Trying to bulk-update agent skill proficiencies via the CXone Admin REST API. The single-agent PATCH works fine, but the bulk endpoint /api/v2/users/skills/bulk keeps returning a 400 Bad Request. The payload looks correct based on the docs, but the error message is vague. Here’s the JSON structure I’m sending in the request body. What’s wrong with the format?
{
"skills": [
{ "skillId": "123", "proficiency": "advanced" }
]
}
