Check whether a LinkedIn message went out
Ask what a LinkedIn message send came to, without sending: by the client_reference it went out under (optionally at one place: linkedin_conversation_sid, ln_member_id or profile_urn), or by the activity_log_sid a 409 named. result.outcome: sent (item is the message, or null with reason message_row_pending or caller_confirmed), in_flight, unknown (the thread has not shown it yet; retry_after, send_decisive_at), or not_sent (no_send_under_key, refused, not_in_thread, caller_confirmed). Send the same request again only on not_sent, under the same key. result.activity_log_sid is the attempt a person’s word names (confirmed_not_sent / confirmed_sent on the send tools). A send in doubt has its thread read now when a look is due, so a call can be slow. A key sent to several places is 422 place_required, a place in another form than the sends recorded 422 place_unmatched (context.places). Invitations: check_linkedin_connection_request_sent; comments, posts, reposts: check_linkedin_posting_sent.

}Authorizations
Access token issued by gtm.service.id. Its access_identity claim carries team_sid, actor_sid and actor_type, and that team scope is authoritative.
Team scope for tokens that do not carry one. Ignored when the token already names a team.
Body
application/json
Request body of check_linkedin_message_sent.
The account that sent (ln_ac_…). A key is looked up on this account only.
Required string length:
18Pattern:
^ln_ac_The key the send went out under, byte for byte. Exactly one of client_reference / activity_log_sid. Found at any age: a send in doubt never ages out of its key.
Required string length:
1 - 255The attempt a 409 or an earlier check named (ln_al_…); it takes no place. An attempt of another account is 404.
Required string length:
18Pattern:
^ln_al_Place, next to client_reference: the thread the send named or landed in. One place at most; a thread of another account is 404.
Required string length:
18Pattern:
^ln_cv_Place, next to client_reference: the person's member id (digits).
Maximum string length:
64Place, next to client_reference: the recipient id the send was given (ln_id ACoAA…, sn_id ACwAA…, or a Recruiter id).
Maximum string length:
128Response
action success envelope.
Available options:
true Available options:
action kebab-case verb; matches the route segment.
