Path Parameters

idstringrequired

Draft id (dft_…).

Response

idstring

Draft id (dft_…).

agent_idstring

Id (agt_…) of the agent the draft is sent from, chosen when it was created.

tostring[]

The draft's recipients, always as a list, even when one address was given.

ccstring[]

The draft's Cc addresses. Absent when cc was never given; [] when it was given empty or a PATCH emptied it.

bccstring[]

The draft's Bcc addresses, who receive it but appear in none of its headers. Absent when bcc was never given; [] when it was given empty or a PATCH emptied it.

subjectstring

The draft's subject. Absent when none was given; the draft is then sent with an empty subject.

body_textstring

The draft's plain-text body. Absent when none was given.

body_htmlstring

The draft's HTML body. Absent when none was given.

reply_tostring

The address replies should go to, as given on create; absent when none was.

in_reply_to_message_idstring

Id of the message this draft answers (msg_… or rcv_…), as given on create; absent when none was.

thread_idstring

The thread the draft's message joined (thrd_…), written when the draft is sent: the thread of the message named by sent_message_id, also when the send could not be fully recorded after that message was stored (see error_message). Absent until it is sent, when a send could not be recorded far enough to store its message (no sent_message_id), once that thread is deleted, and on drafts sent before this field was filled in.

tagsobject[]

Name-value labels saved with the draft and copied onto the message when it is sent. Absent when none were given.

Show propertiesHide properties
namestring

The tag's name, as given on the send, reply or draft.

valuestring

The tag's value, as given; it may be an empty string.

send_atstring

The time the draft is scheduled for (UTC); it stays after the draft is sent. Absent when it was never scheduled or was unscheduled with send_at: null.

list_unsubscribeboolean

Whether the draft is sent with RFC 8058 one-click unsubscribe headers (list_unsubscribe on create or update; off by default). One click suppresses the recipient for the whole workspace.

statusstring

draft: saved, not scheduled. scheduled: waiting for send_at. sending: being sent now. sent: see sent_message_id. failed: the send failed, see error_message. canceled: a scheduled reply whose conversation was deleted before it went out. Only draft and scheduled drafts can be edited or sent.

One of: draft, scheduled, sending, sent, failed, canceled

sent_message_idstring

Id (msg_…) of the message the draft became when it was sent. Absent on a draft not yet sent; a sent draft whose send could not be fully recorded (see error_message) can lack it too.

error_messagestring

Why the draft is failed or canceled. On a sent draft it reports a send that went out but could not be fully recorded. Absent otherwise.

created_atstring

When the draft was created (UTC).

updated_atstring

When the draft last changed: an edit, a new schedule, or a status change as it is sent.
