GSMA Mobile Money API Specification vs Mojaloop Open API for FSP Interoperability Specification

The GSMA Mobile Money API is a harmonised, industry-governed REST and JSON specification covering common mobile money use cases such as merchant payments, disbursements, P2P and international transfers, bill payments and account linking. It defines a standard set of transaction types abstracted from provider-specific implementations and ships a developer portal with a sandbox simulator, an OAuth 2.0 gateway and SDKs. Version 1.2 is the current release.

The Mojaloop specification set defines an open API for interoperable transactions between financial service providers, enabling a payer at one provider to pay a payee at another. It documents the FSP Interoperability (FSPIOP), Administration, Settlement and Third-party Payment Initiation APIs and is published under a Creative Commons license. It is the reference standard behind several national instant payment switches used in Africa and beyond.
