Write lock

The write lock is used to implement optimistic concurrency. It is optional. A

writeLock

is returned for each balance or inventory item instance when they are fetched, added or updated. The user can then pass the

writeLock

value back to the SDK when updating a currency balance or inventory instance. If it matches, the request is successful and will update. If it doesn't, then an error is returned. The

writeLock

can be any

string

value. For a code example, see the method

UpdatePlayersInventoryItemUsingWriteLock

in the

InventoriesBasicExample

sample.
