However, TESOBE will use its reasonable endeavours to provide the best possible quality of service and to maintain the Sandbox so as not to cause disruption to its users.

To start using the Services, Users need to create an account on the Sandbox.


Developers are provided with Consumer Keys which are enabled by default. The Provider or its partners may review and disable Consumers.


The Sandbox supports four authentication methods:

  • OAuth 1.0a (industry standard, secure, used by Mastercard and Twitter)

  • OAuth 2 + OpenID Connect from providers such as Google.

  • Direct Login (easier to use than OAuth, useful for hackathon contexts and trusted applications, uses JWT)

  • Gateway login only if specifically enabled for a trusted internal environment.


We recommend the use of Direct Login for the purpose of using this sandbox for ease of use.

12 API Versioning


API Versions. It is understood that TESOBE will periodically deploy new versions of the API sandbox to incorporate new features and fixes. TESOBE will periodically retire API versions as per the policy below.


API Version Naming, compatibility and life time (For versions greater than 2.2.0,) the API versioning used by OBP is based on SemVer (http://semver.org/) i.e. X.Y.Z where X is the major version, Y is the minor version and Z is the patch.


The version can be specified via the URL e.g. /obp/v1.2.1/banks

Note that you cannot specify build versions (e.g. v1.2.1+r3456) via the URL.


If you want to be sure to get a certain version, specify the full patch e.g. 1.3.4. If you do not specify a patch version e.g 1.3 instead of 1.3.4 we may return the highest patch version available for that minor version i.e. 1.3.9


TESOBE ensures that the last three minor versions are available on the OBP API server. e.g. if versions 2.3.0, 2.4.0 and 3.0.0 are available on the server and 3.1.0 is added, 2.3.0 may be removed as long as the minimum lifetime of a minor version is respected.


The minimum lifetime of a minor version is 6 months.


Developers should check the root endpoint for API status regarding end of life.


Versions marked as –alpha or –draft are subject to change without notice.


Build versions may change without notice.
