I'm using cloud-hosted.
I've refer to that link before, but I don't know
- which support to choose to open case
- where to include the ES URL and Domain ID
Really appreciate if you could you show me step by step in details.
The cloud-hosted in the article means the ES server provisioned by PTC and is hosted on PTC Cloud.
If that is your case, you should be provided with 100 ThingMarks already.
If you installed Experience Service by yourself on a Cloud Server, that should be regarded as On-Premise Experience Service.
For initial ThingMarks request for OnPrem ES (no existing ThingMarks), raise a technical support ticket with below link - select product Vuforia Studio, state how many ThingMarks you want in the issue description when raising support case - the support team will register a domain ID for you and generate ThingMarks as per your request.
