Open APIs & Protocols

Solace facilitates integration with applications, other middleware, and data movement technology with support for open APIs like JMS and OpenMAMA, and open wireline protocols such as AMQP, MQTT and REST. This allows you to get real-time data flowing between diverse applications, big data systems, cloud services and IoT devices.

AMQP 1.0

Solace PubSub+ software event brokers support AMQP 1.0 as a component in Solaceʼs multi-protocol, any-to-any messaging solution based on open source and open standards.


Solace supports the OASIS MQTT 3.1.1 and MQTT 5.0 standards to meet the needs of connected devices and mobile applications that need an efficient way to send and receive information that requires very little client-side processing power, memory and/or bandwidth. The Solace PubSub+ event broker works with any third-party MQTT 3.1.1 or MQTT 5.0 compliant client API, including open source APIs available via an Eclipse initiative called Paho.


The Open Middleware Agnostic Messaging API (OpenMAMA) is an open source, lightweight, vendor-neutral integration layer for sending and receiving market data information supported by the Linux Foundation. With unified support for many different kinds of data distribution in a compact, cost-effective platform, Solace PubSub+ is the ideal foundation for OpenMAMA-based market data distribution systems.


The Solace REST Messaging API allows HTTP clients to send and receive messages with an event broker using HTTP POST requests. This enables REST clients to send messages to and receive messages from any Solace PubSub+ event broker clients without needing to use any Solace-provided API.
