Transaction

		|Transactions are records of successful movements of value into or out of an `Account`.
		|
		|OBP Transactions don't contain any "draft" or "pending" Transactions; pending transactions see represented by Transaction Requests.
		|
		|OBP Transactions are modelled on a Bank statement where everything is based on the perspective of my account.
		|That is, if I look at "my account", I see credits (positive numbers) and debits (negative numbers)

		|An OBP transaction stores information including the:
		|Bank ID
		|Account ID
		|Currency
		|Amount (positive for a credit, negative for a debit)
		|Date
		|Counterparty (information that describes the other party in the transaction)
		|- optionally description and new balance.

| |Note, OBP operates a Double-Entry Bookkeeping system which means that every transfer of value within OBP is represented by two transactions. | |For instance, to represent 5 Euros going from Account A to Account B, we would have 2 transactions: | |Transaction 1. | |Account: A |Currency: EUR |Amount: -5 |CounterpartyCounterpartyCounterparty: Account B | |Transaction 2. | |Account: B |Currency: EUR |Amount: +5 |Counterparty: Account A | |The sum of the two transactions must be zero. | |What about representing value coming into or out of the system? Here we use "settlement accounts": | |OBP-INCOMING-SETTLEMENT-ACCOUNT is typically the ID for a default incoming settlement account | |OBP-OUTGOING-SETTLEMENT-ACCOUNT is typically the ID for a default outgoing settlement account | |See the following diagram: | | | |See the Get Double Entry Transaction endpoint | | |
