Trying to create a new outbound contact list via the Genesys Cloud API. Getting a 400 INVALID_VALUE error on POST to /api/v2/outbound/contactlists.
POST /api/v2/outbound/contactlists
{
"name": "test_list",
"description": "trace test",
"addressBooks": [{"id": "123"}]
}
The address book ID exists. Trace context is attached via headers but that shouldn’t block creation. Any idea what field is throwing this off?
