If references passed in the request are related to more than one conversation, the draft will be appended to the first conversation found. If no reference is provided, the draft will be created in a new conversation. If one or more references are provided but none of them match an existing conversation, the draft will be created in a new conversation.

Chevrons around references are optional. Both ["<some-reference-123>"] and ["some-reference-123"] would reference the same conversation. References must not contain whitespace.

add_assignees

add_assignees lets you assign users to the conversation. Existing assignees will remain assigned. When providing add_assignees, the organization field is required.

add_shared_labels, remove_shared_labels

add_shared_labels and remove_shared_labels let you manage shared labels that are applied to the draft’s conversation.

add_to_team_inbox

add_to_inbox

add_to_inbox lets you move the draft’s conversation to Inbox for everyone having access to the conversation.
