What it means
Your partner account has been suspended, so partner-level operations are refused. This is distinct frominsufficient_scope,
which is about a single token’s scopes — partner_suspended applies to the
whole client regardless of the token presented.
Today this is only returned by GET /v1/webhooks/test, since that is the
one partner-level action in the public API. A suspended partner’s existing
access tokens continue to authenticate against the read endpoints until they
expire.
What to do
There’s nothing to fix in your request. Suspension is an account-level state set by DSS. Contact admin@digitalseaservice.com, quoting theinstance request ID, to find out why and to get reinstated.
