remove specific tags from an organization

Hello,

Via the API, how do I remove specific tags from an organization?

I tried updating an organization, and sending an array of tags appears to be additive only and isn't to specify the full list of tags that an organization should have.

For example, call the below three times:

Endpoint: https://ourdomain.zendesk.com/api/v2/organizations/1234567890123.json

Payload:
{
    "organization": {
        "tags": [
            "entitled_platinum_support"
        ]
    }
}

All three times, the API response shows only the single tag as noted above.

But, in the UI, when we look at the organization, we see "entitled_platinum_support" 3 times:

I saw there's another endpoint to remove tags from an organization, but the documentation is pretty much non-existent, and it appears to be an endpoint to remove ALL tags.

Thanks,

Chad
