Make you a deal, highlight that as actual JSON (JS in the syntax highlighter) and I'll figure it out for you. 
Thanks Sanford. Let's see:
My page and form: https://marketo-demo.reply.eu/Visi_API.html
Visibility Rules for the field "State". The picklist shall change based on the selection in "Country".
Now I want to do this via API. Following the instruction here (https://developers.marketo.com/rest-api/assets/forms/#visibility_rule), this URL and Payload work fine:
POST: {{base_url}}/rest/asset/v1/form/1360/field/Email/visibility.json
BODY:
visibilityRule={
"ruleType":"show",
"rules":[
{
"subjectField": "LastName",
"operator": "isNotEmpty",
"values": [],
"altLabel": "Email:"
}
]
}
Now, let's transfer this to the Country and State. In its basic form it would look like this:
POST: {{base_url}}/rest/asset/v1/form/1360/field/State/visibility.json
BODY:
visibilityRule={
"ruleType":"show",
"rules":[
{
"subjectField": "Country",
"operator": "isNotEmpty",
"values": [],
"altLabel": "State:"
}
]
}
Now I get this error message:
{
"requestId": "d1f#1906fc9ebfd",
"success": false,
"warnings": [],
"errors": [
{
"code": "709",
"message": "Field of type radio buttons, checkboxes and select should have picklist values."
}
]
}
Alright, both Country and State are select type fields, so what is this error message referring to? Country? State? Both?
Next try, and this payload is an exact copy of the respective GET request: {{base_url}}/rest/asset/v1/form/1360/fields.json
{
"visibilityRules": [
{
"ruleType": "show",
"rules": [
{
"subjectField": "Country",
"operator": "is",
"values": ["Germany"]
}
],
"picklistValues": [
{
"label": "Select...",
"value": ""
},
{
"label": "CA",
"value": "CA"
},
{
"label": "CO",
"value": "CO"
}
]
},
{
"ruleType": "show",
"rules": [
{
"subjectField": "Country",
"operator": "is",
"values": ["Austria"]
}
],
"picklistValues": [
{
"label": "Select...",
"value": ""
},
{
"label": "AR",
"value": "AR"
},
{
"label": "AZ",
"value": "AZ"
}
]
}
]
}
Response:
{
"success": false,
"errors": [
{
"message": "Invalid ruleType.",
"code": "701"
}
],
"requestId": "36f#1906fe772b6",
"warnings": []
}
Any idea?
