Python API

The Solace PubSub+ Messaging API for Python (version 1.7) can be used in cloud-based and enterprise-scale server applications. To use this API, we recommend that you have Python 3.7 or later installed. The Python, Go, Node.js, and JavaScript Messaging APIs share the same asynchronous and non-blocking programming model, but are packaged differently, and optimized for their respective target environments.

Message Exchange Patterns

The PubSub+ Messaging API for Python supports the following message exchange patterns:

  • Publish / Subscribe
  • Request / Reply

For more information, see Message Exchange Patterns.


For the list of features that are supported for the PubSub+ Messaging API for Python, see the Python column in the table in Feature Support in PubSub+ Messaging APIs.

Get Started

These tutorials help you to quickly get up to speed developing applications using the Solace PubSub+ Messaging API for Python. As part of using Python, you might want to use an integrated development environment. To ensure the code hints work properly, you may need to configure your IDE settings. For more information, see Python API.

Before you can start working with the API, you must have access to a PubSub+ event broker. For more information about PubSub+ event brokers, see Getting Started with PubSub+ Event Brokers.

Getting Started with PubSub+ Event Brokers

To test and use your the Python application, you require a PubSub+ event broker.

There are three ways you can get started using a PubSub+ event broker:

  1. If you have PubSub+ event brokers already deployed, obtain the hostname or IP address of an event broker to test against, a username and password to access it, and a Message VPN in which you can produce and consume messages.
  2. You can set up a software event broker as a container or machine image. For more information, see one of the following:
  3. You can spin up an event broker service, which is a SaaS-based software event broker running in PubSub+ Cloud.
