Create or Update a Suppression documented response doesn't match actual response

The documentation for the Create or Update a Suppression endpoint has the following 200 response example:

{
    "results": {
        "message": "Suppression List successfully updated"
    }
}

However, the actual response received is:

{
    "results": "Suppression List successfully updated"
}

Did this change at some point? Is the documentation out of date? Is other related documentation possibly inaccurate as well?

Start at content/api/suppression-list.apib around line 104 and compare the documented 200 response with the actual response shown in the issue. Check related suppression endpoint examples for the same mismatch, then update the documentation where needed so the response shape matches reality.
