Have email reply end up in original conversation

[Thomas_Van_Durme]

When a customer replies on an email that has been sent using the below API, that email ends up in the original conversation.
/api/v2/conversations/emails/{conversationId}/messages

Question: if you send an email using a different platform with regards to a specific conversation in Genesys, is it possible to have a customer reply on that email end up in that conversation in Genesys?

One would assume that maybe specific email headers are present that make sure an email-reply effectively ends up in its original conversation?

Example: when messages are sent using "Sent auto reply" by Architect, there is an attribute on the conversation: conversation.participant.email.messageId that matches with elements in the email headers. See screenshots.
Could this be potentially used?

Hello,

Someone from engineering pointed me to this Resource Center page which explains how the email messages are threaded in a conversation.
This leverages the In-Reply-To and References email headers.

"Genesys Cloud threads email messages based on the “In reply to” header and the “References” header. This process ensures that messages that originate from certain email clients and contain the same subject and sender information but are unrelated, are no longer associated with each other."

Regards,
