Blacklist one or more creators so outreach automations stop targeting them.

Handles are normalized before storage (a leading @ and surrounding whitespace are stripped, the handle is lowercased), so @Creator and creator are the same entry. The call is additive and forgiving: handles already on the list are counted in duplicates_skipped, malformed handles (URLs, blanks) in invalid_skipped — neither fails the request, so a partially valid batch still applies. Check added_count for what actually changed.

At most 500 handles per request. Requires a key with read_write scope and a single shop.

{
  "creators": [
    "@somecreator",
    "another.creator"
  ]
