## add_heyreach_leads
Push up to 100 leads into a HeyReach campaign (optionally pinned to a sender) or a HeyReach list, and report how many were added, updated, or failed.
Use to enroll the leads a person chose into LinkedIn outreach. The server derives the replay key from the chosen leads and returns the first result on retry.
Enrolling leads starts real LinkedIn actions and is refused on a frozen subscription. A reused key with DIFFERENT leads is a conflict, and a key whose first attempt never got an answer from HeyReach stays a conflict — check the campaign's leads before choosing a new key, because a blind retry could enroll everyone twice.
Obtain the user's explicit authorization before invoking a write or destructive action. This is a client interaction requirement, not a server-issued approval token.
Scopes: integration:update, campaign:launch
Risk: costly; confirmation: explicit; idempotency: supported.
