I’m trying to create a new case instance through this endpoint: [POST /cmmn-runtime/case-instances](https://documentation.flowable.com/latest/assets/core-swagger/cmmn.html#/Case%20Instances/createCaseInstance)

This is my request body:

```auto
{
  "caseDefinitionKey": "oneTaskCase",
  "startFormVariables": [
    {
      "name": "myVariable",
      "value": "test",
    }
  ]
}

```

Flowable doesn’t create a new case instance but just lists all the existing case instances.  
Is this endpoint really the right one to create new case instances?

Hey @eztam,  
can you please verify that you are actually sending the POST request? From you description, it seems you are executing the GET request.

Hey @eztam,  
can you please check the url you are using?  
From what you describe, using a POST request, but getting all case instances as a response, it indicates you are calling the [case instance query endpoint](https://documentation.flowable.com/latest/assets/core-swagger/cmmn.html#/Case%20Instances/queryCaseInstances).

Can you please check that you are using the proper endpoint?

Greetings

Christopher
