create-reply-draft
Generate a draft reply to an email message in Microsoft 365, supporting JSON or MIME formats for flexible content creation and later editing before sending.
Instructions
Create a draft to reply to the sender of a message in either JSON or MIME format. When using JSON format:
Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.
If replyTo is specified in the original message, per Internet Message Format (RFC 2822), you should send the reply to the recipients in replyTo, and not the recipients in from.
You can update the draft later to add reply content to the body or change other message properties. When using MIME format:
Provide the applicable Internet message headers and the MIME content, all encoded in base64 format in the request body.
Add any attachments and S/MIME properties to the MIME content. Send the draft message in a subsequent operation. Alternatively, reply to a message in a single operation.
