GSMA Mobile Money API

As the reach and impact of mobile money increases, so do the demands on the technical platforms that underpin mobile money. Substantial work is required to connect multiple partners in the ecosystem. If mobile money platform vendors each implement their own bespoke API solutions, ecosystem solution vendors are required to implement separate integrations for each mobile money platform. Ultimately bespoke APIs will limit the growth of the mobile money ecosystem by causing fragmentation of vendor service APIs, per platform, per service and per region.

What is the GSMA Mobile Money API?

The GSMA Mobile Money API is an initiative developed through collaboration between the mobile money industry and the GSMA, aimed at helping the mobile money industry speak the same technical language by providing a modern harmonised API for mobile money transactions and management that is both easy to use and secure. This common technical language, the API Specification, enables easy integration between mobile money providers and organisations who want to interface with these providers, by allowing any third party to implement a common solution which will work with all mobile money platforms which implement the API. The API is based on RESTful principles, a common easy to use set of principles used in modern APIs which provide benefits such as flexibility and scalability. The Specification also provides best practice security recommendations to ensure a high level of security.

The GSMA harmonised API initiative aims to increase adoption of the mobile money API through dedicated engagement with mobile money providers and support for ecosystem vendors. The GSMA also aims to maintain updated versions of the API Specification with new features and up to date functionality.

Use Cases

The Mobile Money API supports the core set of mobile money use cases:

  • Interoperability between mobile money and banks, and between mobile money providers;
  • Merchant payments, online and offline (including delegated authentication);
  • Bill payments (including instant payment notification);
  • Basic account management;
  • International transfers (including quotations);
  • Bulk transactions; and
  • Cash in/out.

Design Principles

The Mobile Money API uses best practices from the technology industry in API design and security.

  • Use of REST architectural principles;
  • Providing a set of well-defined mobile money objects;
  • A standard set of transaction types;
  • Use of ISO international standards for enumerations such as currency and country codes;
  • Support for supplementary metadata for bespoke properties; and
  • Best practice security guidelines.
