Hi,
You have to use the Describe Entities method with your picklist type (the one that you find in the "Class API Name" field of the Picklist edit page):
This returns all picklist values:
{
"entityDescriptions": [
{
"pickups": [
{
"value": "value1",
"displayValue": "value1",
"description": "value1",
"color": "#999999"
},
{
"value": "value2",
"displayValue": "value2",
"description": "value2",
"color": "#FF0000"
},
{
"value": "value3",
"displayValue": "value3",
"description": "value3",
"color": "#FF9900"
}
],
"customizable": true,
"typeName": "C_EnhancementRequestHodderEducationService",
"validStates": [],
"label": "Hodder Education Service",
"labelPlural": "",
"displayField": "Name"
}
]
}
