Upgrade to OAS version 3
• Mobile Money API version 1.1 has been developed using OAS version 3 to take advantage of the new modelling and schema reuse capabilities that OAS3 provides. This has led to significant reuse of schemas/properties and has significantly improved readability.
Overhaul of Callback mechanism
• In version 1.0 of the mobile money API, callbacks were issued via a patch command with clients unable to specify a URL to receive the callback. In version 1.1, the following improvements have been made:
o The client can specify full callback URL using a new request header X-Callback-URL.
o A full representation of the created resource is sent back (via PUT) in response to a successful creation request.
o Mobile Money API callbacks have been modelled using callback operations introduced in OAS v3.
Improved implementation of identifier types in path
• The Mobile Money API now permits any Identifier Type in path, not just MSISDN:
o Original version 1.0 implementation: /accounts/msisdn/{msisdn}/
o New version 1.1 implementation: /accounts/{identifierType/{identifier}/
New APIs for Bill Companies
• New set of APIs to enable clients to retrieve Bill Company information.
New Authorisation Codes APIs
• Provide the ability to generate & cancel transaction authorisation codes which can expire.
• Provides support for ATM withdrawals & voucher code-based transactions.
New API - POST /transactions/type/{transactionType]
• Enables the transaction type to be identified in the URL when creating a transaction.
• This is required in some API Gateway implementations to allow fine grained API permissions to be applied.
Account Balance ‘Self’ API
• Added new ‘self’ API for account balance, removing the need for the account subject to identify itself in the path.
