Trying to create a new outbound contact list via the API. Getting a 400 Bad Request with INVALID_VALUE. The error points to the name field, but it’s just a simple string.
{
"name": "Test List 1",
"label": "Test",
"description": "API test"
}
I’ve checked the docs and the name is valid. Tried changing it to alphanumeric only. Same error. Is there a hidden uniqueness constraint or format rule I’m missing?
