Hi Tommy
Is this authenticated web messaging or standard?
For authenticated, this should be in the claim and accessible in Genesys Architect directly with the variables Message.Message.senderAddressInfo.email and Message.Message.senderAddressInfo.name (see here for what is available: https://help.mypurecloud.com/articles/authenticated-web-messaging-attributes/
If not, then you could pass that data across from the website, see the database plugin sdk (https://developer.genesys.cloud/commdigital/digital/webmessaging/messengersdk/SDKCommandsEvents/databasePlugin)
If the customer has provided some sort of information, you could do a contact lookup with the search external contacts action in your flow (https://help.mypurecloud.com/articles/search-external-contacts-action/)
Edit: Or is this after the fact reporting? For that you could add those details as participant data, and just do the conversation detail api to get that info
