We are making automation process to split out user traffic with geo-based rule with GTM.
According to the spec described on developer page, both GTM property create and update have to return "201 Created" response code for inquiry.
But it looks 1) 201 responded in case of creation, but 200 responded in case of property update.
We are developing error handling logic based on response code, but weird symptom that is different from developer guide making confusion.

Let's make us clear on this!
