Hi @Learn_Hadoop,

  1. Click on “Add criteria”
  2. Select the criterion “Variable name”
  3. Type “approve_by”
  4. Click on the tick

Hi @Learn_Hadoop,

perform a POST request accordingly:
POST /variable-instance (link to docs)

With the following payload:

{
  "processInstanceIdIn": [
    "038324ea-1e3f-11e9-ac4d-5aeae174d7c7"
  ],
  "variableName": "approve_by"
}

Cheers,

I tried … it is giving empty response.

{
“processInstanceIdIn”: [
“my_workflow_1”
],
“variableName”: “approve_by”
}

Hi @Learn_Hadoop,

have a look at the REST API documentation:

https://docs.camunda.org/manual/7.10/reference/rest
especially here:
https://docs.camunda.org/manual/7.10/reference/rest/process-instance/get-query/#query-parameters

Here is an example: https://docs.camunda.org/manual/7.10/reference/rest/process-instance/get-query/#example.

Hope this helps, Ingo
