Known issues with the latest versions of Open Banking specifications are detailed here. For each release, we have included a table that shows the issue and also any impact and/or mitigation.

This page is NOT concerned with issues relating to the implementation of the specifications (either by an ASPSP or a TPP) or for documentation and guides, but ONLY for the actual specifications. In many cases, these issues have already been fixed in a release candidate for the next version, which is available to all registered users in the Open Banking Collaboration Space.

To report any other issues, please log via the Open Banking Service Desk.

v40_KI1	Open	Spec pages have OBCashAccountDebtor4 listed against Debtor and DebtorAccount in OBDomestic2 https://openbankinguk.github.io/read-write-api-site3/v4.0/resources-and-data-models/pisp/domestic-payment-consents.html#data-dictionary	In v3 the these objects contained the same fields and shared a base object (OBCashAccountDebtor4). In v4: DebtorAccount includes the new Proxy object Debtor includes the new LEI field. The initial release still referenced OBCashAccountDebtor4 for both these objects. We will address this in a future release, the swaggers contain in-line definitions for some objects so payloads are unaffected.	Specs in future release Swagger - update in future release (to remove in-line definitions)	Specs	ASPSP	Jul 2024	00049617 00049681 00049811

v40_KI3	Closed	The OBRemittanceInformation2/Unstructured data dictionary has the correct cardinality but the class column does not clearly indicate this is an array of Max140Text values. JSON examples show as a single entity rather than an array and Swagger has a length of 256 for the strings	OBRemittanceInformation2/Unstructured is an array of strings with Max140Text length each, as shown by the cardinality. The Data Dictionary class column will be updated in future release to further clarify this. JSON examples will be updated in a future release and swagger will be updated in due course	Specs - updated 19th September 2024 Swagger - updated 19th September 2024	Spec	APSPS	Jul 2024	00049781

v40_KI6	Closed	OBWritePaymentDetails1 data dictionary is missing and UML shows wrong cardinality for Data and PaymentDetails. VRP Payment details have been rolled back to v3 schema with ISO20022 values but table still shows the v4 changes	The data dictionary will be restored. Swagger cardinality will be updated to show that Data is a singular mandatory field and PaymentStatus is an unbounded array of payment status details.

v40_KI7	Open	VRP & PISP Class name for the 'refund' object is misaligned between the data dictionary and swaggers The data dictionary assigns the refund object class as "OBDomesticRefundAccount1" and in the swaggers this is defined inline without a class (PISP) or as OBCashAccountDebtorWithName (VRP).

The parent object, MandateRelatedInformation, will be mandatory in a future update.	Spec pages - next release Swaggers - updated 19th September 2024	PISP	ASPSP	September 2024
v40_KI11	Open	v4 File Payments status codes do not represent both the status of both file processing and subsequent payments within the file itself.	The codes will be rolled back to v3 alignment but with ISO 20022 values. This ensures file status and payment details payloads can be returned successfully as per v3 implementations.

Fix to section - Consent revocation

https://openbankinguk.github.io/read-write-api-site3/v3.1.9/profiles/vrp-profile.html#consent-revocation

A PSU may revoke consent for initiation of any future payment orders, by revoking the authorisation of VRP Consent, at any point in time.

The PSU may request the TPP to revoke the consent that it has authorised. If consent is revoked with the TPP:

The TPP must cease to initiate any future payment orders or Funds Confirmations using the VRP Consent.
The TPP must call the DELETE operation on the VRP Consent resource to indicate to the ASPSP that the PSU has revoked consent.

The PSU may revoke the VRP ~~Consent~~ access via ASPSP's online channel. If the ~~consent~~ access is revoked via ASPSP:

~~The ASPSP must immediately update the VRP Consent resource status to Revoked.~~
The ASPSP must fail any future payment order request using the ConsentId, ~~with the Status Revoked.~~
The ASPSP must make a Notification Event available for the TPP to poll/deliver Real-Time Event Notification for the event - consent-~~authorization~~-access-revoked.
The ASPSP must take the necessary action to revoke access e.g. by revoking/expiring the access token provided to the PISP.
The status of the domestic-vrp-consents must remain unchanged and the PISP must be allowed to request PSU to re-authenticate the same domestic-vrp-consents resource.
Upon successful re-authentication by PSU, an ASPSP may issue new authorization code and subsequently new access token to the PISP.

Minor Bug

software_id field length and pattern is not correct (^[0-9a-zA-Z]{1,18}$). It should be 22 characters( fixed in V3.2 onwards)

We're having issues with dynamic client registration. The validation for the "iss" field in the OBRegistrationRequest1 object (in DCR v3.1) is as follows:

^[0-9a-zA-Z]{1,18}$

The guidance for this is as follows:

For SSAs issued by the OB Directory, this must be the software_id

But the software_id issued in the OB directory is 22 characters in length so is not valid according to the spec. I've noticed the 3.2 registration spec does allow for this length, but most banks don't support this registration version yet. We can register with banks that don't validate this or banks that implement the 3.2 spec, but by the looks of our registration attempts Nationwide validates the length and doesn't implement the 3.2 spec. I'd imagine there are more banks in a similar position. How do you suggest working around this issue in the mean time?

banks must provide a workaround for. The customer must contact Nationwide directly for support. If he/she is not getting the required support, he/she should raise a new ticket complaining about Nationwide and OBIE Central Testing team will get involved.

Fixed		Minor Bug	The status model for the Domestic and International Payments (Immediate) does not contain a transition from `AcceptedSettlementInProcess` that handles error cases.	A transition from `AcceptedSettlementInProcess` to `Rejected` should be included on the status model diagram. This would bring it back in line with the current status model in v1.1	Amend the specification in v3.1 to include a transition from `AcceptedSettlementInProcess` to `Rejected.`
Fixed		Errata	v3 RC3 International Standing Orders page - Reusable Class UML Diagram is incorrect.	v3 RC3 International Standing Orders page.

Section 3.6 of the V3 RC3 specification incorrectly specifies following: ASPSPs must respond with error response in the OAuth/OIDC flow with mandatory alignment of error codes to those specified in RFC 6749 Section 4.1.2.1 However, ASPSPs may extend the error response codes to include OIDC error responses as well.	The sentence should read: It must be changed to the following, to include a reference to OIDC Error Codes: ASPSPs must respond with error response in the Authorisation flow with mandatory alignment of error codes to those specified in Section 3.1.2.6 Authentication Error Response of OIDC Core specification. This will be updated in v3.1

Read/Write API v1.1

References:

This version of the Read/Write API Specification will be supported by all CMA9 ASPSPs from 13 Jan 2018. The following table details known issues with this version of the specification.

Status	Ref	Type	Issue	Details	Impact/Mitigation
Closed	CDRW-928	Minor bug	Security Profile / Signing: Ensure we have got B64Enc v/s B64URLEnc.	In the security profile, step 3 "Form the payload to be signed " provides an example that Base64 encodes JOSE header and json. Similarly the signature that is computed in Step 4 of the documentation is highlighted in the example as Base64 encoded formatted. The RFC 7515 states that the header and json is encoded in Base64URL format and not Base64. The security profile should be updated to match RFC 7515.	ASPSPs and TPPs should be advised in the documentation to follow the RFC in this case. Fixed in v3
Closed	CDRW-929	Minor bug	Links format in swagger and example on Confluence doesn't match.	The Links object in the swagger contains fields with format as URI and this can be absolute URI but the examples on confluence take in values as relative URI The standard for sending links to the consumer should be absolute URI.	ASPSPs and TPPs should be advised in the documentation to use absolute URIs. Fixed
Open	TBC	Minor clarification	OB Security Profile has been incorrectly interpreted by an ASPSP.	Clarification to reflect that TPPs are NOT required to pass ACR values in either the requested acr_values string or inside the request object to address a possible mis-interpretation. This is a MAY and not a MUST as already stated in v1.1.0 of the specification.	No impact as long as ASPSPs and TPPs follow the existing spec. Wording will be made clearer/more explicit in next release. Security Profile Implementation Guide to be updated and published
Closed	TBC	Minor clarification	Security Profile: Clarity on use of MA-TLS with OIDC well-known end-point.	Clarification to reflect that an ASPSP's OIDC well-known end-point MUST NOT use TLS-MA. The end-point SHOULD use TLS.	No impact on ASPSPs and TPPs that have followed the existing specification. Wording will be improved and made more explicit in the next release. Fixed Security Profile 1.1.2
Closed	TBC	Minor bug	Directory: The mechanism that OB uses to calculate x5t does not meet specification.	Any participant attempting to check certificates fingerprints against the x5t parameter will find validation errors. As a result of this issue, the kid field for all JWK's in the OB stores do not confirmed to the published specification where OB committed to keeping the "kid" the same as the "x5t".	Potential impact on participants that rely on x5t being correct in order to accept a jwk as valid. Any participant that is following the OB specification and dynamically calculating the appropriate kid to use when creating JWT's will reject all messages from TPPs. OB will implement a workaround for effected participants at start of managed rollout, and implement a permanent fix and update the specifications asap after 13 Jan. Fixed
Closed	TBC	Minor clarification	Update Security Profile page in Confluence to align to version in Bitbucket	The master version of the Security Profile is held in Bitbucket. The Confluence page has not been kept up to date with changes to the master, and requires a cut-and-paste to align.	The differences are non-normative, and the master is linked in the Confluence page, but these changes should be reflected for completeness. All references are now link to the bitbucket. Fixed
Closed	TBC	Minor clarification	Security Profile: Clarity on the use of ciphers for the PSU facing Authorization end-point	Clarification to reflect that the ASPSP's are free to support a more expansive list of TLS Ciphers on the Authorization Server Endpoint than is explicitly supported by the FAPI Read Write Security Profile section 8.6	The differences are non TPP or ASPSP impacting as this clarification item is related to ASPSP → PSU communication link only. Will require collaboration with the OIDF FAPI Working Group. https://bitbucket.org/openid/fapi/issues/129/tls-cipher-restrictions-should-be-relaxed Fixed Security Profile 1.1.2
Closed	TBC	Medium Implementation bug	Directory Services: The x5t and x5t256 values of the JWKS files are being calculated incorrectly.	There's an implementation defect in the way the x5t and x5t256 values of the JWKS files are being calculated. As a result, any participant relying on these values to correlate to the corresponding certificate will not be able to match the two values. The x5c and x5u values are correct and do match the public keys in the JWK.	Only one participant so far has called this out as an impacting issue however a process has been put in place to address any JWKs manually that are utilised by a TPP. A code change will be delivered to correct this generation process as soon as possible and existing JWKS entries will be updated. Fixed
Closed	TBC	Minor specification issue	Open Banking Security Profile: The KID for each JWK in the JWKS store isn't being calculated in the way that was indicated.	The specification for KID calculation indicates that "OBIE will keep the KID's the same as the x5t". The implementation hasn't followed this intention. The way KID is currently being calculated is the SHA1 of the JWK instead of the SHA1 of the DER Encoded Certificate.	Open Banking will not change the way KIDs are calculated but will update the specifications to reference the way KID is being generated. Fixed in directory spec
Closed	TBC	Minor specification issue	Read/Write API Specifications: Beneficiaries endpoint does not cater for all international benficiaries	The current beneficiaries endpoint only allows for beneficiaries which have a sort code and account number or IBAN. Some international beneficiaries are identified by other local identification schemes.	Some ASPSPs will not be able to share all details for some international beneficiaries. The specification will be updated to cater for this in the next release, as a non-breaking change. Fixed
Open	TBC	Minor specification issue	Security profile: Spec not clear that query parameters in the authorize url should be url-encoded	The examples that are referred too were created as part of the “security profile implementation guide”. They don’t appear in the security profile in bit bucket. They should be updated / corrected to reflect url encoding as per oidc cores examples.	Some ASPSPs may mis-interpret the specification. The examples will be updated in due course to make things clearer. Security Profile Implementation Guide to be updated and published
Closed	CDRW-1206	Minor clarification	Inconsistency between Payments and Account specification should a ASPSP reject the request with a 403 if x-fapi-financial-id is invalid.	Accounts v1,1 seems to have dropped the following line from the spec inadvertently. "If the value does not match the expected value (based on the Client ID or network certificate of the caller, the ASPSP must reject the request with a 403 (Not Authorized) status code." This is in response to https://openbanking.atlassian.net/browse/OBSD-2643	Some ASPSP have already misinterpreted the specification and don't validate this header. Fixed

Read/Write Data API Specification - v2.0.0

This version of the Read/Write API Specification will be supported by all CMA9 ASPSPs from 7 September 2018 for CMA Order in-scope accounts. The following table details known issues with this version of the specification.

Status	Ref	Type	Issue	Details	Impact/Mitigation
Closed	OBSD-4103	Errata	OB Statements - Endpoint section specifies Filtering for wrong endpoints	Filtering word should be removed from the Endpoints table for: GET /accounts/{AccountId}/statements/{StatementId} (Row#2) GET /accounts/{AccountId}/statements/{StatementId}/transactions (Row#4)	Non-breaking change. The Swagger is correct for this issue, but the documentation has specified filtering on endpoints that should not apply filtering. Will be fixed in v2.1 Has been fixed in v3.0
Closed	TBC	Bug	OB Statements - filters missing in Swagger spec.	Filtering on statement dates is in the specification for: GET /accounts/{AccountId}/statements GET /statements However - these are missing from the Swagger spec.	Non-breaking change. TPPs may expect the ability to filter on dates to identify statements. However, this functionality is missing from the Swagger spec. Will be fixed in v2.1 Has been fixed in v3.0
Closed	TBC	Errata	Usage Guidance Errata	For Party Endpoint: Usage Examples for Account Owner and Authorised User - have been documented incorrectly.	Errata. Non-breaking change. Will be fixed in v2.1. Has been fixed in v3.0
Closed	TBC	Bug	Transactions Object Bug	Transactions object using the wrong currency exchange object. In v3, we have fixed this with the CurrencyExchange object replacing the EquivalentAmount object to describe currency exchange.	Breaking change to replace the CurrencyExchange object. ASPSPs cannot represent currency exchange information until this fix is applied. Will be fixed in v2.1 Has been fixed in v3.0
Closed	TBC	Errata	Address Code-LIst Errata	Updated ISO 20022 OBAddressTypeCode code from "DeliverTo" to "DeliveryTo"	Errata. Non-breaking change. Will be fixed in v2.1 Has been fixed in v3.0

Has been fixed in v3.0
Closed	OBSD-3833	Bug	/party endpoint AddressLine - mismatch between spec and Swagger	AddressLine in Swagger is specified as a string. However - in the data dictionary is 0..5	Non-breaking change. Will be fixed in v2.1 Has been fixed in v3.0

Open Data API v2.1

Open Data API Specifications v2.1.1

This version of the Open Data Specification will be supported by all CMA9 ASPSPs from 13 Jan 2018 and replaces v1.x. The following table details known issues with this version of the specification.

Status	Ref	Type	Issue	Details	Impact/Mitigation
Open	OD-803	Enhancement	Products: Need to split ServicingAccessChannel by individual services.	A request was made that AccessChannel be split in to:- I) SalesAccessChannel - channel(s) by which a product may be sold to a customer ii) ServicingAccessChannel - channel(s) by which an existing customer may obtain 1 or more services for a particular product.	Minor impact. Will be updated in v2.2.
Closed	OD-826	Minor bug	Regular Expressions (Regex), that are required to constrain values entered in to fields to a certain pattern, should be in the data dictionary as well as the Swagger.	Regex in Swagger is hard coded and there are a number of discrepancies (amount and rate fields) where these are limited to 2DP. They should be 3DP.	ASPSPs will only be able to specify amount and rates to 2 decimal places. Has been fixed in v2.2.0-rc1.
Closed	OD-845	Minor bug	OverdraftFeeApplicableRange section is a modelling error and should be removed from the PCA design.	OverdraftFeeApplicableRange doesn't appear in the Design at all but does appear in the swagger.	This is an optional field, so no impact. Has been fixed in v2.2.0-rc1.
Open	OD-855	Enhancement	PCA, BCA: Minimum Arranged Overdraft Amount.	Some banking products require an account holder to take an Arranged Overdraft of at least £x, or else a bank will not process an Arranged Overdraft request. This is potentially useful information. If, for example, an accountholder has an Arranged Overdraft of £100 currently, and a banking product that they're interested in taking requires a minimum Arranged Overdraft of £200, then they would not be able to switch their current account.	Minor impact. Will be updated in v2.2.
Closed	OD-856	Minor bug	All Notes fields should have a consistent cardinality 0..*	In some places cardinality is 0..1 and these should all be 0..n to allow multiple notes.	ASPSPs will have to combine notes into one field rather than separate fields. Has been fixed in v2.2.0-rc1
Closed	OD-857	Minor bug	The Max256Type datatype was not correctly generated in the Swagger files.	Swagger is a string but GFEG defines 256 characters. Swagger should be changes to 256.	No impact. Has been fixed in v2.2.0-rc1
Closed	OD-883	Minor bug	3 missing fee category codes.	FeeCategoryType1Code list is missing the following fields 'Auto', 'FX' , 'Investigation'	ASPSP can select other and chose one of these for now. No impact. Has been fixed in v2.2.0-rc1
Closed	OD-884	Bug	Fix the way that mandatory field restrictions are generated by the Swagger generation script.	Swagger contains required tag in the wrong place, which makes the Java Json Validator https://www.jsonschemavalidator.net/ fail.	ASPSPs cannot validate using Java Json Validator, but will have to use OB Json Validation tool instead. Has been fixed in v2.2.0-rc1
Open	OD-973	Minor bug	PCA, BCA, SMELoan and CCC amend spelling mistake in the codelist	There are a number of spelling mistakes in code lists (e.g. CoreProduct/ LoanApplicationFeeChargeType enumeration "NoLoanApplicationFee" is incorrectly spelt "NoLoanApplicatioFee" in swagger).	TPPs may see some values with spelling mistakes. Will be fixed in v2.2.
Open	OD-978	Enhancement	Enhance the Fee and charges Cap so that it can be linked with the any Fee Type.	Where there are tiered fees and charges, the current design only allows the ASPSP to use one cap across the tiers. ../OtherFeesAndCharges/FeeChargeCap unable to explicitly link to a ../OtherFeesAndCharges/FeeCharge Detail	ASPSPs can use notes field to specify complex caps. This item requires a decision as to whether it may be included in a future release.
Open	OD-979	Minor bug	Make the identification field optional for all section except Product ID	Some ID fields in PCA (e.g. <Product>MarketingState/Identification) are mandatory and should be optional to be consistent with BCA, SMELoans, CCC.	ASPSPs will have to populate with some value (e.g. 0). Will be fixed in v2.2.
Open	OD-980	Minor bug	Restriction on regular expression for Residency Included field should be removed.	For specifying the countries for which the PCA products are available/restricted to use the field ResidencyIncluded, current specification specifies it's DataType as OB_CodeMnemonic with a fixed length of 4. However, to correctly specify data values in this field, the correct DataType restriction should allow length of up to 4 and NOT fixed at 4. e.g. The value on this is expected to be 'UK' or 'EU', which would error out with the specification supplied.	ASPSPs will have to pad out the field (e.g. with spaces). Will be fixed in v2.2.
Open	OD-981	Minor bug	Check the possibility of changing the optional or mandatory fields as an array rather than objects.	For any fields where cardinality is 0..1, the swagger defines this as an object. For 1..1 and 1..n the swagged defines this as an array. Ideally these should all be arrays.	No impact. Will be fixed in v2.2.
Open	OD-986	Minor bug	Missing 'Other' code from Fee Type under overdraft fee charge details and cap section.	In PCA and BCA schema the FeeType Enum in the OverDraftFeesCharges of overdraftTierSet and OverDraftTierBand are missing the "Other" value in both OverdraftFeeChargeCap and OverdraftFeeChargeDetail.	ASPSPs can only specify fee types using the standard code list. Minor impact, as code lists are fairly comprehensive. Will be fixed in v2.2.
Open	OD-997	Enhancement	Add "Academic Term" in period code list.	The current code list options for: OpenBankingPCA/Brand/PCA/PCAMarketingState/StateTenurePeriod should be extended to include: AcademicTerm.	Some ASPSPs may have to use Monthly, Quarterly, Yearly for now. Minor impact. Will be updated in v2.2.
Open	OD-1010	Minor bug	Remove the example reference url link from the base of the API URI	Current URLs for V1.2 and the Swagger which implies a different configuration. Current example: https://openapi.nationwide.co.uk/open-banking/v1.2/atms Our assumption is we would just change the version number however Swagger suggests a new part of the URL is being added: “/reference-implementation/open-banking/v2.1”	ASPSPs should remove/replace 'reference-implementation' with their own URI. Minor impact. Will be fixed in 2.2.
