How do I specify a Dropdown item?

I’ve ended up answering this question on this topic (I think :slight_smile:), but for reference to other readers, I’ll repost it here.

Considering a template with a dropdown define as such:

{
                    "document_tag_id": "ext_id_dropdown",
                    "id": "b7fc6ae3-5a64-4746-a266-408f2fa550c5",
                    "type": "dropdown",
                    "text_value": null,
                    "is_required": true,
                    "coordinates": {
                        "x": 0.157528641571195,
                        "y": 0.5615431436187784
                    },
                    "dimensions": {
                        "width": 0.2618657937806874,
                        "height": 0.021464646464646464
                    },
                    "date_value": null,
                    "page_index": 0,
                    "checkbox_value": null,
                    "document_id": "16966a7e-13a6-447a-a465-dd87e28c2565",
                    "content_type": "dropdown",
                    "dropdown_choices": [
                        "Dropdown A",
                        "Dropdown B",
                        "Dropdown C"
                    ],
                    "group_id": null,
                    "label": "drop_down"
                },

To pre select a dropdown entry in the creation of a sign request:

    {
      "document_tag_id": "ext_id_dropdown",
      "text_value": "Dropdown B"
    }
