Happy New Year!
The "ABC123" value in this case can be in a Settings table in the database as a value for a setting called "ClientTag". The Settings table might be just a table with two columns (and a rowversion column), called "Name" and "Value". This can be a table with general collection of settings that can be collected in name/value pairs.
So in this table you can have something like the following:
Then you can simply replace the "ABC123" string with a call to your service or repository that retrieves this value.
I hope this answers your question.
