When setting up the Experiment Assignment Queries, what is

experiment_id, experiment_name, variation_name

? This is the SDK output that our Engineers are sending to me:

"experiment": {
      "force": null,
      "variations": [
        {
          "id_2": 2,
          "id_3": 3,
          "id_1": 1
        },
        {
          "id_1": 4,
          "id_2": 5,
          "id_3": 6
        },
        {
          "id_1": 7,
          "id_2": 8,
          "id_3": 9
        }
      ],
      "namespace": null,
      "hashAttribute": "id",
      "key": "test-json",
      "weights": [
        0.3334,
        0.3333,
        0.3333
      ],
      "active": true,
      "coverage": 1,
      "condition": null
    },
    "experimentResult": {
      "value": {
        "id_1": 7,
        "id_2": 8,
        "id_3": 9
      },
      "hashUsed": true,
      "hashAttribute": "id",
      "hashValue": "ec62aa1bc0b142348b3ea6ea0382a722",
      "inExperiment": true,
      "variationId": 2
    }

• Feature Key = Experiment ID? like

test-json

in the example above • What is an example of "Experiment Name"? Where in the GrowthBook UI is that input? • How do we get "Experiment Name" and "Variation Name" to be passed back by the SDK?

The experiment_id would be the ‘key’ inside the ‘experiment’ object. and variation_id would be the index of the variation. In. your image, the experiment name and variation name you’ve likely added as dimensions

experiment_name

and

variation_name

auto populate there as "Required columns" when I check that "Use Name Columns" option to the left

yes

Hm, ok. Still slightly confused on where 'Experiment Name' gets populated, but let me try putting in the optional 'Variation Name' and seeing if that gets returned back in the SDK. The confusing thing is that it sometimes pre-populates the variation name, so I would expect that to return in the SDK, but let me try overwriting the pre-populated values and seeing if that returns:
