Definition
This resource represents the net increases and decreases in an account (AccountId) at a specific point in time.
An account (AccountId) can have multiple balance types (these follow the standard ISO 20022 balance type enumerations). If an API Provider includes a credit line in an available balance - then the balance representation will have a section for the credit line amount and type.
Endpoints
| Resource | Endpoint | Mandatory? | Scope | Grant Type | Idempotency Key | Parameters | Request Object | Response Object |
|---|---|---|---|---|---|---|---|---|
| balances | GET /accounts/{AccountId}/balances | Mandatory | accounts | Redirect Flow; or Decoupled Flow | No | OBReadBalance1 | ||
| balances | GET /balances | Optional | accounts | Redirect Flow; or Decoupled Flow | No | Pagination | OBReadBalance1 |
GET /accounts/{AccountId}/balances
The API endpoint allows a Third Party to retrieve the account balance information resource for a specific AccountId (which is retrieved in the call to GET /accounts).
- The Third Party must have an access token issued by the API Provider using an authorization flow (either redirect flow or decoupled flow).
GET /balances
The API endpoint allows a Third Party to retrieve the account balance resources in bulk, if an API Provider has implemented the bulk retrieval endpoints.
- The Third Party must have an access token issued by the API Provider using an authorization flow (either redirect flow or decoupled flow).
- This will retrieve the resources for all accounts linked to the account-access-consent.
Data Model
The OBReadBalance1 object will be used for the call to:
- GET /accounts/{AccountId}/balances
- GET /balances
UML Diagram
Notes
- Multiple balances can be returned (each with a different value for Type) for an account. This is for API Providers that show multiple balances in their online channels.
- The CreditLine section can be repeated - as multiple credit lines may be included in an available balance.
- A DateTime element has been used instead of a complex choice element of Date and DateTime. Where time elements do not exist in API Provider systems - the time portion of the DateTime element will be defaulted to 00:00:00+00:00
Permission Codes
The resource requires the ReadBalances permission. The resource response payload does not differ depending on the permissions granted.

Enumerations
This section gives the definitions for enumerations used.
| Code Class | Name | Definition |
|---|---|---|
| OBBalanceType1Code | ClosingAvailable | Closing balance of amount of money that is at the disposal of the account owner on the date specified. |
| OBBalanceType1Code | ClosingBooked | Balance of the account at the end of the pre-agreed account reporting period. It is the sum of the opening booked balance at the beginning of the period and all entries booked to the account during the pre-agreed account reporting period. |
| OBBalanceType1Code | Expected | Balance, composed of booked entries and pending items known at the time of calculation , which projects the end of day balance if everything is booked on the account and no other entry is posted. |
| OBBalanceType1Code | ForwardAvailable | Forward available balance of money that is at the disposal of the account owner on the date specified. |
| OBBalanceType1Code | Information | Balance for informational purposes. |
| OBBalanceType1Code | InterimAvailable | Opening booked balance, plus today's credits, plus overdraft facility (if held) minus today debits, minus uncleared funds (note: uncleared funds equal the total of uncleared banked minus any uncleared funds amount held). This is the total available funds the customer is able to access. E.g. Interim Available Balance = Opening Booked Balance + Today's Credits + Overdraft Limit - Today's Debits - Uncleared Funds |
| OBBalanceType1Code | InterimBooked | This balance will be calculated at individual bank level as per existing internal definitions to ensure consistency for customers. What is included in the displayed balance may differ between banks. E.g. The balance of the account at a point in time / intraday / real time when requested, which may or may not include uncleared funds. |
| OBBalanceType1Code | OpeningAvailable | Opening balance of amount of money that is at the disposal of the account owner on the date specified. |
| OBBalanceType1Code | OpeningBooked | Opening Balance of an account at the end of batch processing that interest and fees are calculated on. This is the same balance as Previously Closed Booked Balance. Includes any uncleared funds, regardless of uncleared funds limits. E.g. balance after end of day process. |
| OBBalanceType1Code | PreviouslyClosedBooked | Balance of the account at the previously closed account reporting period. The opening booked balance for the new period has to be equal to this balance. Usage: the previously booked closing balance should equal (inclusive date) the booked closing balance of the date it references and equal the actual booked opening balance of the current date. |
| OBCreditDebitCode | Credit | Operation is a credit |
| OBCreditDebitCode | Debit | Operation is a debit |
| OBExternalLimitType1Code | Pre-Agreed | The amount of an arranged lending limit that has been agreed with the account holder |
| OBExternalLimitType1Code | Temporary | The amount of a temporary lending limit that has been agreed with the account holder |
| OBExternalLimitType1Code | Emergency | The amount of an arranged lending limit that can be borrowed on top of pre-agreed lending, that has been agreed with the account holder. |
