No, this is not exactly was was needed. The apidoc tells about the following JSONs in response for a list of namespaces:
{
-
"updateTime": 1572918753626,
-
"code": "Email",
-
"status": "ACTIVE",
-
"createTime": 1572918753626,
-
"description": "Email",
-
"idType": "CROSS_DEVICE",
-
"name": "Loyalty Member ID",
-
"id": 6,
-
"custom": false
}
There are standard ID namespaces listed here but without such details.
