This is the hash key of the attributes which make up the composite key--- TransactionKey and AddedDate ---for the Related Transactions resource and used to uniquely identify an instance of Related Transactions. The client should not generate the hash key value. Instead, the client should query on the Related Transactions collection resource with a filter on the primary key values in order to navigate to a specific instance of Related Transactions.
For example: publicSectorRelatedTransactions?q=TransactionKey=<value1>;AddedDate=<value2>
