Version | Date | Description of Changes |
Bahrain OBF v1.0.0 | 25th Aug 2020 | Initial Release |
2. Overview
The Operational Guidelines set out criteria, guidance and requirements for Account Servicing Payment Service Providers (“ASPSPs”) to deliver an effective Open Banking ecosystem and meet the needs of Account Information Service Providers (“AISPs”) and Payment Initiation Service Providers (“PISPs”) in providing services to users/customers.
...
Improve efficiencies: Minimize the potential impact to a business when systems or supporting networks are down (including instances where they have not been tested appropriately)
Reduced Reduce Reputational Risk: Protect the reputation of ASPSPs/AISPs/PISPs and the Open Banking ecosystem as a whole
3. Availability and Performance
This section outlines various API availability and performance requirements and recommendations for ASPSPs in Bahrain. AISPs and PISPs are dependent on the well-established interfaces provided by ASPSPs so that they can in turn provide reliable services to their users/customers.
3.1 Key Indicators for Availability and Performance
The following tables set out, for each requirement:
...
Additionally, the guiding principle of these benchmarks is that ASPSPs must ensure (at least) parity between the availability and performance of the best performing interface (that they own and maintain to interact directly with customers) and that of their Open Banking interface which may be leveraged by AISP/PISPs.
3.1.1 Availability
The definition of a period of availability is a period of time when any of the API end points defined in the Bahrain Open Banking Framework (Bahrain OBF) are able to reliably provide a successful response to an appropriately constructed request.
...
Title | Requirement | Calculation Guidelines | Recommended Benchmark |
The uptime per day of all interfaces | For the purpose of calculating the availability indicators, the ASPSP should:
| For each 24 hour period, uptime is calculated as 100% minus the total percentage downtime in that period. | A quarterly uptime of 99.5%[1] |
The downtime per day of all interfaces | For the purpose of calculating the availability indicators, the ASPSP should: a) calculate Calculate the percentage downtime using the total number of seconds the API was down in a 24 hour period, starting and ending at midnight
b) count Count the interface as ‘down’ when five consecutive requests for access to information for the provision of payment initiation services, account information services are not replied to within a total timeframe of 30 seconds, irrespective of whether these requests originate from one or multiple PISPs/AISPs. In such a case, the ASPSP should calculate downtime from the moment it has received the first request in the series of five consecutive requests that were not replied to within 30 seconds, provided that there is no successful request in between those five requests to which a reply has been provided | Downtime should be calculated as follows:
At a minimum, downtime should be measured if:
This should include any vendor/supplier failures in the case where the ASPSP has contracted the vendor/supplier to deliver a related service. However, this should exclude errors resulting from issues not directly attributable to the ASPSP, such as issues with AISP/PISP software, infrastructure or connectivity. | A quarterly downtime of 0.5%. (approx. 11 hours per quarter, or just under four hours per month, to allow for planned releases, updates, and also any unplanned downtime). |
[1] This is the benchmark for business as usual/normal conditions and not in cases of force majeure events such as natural calamities, war, cyber threats etc.
3.1.2 Performance
The Bahrain OBF defines a number of endpoints which should be made available by ASPSPs. The Performance of API end points should be measured in response time of individual API requests from receipt of request to delivery of response. While all supported endpoints should be included by ASPSPs when calculating error rates, for reporting response times the consent endpoints should be ignored, as these are not considered part of the process of 'providing the information requested' to the AISP/ PISP for account information or payment initiation.
...
Title | Requirement | Calculation Guidelines | Recommended Benchmark |
PISP response time | For the purpose of calculating the performance indicators, the ASPSP should: a) calculate Calculate the daily average time (in milliseconds) taken, per request, for the ASPSP to PISP with all the information requested | The "time taken per request" should be calculated for each day using the mean value of Time to Last Byte (TTLB) measured in milliseconds, starting from the time that each endpoint request has been fully received by the ASPSP and stopping when the last byte of the response message has been transmitted to the PISP. The following API endpoints should be included when calculating PISP response times, for each endpoint supported by the ASPSP:
The ASPSPs signed response to the POST will inherently act as proof of receipt of the payment order by the ASPSP, which will enable the PISP to log a reference and the date of this receipt. Both the POST and the GET endpoints contain all information relating to the payment, which, depending on the payment type, should include reference, amount, exchange rate, charges, and status (which may change between POST and any subsequent GET). The POST endpoints above cater for the ASPSP to make the information available to the PISP immediately after receipt of the payment order, and the provision of all information on the initiation of the payment transaction and all information accessible to the ASPSP regarding the execution of the payment transaction. The GET endpoints cater for the ASPSP to provide confirmation to the PISP that payment initiation has been successful, in order to enable the PISP to provide this information to the user/customer. Since different endpoints will have different payload sizes for request and response (especially relevant for bulk/batch payment endpoints involving large files), and in order to facilitate a 'like for like' comparison with user/customer interfaces, ASPSPs should report on the average time per megabyte (MB). This can be calculated by dividing the total response time in milliseconds by the total payload response size in MB, across all API calls for all API endpoints for each day. | An average TTLB of 750 milliseconds per response for all but bulk/batch payments. |
AISP response time | For the purpose of calculating the performance indicators, the ASPSP should: a) calculate Calculate the daily average time (in milliseconds) taken, per request, for the ASPSP to provide the AISP with all the information requested | The "time taken per request" should be calculated for each day using the mean value of Time to Last Byte (TTLB) measured in milliseconds, starting from the time that each endpoint request has been fully received by the ASPSP and stopping when the last byte of the response message has been transmitted to the AISP. The following API endpoints should be included when calculating AISP response time, for each endpoint supported by the ASPSP:
Since different endpoints will have different payload sizes for request and response, and in order to facilitate a 'like for like' comparison with user/customer interfaces, it is recommended that ASPSPs also report on the average time per megabyte (MB). This can be calculated by dividing the total response time in milliseconds by the total payload response size in MB, across all API calls for all API endpoints for each day. | An Average TTLB of 750 milliseconds per response, or per page of results for up to 100 records for larger payloads. In practice, all but transactions and statements are likely to be small payloads without pagination. |
Confirmation of Funds (CoF) response time (PISP) | For the purpose of calculating the performance indicators, the ASPSP should:
a) calculate Calculate the daily average time (in milliseconds) taken, per request, for the ASPSP to provide the PISP with a ‘yes/no’ confirmation
| The "time taken per request" should be calculated for each day using the mean value of Time to Last Byte (TTLB) measured in milliseconds, starting from the time that each endpoint request has been fully received by the ASPSP and stopping when the last byte of the response message (i.e. the 'yes/no' confirmation) has been transmitted to the PISP. The following API endpoints should be included when calculating CoF response times for PISP:
| An average TTLB of 300 and a max of 500 ms per response. |
Daily error response rate | For the purpose of calculating the performance indicators, the ASPSP should: a) Calculate the daily error response rate – calculated as the number of error messages concerning errors attributable to the ASPSP sent by the ASPSP to the PISPs, or AISPs per day, divided by the number of requests received by the ASPSP from PISPs or AISPs in the same day
| It is not possible for ASPSPs to respond to AISPs/PISPs with an error message where no TLS (Transport layer security) session has been established. However, ASPSPs should still be able to respond, measure and report on errors relating to endpoint calls and all functional API calls. The error response rate should be calculated as the total number of all 5xx HTTP status codes from all API endpoints per day, divided by the total number of AISP/PISP API requests received across all of these endpoints in the same day, and expressed as a percentage. Errors based on 4xx HTTP status codes are largely attributable to AISP/PISP or user/customer actions or failures, and hence should not be included here. | An average of 0.5% across all endpoints. |
3.2 Traffic Thresholds
The CBB may leverage the monitoring reports submitted by the ASPSPs and other parties, to decide on the traffic thresholds. Basis the usage and adoption of these APIs, the related structures for threshold limits may be established on a future date.
Until the CBB decides on these thresholds, ASPSPs must provide data access to AISPs/PISPs through API calls without any limits or charges.
3.3 Publication of Statistics
ASPSPs must publish to the CBB, statistics on the availability and performance of APIs on a monthly basis as set out in these guidelines.
These statistics should be completed for every API. In case where an ASPSP maintains different versions of their APIs in parallel, then these should be considered as separate APIs and published separately, as they may have different levels of availability and performance.

3.4 | User/Customer used AIS for the first time | The number of unique users/customers who have authorised access to their account(s) to one or more AISPs for account information services for the first time during the reporting period. For the avoidance of doubt, this refers to new consent/authorisations and not re-authorisations. |
3.5 | User/Customer re-authorised for using AIS | The total number of unique users/customers who have previously authorised access to their account(s) to one or more AISPs for account information services and had to re-authenticate to refresh the account access at least for one of the AISPs during the reporting period. |

For the avoidance of doubt, a user/customer initiating a payment (e.g. single domestic) using a PISP A and then initiating another payment of different type (e.g. international) using a PISP B within the same ASPSP , should not be double-counted. For business customers, unique users/customers should refer to all employees of the business who have separate authentication credentials and can be identified separately. Multi-banked users/customers cannot be identified so they may be double-counted by different ASPSPs. |

3.3.1.1 Reporting Template
A reporting template has been provided by the CBB that ASPSPs might find useful in preparing their information for publication and reporting to the CBB. Please refer – Operational Guidelines Reporting Template v1.0.0 for the template.
...
ASPSPs must publish their statistics using this template to the CBB on a monthly basis. Additionally, the CBB may request ASPSPs to publish their statistics using the template along with the calculation methodology as and when needed. This will enable the CBB to track the overall health and growth of the Open Banking ecosystem.
...
In the absence of any relevant information, the ASPSPs must return with a “NIL” response.
3.3.2 AISP/PISP Reporting
AISPs and PISPs should report statistics on availability and performance to the CBB (leveraging the same template as ASPSPs) on a quarterly basis.
4. Dedicated Interface Requirements
This section provides guidance for ASPSPs to demonstrate that their dedicated interface has been designed and tested in line with the requirements laid out in the Security Standards and Guidelines and the CBB Rulebook.
...
The Bahrain OBF has outlined customer experience requirements and considerations for ASPSPs to consider to support supporting the adoption of Open Banking in Bahrain.
4.1 Testing
4.1.1 Testing Facility
ASPSPs are required to provide a Testing Facility or sandbox to allow AISPs/PISPs to undertake connection and functional testing of their products and services using non-user/customer (i.e. “dummy”) data. The issues and problems which are identified within this testing process, as well as feedback and engagement from the AISP/PISP community, are useful for ASPSPs in alerting them to potential issues within testing that may also be encountered within the production environment. This can be used to identify and address issues early on.
...
Functionality: The facility should include all functionality of the production interface relating to AISP and PISP use cases. This functionality should work in an equivalent or representative way to the production interface including negative use cases and error codes
Security: The facility should use the same security profile/model and be configured in the same way as that which protects the production APIs
On-boarding: The facility should replicate the on-boarding process of the ASPSP's production facility, including AISP/PISP on boardingonboarding
Test data: The facility must not include any real user/customer data. The volume and variance of data should be sufficient to support all technical and functional testing including pagination (where this is supported in the dedicated interface)
Test accounts: The facility should provide AISPs/PISPs with a number of test accounts that enable the functionality and access to data that real users/customers will experience in production
Authentication: The facility should enable AISPs/PISPs to use 'headless authentication', i.e. authentication which does not require a user/customer to be present, therefore enabling multiple tests to be run in succession via automated scripts. Additionally, ASPSPs to allow AISPs/PISPs to test all authentication procedures provided to its users/customers, but ideally ASPSPs should not prevent 'headless authentication' testing to be conducted by the AISP/PISP as well. This may be catered for by ASPSPs either:
...
[2] For the avoidance of doubt, the following are all recommendations only and optional for ASPSPs, unless referring to direct regulatory guidance.
4.1.2 Publishing Specification Details
ASPSPs should publish the details of the specifications on their website well in advance before the ASPSP’s dedicated interface is launched.
...
Connection details (including all technical and business processes required to connect)
Methods of authentication available to users/customers (e.g. OTP via SMS, Fingerprint etc. and how this varies by device)
Authentication flows supported (e.g. redirect, decoupled)
Functionality and data elements for each AISP and PISP endpoint, including which optional elements are/are not provided
5. Change and Communication Management
This section outlines various change scenarios that may impact AISPs/PISPs and provides guidance for an ASPSP to consider when implementing a change and communicating to AISPs/PISPs.
...
The information that an ASPSP should include in its communication to an AISP/PISP is listed at 4.4 Notification of a change.
5.1 Downtime
Downtime is defined in Section 2.
...
ASPSPs should make this plan available to AISPs/PISPs (e.g. on their website or developer portal) so that they know in advance what to do in the event of unplanned downtime.
5.2 Implementing changes to the Bahrain Open Banking Framework
The Bahrain Open Banking Framework (Bahrain OBF) will continue to evolve over time to cater for potential improvements/clarifications, agreed Open Banking roadmap requirements and approved changes (which may include adding new functionality, fixing defects, and errata). Where possible, new versions of the Bahrain OBF will be scheduled with sufficient time for change so that ASPSPs can plan ahead and build new APIs to this plan, this will therefore reduce development and support costs for all participants and increase adoption.
5.2.1 Introducing Change
This section details out the guidelines for ASPSPs to communicate the change in their interface to an AISP/PISP and the following conditions are recommended:
ASPSPs must be compliant with the latest version of Bahrain OBF in order to meet both regulatory and commercial requirements
ASPSPs must publish technical specification documentation for their dedicated interface, well in advance before the target date of the market launch of the dedicated interface
ASPSPs must give AISPs/PISPs at least three months’ notice of any change to the technical specifications, unless the changes can be rolled out sooner, in which case ASPSPs must notify AISPs/PISPs on the change as soon as possible . In practice, this means that ASPSPs must give such notice if they are planning to introduce any updates to any component of the dedicated interfaces, Any change may be implemented in an emergency situation (e.g. in the case where there is a security issue) without such notice, and in such situations ASPSPs must document emergency situations where changes are implemented and make the documentation available to competent authorities on request
ASPSPs must also make available a testing facility (sandbox) well in advance before the target date of the market launch of the dedicated interface. ASPSPs should ensure that any changes are made available in the testing facility as soon as possible to allow AISPs/PISPs to test against the updated technical specifications. In practice, this means that ASPSPs should consider the impact of proposed changes on their testing facility in order to ensure that the testing facility enables the same functionality as the dedicated interface, in the context of such changes. As such, ASPSPs should endeavor to make any changes to the testing facility available to AISPs/PISPs at least three months before changes are implemented to ensure AISPs/PISPs, can continue to effectively test
ASPSPs should maintain multiple live/active versions of each interface (e.g. one for each supported release)
Where an ASPSP decides to implement a new version of any component of the Bahrain OBF they should implement each new major version within six months, and each new minor version within three months of the Bahrain OBF being published
Together with the requirements for ASPSPs to notify AISPs/PISPs of any changes any AISP/PISP will, except in an emergency, always have at least three months’ notice before being required to update their systems
5.2.2 Considerations
5.2.2.1 Dual Running and Depreciation
This section details out the requirements to be followed by the ASPSPs during the instance of new API version migration. ASPSPs should support a minimum of two API versions in a production context if both versions were previously supported by the ASPSP. Dual running for at least six months for a major version, and three months for a minor version. This is to ensure that AISPs/PISPs have had sufficient time to successfully test the new version of ASPSPs and migrate their applications and customers. An ASPSP implementing an API for the first time will only need to support one version to start with.
...
The deprecation of unsupported versions is at the ASPSP's discretion - based on usage metrics. However, the CBB may recommend that any specified version should be deprecated at any time, and this should be implemented within a fixed period of time as notified.
5.2.2.2 API Credentials, Consent and Authorization
API Credentials associated to an API should be version agnostic. Therefore, an AISP/PISP accessing v1.0, v1.1 or v2.0 should be able to use the same API Credentials across all available API endpoints.
...
In the event of a breaking change (e.g. where a permission/cluster is added, removed or changed) or a non-breaking change (e.g. an additional field is added to a permission/cluster), then the user/customer may be required to re-consent with the AISP/PISP and to re-authenticate with the ASPSP.
5.2.2.3 Backward and Forward Compatibility
The API specifications will include details on which operations or resources are expected to be backward and forward compatible across versions. It is expected that:
...
