The rest-api does not support starting processes by an event, so it seems. Any reason why you need a message start-event and not using a none-start event (maybe you have 2 separate message-start-events?).

I'll make sure that functionality is in the 5.15 release…

An alternative workaround can be to use a none-start event, and have an event-based gateway with 2 intermediate message-events and start the process by key through rest and message it through rest, selecting the right message.

Seems like it's already implemented in 5.14, but the docs have a bad example (my bad):


POST runtime/process-instances Request body (start by message):

{
   "message":"newOrderMessage",
   "businessKey":"myBusinessKey",
   "variables": [
      {
        "name":"myVar",
        "value":"This is a variable",
      },
      
      … 
   \]
}
[code]

What alternative way you want? You can use use REST-API or java-api. If you cant to send a message-event within a process, you can use a message-start event in an event-subprocess (see userguide).
