Create a unique identifier attribute on that record that serves as the value placed in the link.
I think it then reads: https://blablabla.mendixcloud.com/link/LINKACTIONNAME/UniqueIdentifier
The deeplink knows which process to run and which record you are looking for.
I'm doing something similar with a reset password process. When a customer wants to reset their password I send them an email with a link; the link has a GUID on the end (i.e. http://localhost:8080/link/forgotpassword?123456789)
(I know that's not a valid GUID but you get the idea :)
I have a microflow called DL_ResetUserPassword that takes a string input parameter called GUID and there's some logic in there to perform the password reset in the database based on whatever GUID has been passed in. I think the Deeplink module handles multiple parameters by default so you could send in a query string with x parameters and you would just have to create x input parameters in your microflow.
I guess in your example you would take the GUID, retrieve the correct record and then load the page with a data view for that record, passing the retrieved record to it as an object.
Does that help? Let me know if you need any more info.
