message.
• Process Instance state will be validated using the rule that the state cannot be changed to a transitional state while it is already in a terminal state. The terminal states are ‘COMPLETED, ERROR, CANCELED’ . So if the process instance state is already in any of the above states, this call will fail if it attempts to set the state to a different value than what it is currently. In addition, a process instance which is already in Active state cannot be reset back to Ready state using this call.
