I was trying to find out a way we can use a shared process definition across multiple tenants and instantiate the process using REST API. I can see the api method (https://docs.camunda.org/manual/7.3/api-references/rest/#process-definition-start-process-instance) for instantiating a process definition using a key or an id but could not find a way to specify the tenant identifier. Am I missing anything ? Is this possible to achieve ?
To set up some context, I am trying to build my own front end and communicate with the process engine using REST API only. I have a process definition deployed with no tenant identifier specified in the processes.xml file and want to instantiate the definition with a tenant identifier and some tenant specific variable values through REST.
