How to extract internet_message_id

I’m trying to use a combination of Nylas and MS Graph API. Now MS Graph API uses internet_message_id which is not present in Nylas.

Is there a way I can extract this?

Thank you in advance.

To find this, you’ll need to download the full email headers from the /message endpoint. Once you have the full headers, just look for the line labeled Message-ID. Let us know if you have any problems.
