Camunda 7 Topics Discussion & Questions

Hello

I have a question about getting the variables of a form using the Camunda API following the manual documentation [Get Start Form Variables | docs.camunda.org]; Process of an element Activity I send the following data by the POST method in format Json:
{
“variables”: {
“customerId”: {“value”:“Niall”,“type”:“String”},
“amount”:{“value”:100,“type”:“Double”}
}
}

In response, the following :

{
“links”: [
{
“method”: “GET”,
“href”: “http://10.1.103.46:8080/engine-rest/process-instance/1acaeba4-49f9-11e7-8014-0800275ee0b9”,
“rel”: “self”
}
],
“id”: “1acaeba4-49f9-11e7-8014-0800275ee0b9”,
“definitionId”: “64af0e19-3fd4-11e7-97c4-0800275ee0b9”,
“businessKey”: null,
“caseInstanceId”: null,
“ended”: false,
“suspended”: false,
“tenantId”: null
}

Later REST API is used :

Hi Juan Pablo,

It’s not exactly clear to me what you are trying to achieve. The request documented at https://docs.camunda.org/manual/7.7/reference/rest/process-definition/get-form-variables/ returns the start form variables of a process. Those must be defined in the BPMN XML, in particular in the Forms section of the start event’s properties. If this is not what you are after, could you please explain the goal you are trying to achieve?

Cheers,
Thorben
