I have downloaded the flowable 6.4.2 source code and I’m going to use 3 modules in my application. 1. flowable-ui-idm 2. flowable-ui-modeler 3. flowable-ui-task I have created a small process, which involves a mail task. I have a method which makes use of `RuntimeService` and it’s method `startProcessInstanceByKey` to start the process. Problem comes when I try to call that method from another application, I used below code to make a call and the method was `GET` as well. ``` ResponseEntity triggerWorkFlow = mRestTemplate.getForEntity( "http://localhost:9999/flowable-task/app/rest/execution/start-process/"+processKey, String.class); ``` Above call, doesn’t even reach the method which starts the process, however it does through `java.net.ConnectException` when flowable-task URL is not available. Below is the value of triggerWorkFlow: ``` <200, ``` ``` Flowable IDM ``` ```

``` Method which is used to start Process is: ``` @RequestMapping(value = "/start-process/{processKey}", method = RequestMethod.GET) public void startProcess(@PathVariable("processKey") String processKey) { System.out.println("STARTING PROCESS"); mRuntimeService.startProcessInstanceByKey(processKey); } ``` I believe there is an issue with authentication but it doesn’t throw any exception anywhere. So, **how do I make this REST TEMPLATE CALL** Let me know if any details are required from my end. ---

The REST endpoint you’re looking for is `http://localhost:9999/flowable-task/process-api/runtime/process-instances` . You’ll POST a JSON object containing a `processDefinitionKey` to start the process using basic auth. There is Swagger documentation available for the Flowable REST api as part of the flowable-rest WAR at `/docs/`. It’s the same API that’s available to you in flowable-task, but the paths are slightly different. Will ---

Thanks Will !! The REST endpoint which you provided : `http://localhost:9999/flowable-task/process-api/runtime/process-instances` worked fine. And Yes, there is a similar API in flowable-task, used to start new Process Instance `http://localhost:9999/flowable-task/app/rest/process-instances` , which takes JSON object having value of `processDefinitionId` , which is again obtained from API `http://localhost:9999/flowable-task/app/rest/process-definitions?latest=true` , whose response is, ```auto { "size": 1, "total": 1, "start": 0, "data": [ { "id": "processdemo:2:b7e88899-c4c2-11e9-93d6-525349d6ad33",//processDefinitionId "name": "ProcessDemo", "description": null, "key": "processdemo", "category": "http://www.flowable.org/processdef", "version": 2, "deploymentId": "b7cb8ab6-c4c2-11e9-93d6-525349d6ad33", "tenantId": "", "hasStartForm": false } ] } ``` When using above `processDefinitionId` as request body for API, `http://localhost:9999/flowable-task/app/rest/process-instances` , I am able to start the process from Swagger of flowable-ui-task, but if I try to start the process from POSTMAN, it behaves in the same way I described in my question. **(process doesn’t get started and nothing happens in flowable-ui-task console in IDE)** I’m gonna use the endpoint which you provided, but I’m not sure why it doesn’t work ---

- What does Postman show when dong the call? It should show at least the status code - Are you sure you’re running all of the apps against the same database? ---

Hi Joram, I started using floowable as a dependency now and don’t remember now what was the status code and yes all flowable apps were using same database, which I changed in flowable-default.properties ---

In that case I’m a bit puzzled … typically that’s the problem. Can you maybe check your database (e.g. the ACT\_RU\_EXECUTION) table to see if data gets actually added?
