API actions (transactions)

Action	Description
createTransaction	returns a `"transactionId"` property that you can add to other actions to put them under control of this transaction. Until you run `"commitTransaction"`, changes made inside the transaction are invisible outside the transaction and are not durably persisted; thus, if the server fails before the transaction commits, all actions in the transaction are automatically rolled back.
createTransactionSavePoint	bookmarks the current point in the transaction process. You can create multiple savepoints and use `"revertTransactionToSavepoint"` to undo changes made after the savepoint.
revertTransactionToSavepoint	reverts a transaction back to a savepoint previously created by `"createTransactionSavepoint"` . It keeps the transaction open so you can continue to do more actions under transaction control.
commitTransaction	closes a transaction and makes its changes durable and visible to other transactions. You can include the `"transactionSavepointId"` property to commit changes in the transaction up to the savepoint. `"commitTransaction"` always closes a transaction. Once a transaction is closed, you can no longer use its `"transactionId"`.
rollbackTransaction	closes a transaction and discards all changes made under the control of the transaction. Once a transaction is closed, you can no longer use its `"transactionId"`.
listTransactions	returns a list of all active transactions that the logged-in account is authorized to see.
