You should check your Body format first. From error it looks like you have missed recipients Example body format { "From": "sender@example.com", "To": "receiver@example.com", "Cc": "copied@example.com", "Bcc": "blind-copied@example.com", "Subject": "Test", "Tag": "Invitation", "HtmlBody": " Hello ", "TextBody": "Hello", "ReplyTo": "reply@example.com", "Headers": [ { "Name": "CUSTOM-HEADER", "Value": "value" } ], "TrackOpens": true, "TrackLinks": "None", "Attachments": [ { "Name": "readme.txt", "Content": "dGVzdCBjb250ZW50", "ContentType": "text/plain" }, { "Name": "report.pdf", "Content": "dGVzdCBjb250ZW50", "ContentType": "application/octet-stream" }, { "Name": "image.jpg", "ContentID": "cid:image.jpg", "Content": "dGVzdCBjb250ZW50", "ContentType": "image/jpeg" } ], "Metadata": { "color":"blue", "client-id":"12345" }, "MessageStream": "outbound" }
