How can I find the Header Message-ID

The provider changes the Message-ID when they send it, after we deliver the message to the provider.

  1. Create draft
  2. Send - returns Nylasmessage_id
  3. Wait formessage.updatedfor thatmessage_id
  4. GET the RAW /message
  5. This will return the sent message object with the updatedMessage-ID

Please note this can take up to an hour to update, though usually within 10 minutes.



View RAW message contents, i.e the header
