A DepositPreauth object tracks a preauthorization from one account to another. [DepositPreauth transactions][] create these objects.
This has no effect on the processing of transactions unless the account that provided the preauthorization requires Deposit Authorization. In that case, the account that was preauthorized can send payments and other transactions directly to the account that provided the preauthorization. Preauthorizations are one-directional and have no effect on payments going the opposite direction.
A DepositPreauth object has the following fields:
Account
String
Account
Yes
The account that granted the preauthorization. (The destination of the preauthorized payments.)
Authorize
String
Account
Yes
The account that received the preauthorization. (The sender of the preauthorized payments.)
Flags
Number
UInt32
Yes
A bit-map of boolean flags enabled for this object. Currently, the protocol defines no flags for DepositPreauth objects. The value is always 0.
LedgerEntryType
String
UInt16
Yes
The value 0x0070, mapped to the string DepositPreauth, indicates that this is a DepositPreauth object.
OwnerNode
String
UInt64
Yes
A hint indicating which page of the sender's owner directory links to this object, in case the directory consists of multiple pages. Note: The object does not contain a direct link to the owner directory containing it, since that value can be derived from the Account.
PreviousTxnID
String
Hash256
Yes
The identifying hash of the transaction that most recently modified this object.
PreviousTxnLgrSeq
Number
UInt32
Yes
The [index of the ledger][Ledger Index] that contains the transaction that most recently modified this object.
The ID of a DepositPreauth object is the [SHA-512Half][] of the following values, concatenated in order:
The DepositPreauth space key (0x0070)
The AccountID of the owner of this object (the sender of the [DepositPreauth transaction][] that created this object; in other words, the one that granted the preauthorization)
The AccountID of the preauthorized account (the Authorized field of the [DepositPreauth transaction][] that created this object; in other words, the one that received the preauthorization)
